Lasik Eye Guide

Millions of the people around the globe have issues related to visual impairment that include near sightedness, long sightedness, astigmatism, myopia, etc. They ultimately have to depend on either of the assistances such as glasses or contact lenses to rectify the issue irrespective of their intensity therefore giving them a vision that they could certainly rely on. There had been many kinds of surgeries available in the world of opticians and optical surgeons to solve the issue but none was reliable and accurate as the Wavefront Surgery range.

The conventional and traditional surgeries were not able to give results accurate and reliable as does the wavefront surgery range. The wavefront eye surgery is something that people have started opting in bulks despite its cost being really high. Their dependency on optical instruments such as glasses and lenses has reduced considerably. The surgeons now perform the wavefront surgery in whatever way that suits you the best depending on the type of issue and structure of your eye through the customizing option available for wavefront surgery.

The wavefront surgery is said to have adapted from technologies that are used in astronomy. It involves a combination of micro sensors and lasers. A wave of light is entered through your eye through the retina using the laser. The micros sensors are developed in a way as to look out for all the abnormalities that exist in the structure of your eye. All the irregularities that are sensed by the micro sensors are then drawn automatically, giving the surgeon a clear picture of the complete eye structure of the subject along with the locations and types of all the abnormalities that exist in the eye. Two people might have the same glasses for their visual issues but no two people can have the same wavefront measurements as they are distinct for everyone. This probably is the reason for the accuracy that it renders.

The issues are then calculated and the surgeon makes a clear perspective about all the required alterations. An ultraviolet cold laser beam is used in order to vaporize tissue within the eye and remove all the excess tissues from the cornea making it perfect for producing an optically vibrant image. This high tech process tends to produce fewer aberrations that usually result into the formation of glares, haloes and blurry images. In this manner, the wavefront surgery gets you a vision that does not have any other issues unlike many other surgeries present on the planet.

Night vision has been a major subject of discussion in all the times and no other surgery type was able to solve it properly as none of those treatments solved the issue to such an extent. The wavefront surgery has resulted into improved results in low or dim light therefore reducing the number of complains about low night vision. Out of a study, it has been known that 70% of the people who had issues with glasses and lenses during night time were extremely satisfied with the vision’s performance after going through the Wavefront Surgery.

A completely new version of surgeries in form of the wavefront laser has completely taken over the market because of their precision and accuracy. The Wavefront Laser Eye treatment is perhaps the best treatment that you can go for in order to get the “Super vision” that makes you able to see it all. The conventional treatments haven’t done such a great deal as this type of treatment as you can easily get rid of all your vision impairment issues through this. The wavefront laser eye treatment is expensive but it is worth the price that you might pay for it. The reason to this is that you can get multiple issues sorted out with the same surgery and ultimately you get a vision that is perfect in every aspect. People who have developed issues by the traditional eye surgeries can easily get rid of these issues through the wavefront laser eye surgery. People around the world have got benefits out of this type of surgery and have reviewed this treatment to be the best one to get you vision close to perfect.

As described above, the wavefront laser eye surgery is expensive but the price is justified as it involves some of the very high tech machinery as well as the expertise of the surgeon to perform it in a way as to give the most accurate results. This surgery would cost you on an average $1800-2500 that would bring an end to many problems that might be persisting with your vision. Wavefront measurement system is used in all the process and that is why the surgery itself is named as wavefront laser eye surgery. A computer generated system generates 8000 waves of light that enter your eye. These waves enter eye at different angles therefore different observations are made in order to check for the response of your eye to the light waves. This ultimately helps the computer draw a blueprint of the mechanism your eye is following in order to produce an image. All the faults in the optical formation of image are observed therefore and an image is drawn to produce an accurate surgical treatment.

In addition to the obstructions only, a blue print of the whole eye is generated as to make sure that all the organs are in right order and place. Any minor abnormality is being catered in the surgery making it friendly with light and ensuring the production of accurate images. The blueprints of your eye are accurate enough because of the same wavefront measurement system being involved in the measurement. These drawings assist the computer guided laser to alter the eye structure to produce images vibrant and clear.

Compared to all the different equipments and procedures available in the market to enhance your vision, this is perhaps the most effective yet the most expensive one. It gives you a vision that is pretty close to the perfect one if by chance you can’t get a perfect one making it a consideration for many of them around the globe.

For those who have major defects with their vision that is impairing their lives, Wavefront Laser Eye Surgery is something of a great attraction. The process is one of the most expensive ones around on the planet but tends to provide you with the most precise results at the end giving you a vision that is perfect as the default one. A worldwide analysis shows that people have noticed remarkable results in their vision after they have undergone Wavefront Laser Eye Surgery. Many of them are of the point of view that they have been provided with accurate vision after the surgery and are very satisfied with the way it is going. Even people who have formed defects because of the surgeries that they have undergone earlier have found this to be the best way to get rid of all the abnormalities.

Despite being one of the very friendly surgeries, Wavefront Laser Eye surgery is perhaps the most expensive of the surgeries that are available on the planet with the price ranging somewhere between $ 1500-2500. The complete process involves some very high tech computerized equipment that guides the surgeon through the whole process therefore ensuring the accuracy of the process. The first of the steps is an assessment of subject’s eye through computer based Wavefront standards. This wavefront measurement system sends around 6-8 thousand waves in the eye at different angles and monitor closely the response all the eye structures give on exposure to such amount of waves of light. The responses are observed closely as to get the accurate picture of the internal structures of your eye.

The internal and external structure of your eye is also monitored using the wavefront measurement system. The size of your pupil, iris and cornea are all measured. Three dimensional diagrams are generated by the computer based technology that gives you the most accurate blueprints of your eye. The surgery completely depends on these images. These images also tend to give you the complete picture of all the hindrances that might obstruct the formation of accurate image on the cornea.

There are many optical methods that improve your vision considerably. These include glasses and lens but one thing that most of us over look is that the genuine eye gives you a stereotypical vision that means that you have just one image transformed out of both the eyes that is unique as an image while both the glasses and lens give you an image that does not completely give you stereotypical vision. Wavefront Laser Eye Surgery is something that would cost you more but will give you the complete vision that GOD has created by default. It would also help you get rid of the many issues that you might have with the optical enhancements. These problems normally include blurry vision and halo effects during night time. This has made driving an issue to many people and they are not able to drive through nights. The fact is that the halo effect is caused when your eye cannot balance the contrast ratio of light. This causes low vision in low or dim light. All these issue can be easily treated with the Wavefront Laser Eye Surgery.

Wavefront Laser surgery tends to provide you with results that you are not able to achieve through your standard treatments as well as glasses through all the time. A general statistical study shows that almost 97% of the people achieved standard driving vision after the surgery. There were around 85% people who have achieved the 20/20 vision after the treatment and around 35% of the people are extremely satisfied telling that the Wavefront Laser surgery has brought those even better results than their glasses before the surgery. Wavefront surgery is also applicable to you even if you have undergone any other type of surgery before this consideration making it a very friendly option.

Anyone who opts for the laser surgery is being is being closely observed using some of the very high tech machines present around the world. The first inspection is the shape of the eye, both internal and external through the wavefront measurement system that is found to be the most precise system around the globe and tends to give you the most accurate measurement. The assessment involves all the diagrams of the internal structure of the eye upon which the surgery would be based. In addition, this computer based measurement and assessment looks for all the defects that are causing the image formation to be abnormal and not clear. The beam of light and the image formation is all monitored to check the exact state of optical performance.

The glasses tend to improve the state of your vision by a considerable degree and the masses are using the glasses technology as this is helping many get rid of their issues. The wavefront laser surgery tends to improve the state of both your eyes giving you the perfect stereotypical vision as the standard human. In addition, night time vision is something of a great concern to everyone around the world. People who have developed a large pupil usually have issues with the night vision as their contrast sensitivity is not as good as a normal eye. The process involves the assessment of your eye under multiple conditions and multiple amount of light exposure as to get the real picture of your eye and the issues that persist. The Wavefront laser surgery, therefore, tends to rectify all the issues making your eye extremely sensitive to all the contrast ratios as well as light exposures.

 The wavefront laser treatment involves some of the very high tech machines to do all the work for the surgeons making it the most accurate surgery around the world. The first machine that is being used in the whole process is the optical path difference device that measures progress of some specific number of waves of light that are passed through multiple parts of your eyes at different angles. This gives you the response of your eye to light at different angles. The machine also recognizes the way your Iris is working and tracks the complete eye in less time. The complete examination is followed by the laser alterations that tend to correct all the issues making your eye perfect.

Custom Wavefront LASIK is one of those surgeries that has brought a reform in the world of medicine and surgery. The precision of wavefront and the effectiveness of laser has brought such a combination to the world of medicine that it is said to create miraculous effects. The surgery is said to have the potential to improve your eye sight and give you the super vision that you would ever want. The type of LASIK has brought results that give 20/20 on the eye chart that is available to opticians around the world. It also gives you a clear vision so that whatever you notice on the chart is clear enough and you can see that well enough giving you complete contrast details as well as color ratios. In addition, the number of risks involved in the traditional versions is minimized giving you no blurry and halo visions at any time of the day with any amount of light exposure.

The lower order errors in the eye as myopia, hyperopia and astigmatism disturb the amount of stuff you can see and can be treated with the traditional LASIK while the quality of vision is something that the traditional version cannot deal with easily. The best solution to the refractive errors therefore is Custom Wavefront LASIK surgery. These complicated issues that involve in the refractive errors disturb your vision when your sight confronts a difficult situation. This might involve a less contrast sensitivity, night vision, glare, shadows and halos. Custom Wavefront LASIK treats both the low level errors and the high level refractive errors as well.

With Custom Wavefront LASIK, you can easily achieve 20/20 vision as well as your eye would be completely sensitive and effective to all the contrast ratios available on the planet. It would give you the perfect vision even through the night time just like the default vision type therefore relieving you from many issues that might persist. The traditional LASIK might make you lose the perfect vision while Custom Wavefront LASIK is the solution to attain it back. This has made this LASIK type the best and the most expensive in the market.

Custom Wavefront LASIK, basically, gets the entire eye surface corrected therefore giving you the perfect and the precise vision that you would ever want. It tends to soothe the paths that light follow within your eye and the complete mechanism with which you eye produces the image is revitalized therefore giving you the type of result that you want. What you get at the end of the surgery is a vision that can be termed as “super vision” because it deals with all the scenarios the same way as the perfect eye does.

Poor contrast sensitivity is an issue to many a people around the world. They have been unable to see through night times or in dim of low light. Custom Wavefront LASIK is the best way to get this issue sorted out that makes you eye more sensitive to the contrast and color ratios making it possible for you to see through night.

Wavefront LASIK Eye Surgery or Wavefront guided LASIK are two names to the same type of surgery. This is sometimes even called customized LASIK surgery. This is not one of the many mandatory surgeries that might exist in the medicine world for people who have eye sight defects but is one of the surgeries the selection to which is on your very own disposal. The success and failure of the surgery completely depends on the precision of the equipment used and the expertise of the doctor performing the surgery.

Wavefront LASIK eye surgery is perhaps a combination of LASIK surgery, with the ophthalmologist applying a distinct yet different correction into the eye. A computer completely monitors the installation of the correction therefore making sure that it is guided at the right place and the results would be completely positive. The accuracy of such surgery is being ensured by the high technology that is being used in the process.

The Wavefront LASIK eye surgery is the type that is pretty different from the conventional types of LASIK surgery where they just focus on the rectification of the focusing power of the cornea. Instead, the type uses excellent precise wave front sensors that are guided by the laser technology that are responsible for the ultimate accuracy of the whole process. Excimer laser has been used for the process as to make the surgery a successful one. The complete surgery involves the use of measurements of the eye structure so that the installation and alteration are done precisely.

Wavefront LASIK eye surgery is perhaps very successful around the world with a few limitations though. The surgery does not produce extra ordinary results amongst people of older age groups. The microscope images scatter in them making the process an ineffective one compared to the default degree of precision provided by the surgery. As the scattering of microscopic diagrams does not let the doctor have a clear picture of what is running inside the eye, the process becomes difficult to take place as the foremost thing in this surgery is a complete observation and study of the internal eye structure of the subject being considered for the surgery.

The traditional LASIK comes with a couple of demerits as well that include a blurry vision when the light exposure is not proper of halo effect during night time. This has made them become ineffective in front of the laser guided wave front LASIK eye surgery. The process provides you with a vision as good as the original one because of the fact that this uses extremely high class technology. You come across no blurry effects as well as no halo effects even while driving through nights. Doctors who have been doing the wave front LASIK eye surgery even claim that this surgery type provides results that are even acceptable to people of older age groups for it has no comparison available in the market. Though, there are a few limitations, but the concept of getting a “super vision” is pretty effective.

Wavefront Lasik Surgery has become one of the many popular surgery types that are available on the planet. Lasik took over the world of surgery some time ago and has been welcomed by the world of surgeons in a very healthy manner as this uses some of the most complicated equipment around the world and gives you the kind of result that you want. Being one of the most delicate processes medically available on the planet, the surgery is perhaps one of the most expensive ones around the world. This surgery type targets all the different delicate organs around your body.

All the different types of Lasik surgeries are renowned to be marketed surgeries that the patient opts by himself in order to get better results. This surgery type tends to render way better results than the other types commercially available on the planet. The doctor sells the surgery to you compared to all the other essential surgeries that are more like a necessity. This surgery is an option for many of the patients but has remarkable results overall. The target of this surgery is eye for most of the time and people opt this in order to improve their eye sight. At times, you have the option to have a complete vision once you undergo a wave front Lasik surgery. This is because a lot of technical machine based assistance is involved in the process to make it the most accurate one.

Here is how the process goes. First of all, the patient’s eye is monitored using some very high tech machines. A three dimensional examination is taken after which your eye is being drawn on graphs that are also three dimensional using the best and the most precise technology available. This gives an accurate image of the whole eye structure that is keenly observed and a final three dimensional image is drawn. These images are used in the final phase of your eye operation in order to get the most accurate results. In case of eye sight enhancement, the cornea is placed at the exact spot using this very technology.

The Wavefront LASIK surgery gets you perfect vision, though at a high price. The prior reason to this is the use of wave front measurement system that is renowned to be the most accurate systems around the world. It gives you with accuracy that no other system is said to provide therefore getting your delicate organs sorted out at the right place. No other surgery is this delicate in terms of process yet not even accurate.

A LASIK at the first place gets the complete information about your eye structure and the way it deals with a beam of light producing an image of the cornea for eyesight surgeries. This information is developed into 3-dimensional map of all the abnormalities that exist in your eye. The defects are all closely monitored. The laser is then guided accordingly to get the best out of the surgery and alter the structure as to produce the most accurate image on the cornea.

Wave front guided LASIK is also termed as Wave front LASIK surgery or customized LASIK surgery. This surgery type is perhaps the most precise and the accurate surgery type available in the market. The surgery is not a must to the vision disturbed people instead this is the type of surgery that is being marketed by surgeons from around the world in order to improve your sight or to remove any defects from the process thereof.

The wave front guided LASIK surgery is a combination of LASIK surgery, an ophthalmologist applies a distinct yet different correction into the eye, the installation of which is being controlled by the computer completely to make it as accurate as possible and giving extremely accurate results eventually. 

The type does not use the traditional type of LASIK surgery where the correction to the focusing power of the cornea is being made. Laser guided wave front sensors are used in the whole process adding absolute level accuracy to the process. The type of laser used in the whole process of Wave front LASIK surgery is the Excimer laser. Special measurements of the eye structure are taken prior to the surgery itself.

The ultimate goal of spending around $2500 is to achieve the perfect eye that gives optically accurate results when exposed to different situations around in the daily life. The final result partially depends on the success of the physician observing the lacking inside the eye as well as providing the perfect remedy to them. The healing processes are also considered in the whole unit therefore giving the best possible result. One should try and consult a specialized doctor for the process so that the money does not go in vain. The accuracy from the doctor is one of the many prime factors that need to be considered in the whole process.

The process though has some limitations when it comes to the older patients where the scattering from microscope play significant role in outrunning the potential benefits that wave front LASIK can bring them with. Therefore, old aged individuals are requested not to expect their vision turning to perfect through LASIK. They are advised not to dream about “super vision” as the corrected form is called.

The surgeons still claim that patients even from the old age group are satisfied from this surgery type then any of the other methods available in the market as the technique used by this is still way more comprehensive than the earlier types. They also claim that with the precision that they provide, one can easily get rid of all the blurry effects as well as the halo effects that one might come across after having gone through a traditional LASIK.

The results have been remarkably good for quite some time now and that is the reason why the United States Air Force has described wave front guided LASIK to be giving excellent results as compared to everything else in the market. This is probably because the technology being used in the whole process has no match and a competition in terms of improved method might take long before coming to the surgery world.

Lasik surgery is one of the many renowned surgeries into the market these days. This surgery uses high tech equipments to be performed and costs a little too much compared to other surgeries. This surgery type is made in accordance with the very delicate organs found inside the body of a human being. The most frequently targeted organ is eye and Lasik surgery is used to deal with all the vision related issues that need surgery to be treated with.

Lasik further has many types, one of them is the wave front Lasik or the customized Lasik as popularly known in the medicine world. Lasik surgery is the type of surgery that is being marketed by doctors around the world and the selection of going this surgery is purely a patient’s selection. Custom Lasik is the most expensive of all the types of Lasik being performed in the world today. The type of Lasik uses three dimensional graph of one’s eye that is being generated by other machines in order to carry out the experiment in more controlled and precise environment. The whole blueprint of your eye structure is being taken up as to the see the ways in which the eye produces the final image. The surgery type uses this graph to reshape the front part of the eye known as the cornea producing the image at the right place.

The wave front measurement system is one of the most precise systems available in the world of surgery. This provides absolute accuracy. Being the most expensive of all, the LASIK surgery can easily get you a perfect vision that is not possible through a tradition LASIK surgery using blades or any of the other vision correctness treatment.

Laser system is being used in the whole process as described therefore the victim needs to be qualified under the FDA guidelines before your doctor suggest a wave front LASIK for you. The process might include a complete examination of your eye to create the best possible and the most accurate print of your eye structures. The custom laser system is brought into consideration before the surgery takes place. Apart from the machinery, the object is analyzed in terms of cornea thickness in case the patient has a mild to moderately high degree of vision defects. These defects could be any of the Myopia, Hyperopia and Astigmatism.

The first process done is that your eye’s ability to focus a beam of light us measured with a custom LASIK. The wave front technology is therefore used to create a 3-D map of all the abnormalities that comes into the way of your vision causing the defect. All the image processing parts of your eye are closely observed to have a clear idea. The information in the map guides the laser accordingly in the customized manner that eventually results into the reshaping of the cornea or any other structure within the eye to remove the defect from your eye and give you the perfect vision.

Lasik prices and Lasik itself is of a great concern to people from all around the world as this surgery type has brought in a revolution amongst the scope of medicine and surgery. Vision is an issue that millions of people around the globe might have come across in their past as well as there would still be people who would get affected in their later part of life.

Market has remarkable difference between the rates of LASIK and the average could not be calculated with that precision as it can be done now as many voluntary organizations have taken the jobs of at least keeping an eye on the swinging prices. Based on a market review, special quarterly reports are being generated as to keep people aware of the market rates so that they don’t pay too much for the surgery.

Lasik is being used for three purposes primarily being vision correction, simple eye surgery and laser guided eye surgery. The average cost of LASIK for all these is different as the level of complexity is different in all three of them mainly.

The vision correction procedure is all based in LASIK laser mainly as this is the only way that could be used to reach to the targets in a sensitive organ like your eye. A single price is usually quoted for the whole process that costs you around $ 2200. This cost includes all the miscellaneous expenditures that might occur in the correction of your eye sight.The second type of LASIK surgery is the one that involves use of blades in it. There is less use of technology in this one so this one is way more affordable than the other two types. The blade LASIK costs around $ 1800 on an average, costing $ 400 less than the laser correction one. This is also reasonable because of the fact that the wave front analysis is not done in this type of surgery leaving all on the expertise of the doctor.The laser guided LASIK or the one known as Bladeless LASIK is the one that costs you even more than this.

This is because the object is carefully examined and a wave front map is generated completely and then a laser guided flap is used in all the surgery process that might occur. The technology being used in this surgery is way more than the other two types raising the average cost to around $ 2400. The price difference is justified as this uses the most sophisticated of the technologies present around the globe making the operation more successful and risk free.The LASIK adds that run on the television that state a price of $ 299-499 are misleading giving improper information and misguiding the people perhaps. There might be a very few of the people out there who could possibly demand a LASIK that cheap in case they have a real minor issue with their vision.The average cost of LASIK has not raised much for the last two years unlike the rise that it was made between 2006-08. The prices have sustained well over the last two year despite the economic hike that persist for quite some time.

Before going to LASIK surgery or even prior to planning a surgery of this type, Money is one the most important factors. When you go to make any deal, affordability is one of the most important factors that you need to consider. As LASIK surgery is a microsurgery and that too, primarily on eyes. The technology that it uses along with the level of perfection and precision it demands cost a little beyond the affording limits. If you can’t afford what the surgeon has demanded, the best way is to stop thinking about LASIK and start considering other forms of surgeries. In this case, don’t make a mistake by choosing the wrong doctor instead who is not experienced with LASIK as you might risk your body completely. If something goes wrong after compromising on high price, you probably could come up with an issue that is irreversible.

The prior consideration should again be the quality of the surgeon and not the price for anyone who charges more isn’t necessarily a good doctor, and anyone who charges you less isn’t necessarily a poor one.

There different types of LASIK surgeries even and the cost of them differ significantly from one to another. These refractive surgeries differ in terms of cost because of the fact that different use different technologies and wave fronts. Some of these are expensive while others are affordable. A technological comparison would show that completely laser LASIK known as the All-Laser LASIK is found to be more expensive than the other types namely PRK, LASEK, Epi-Lasik and NearVisionCK as they are all mechanical LASIKS compared to the earlier discussed computerized one. There even payment plans that provide you security for the rest of your life and ensure that surgery would be made free in case of any issue at the later part of your life. These cost a lot more than the normal one.

There are adds running on the media marking the price of $ 299

that is pretty impractical and anyone who responds to the add is disappointed by the ground realities that differ by a considerable degree. One need to understand that the price could never be this low as the expertise involved in the process is way more than one could possibly expect.

Lasik is the type of surgery that is selected by the surgeon instead and it is kind of marketed to you in a way that your surgeon sells it to you in your issue. Try opting for the deal when you think that the doctor is credible and the LASIK that he is selling you is exactly what you want.

Once you are paying the price, you need  to keep this thing in mind that the perfect choice amongst options is what you actually want. It is not a normal accessory like your glasses that you can replace instead this is way more complex than that and no one would possibly wish to follow the $ 299 add and to play with vision in the very bizarre manner.

 All you are required to do at the first place is to look for the right surgery and consider price as the secondary factor as your vision matters way more than the price that you are going to pay. Opt for a quality doctor for the job whom you can count upon and consider financial matters as secondary.

LASIK surgery is one of the many renowned surgery types around the world. Because of the fact that LASIK surgery provides more precision and better results, the type is used in organs that demand absolute care and proper attention while they are being dealt with. The major target organs include eye primarily as it is perhaps one of the most delicate organs in the body. LASIK laser surgery takes place when it comes to eyes to ensure better and accurate results as well as better productivity.

Undergone the surgery process, one might come across the many possible side effects that come along with the process. These side effects might be the temporary ones or the long termed ones. It depends on the immune system of one individual compared to the other that sets the risk of being vulnerable to all the possible side effects. The side effects might occur in one individual while the other may adapt to the situation making no difference to the overall state.

 In the beginning, the subject might feel mild discomfort after being moved through the LASIK bladeless surgery in the starting two to three days. This might prolong to a maximum of one week. Apart from the pain, you might come across the tearing effect in your eye. The subject might see red or pink spots on the white regions in your eyes that would possibly cause itching. As the organ needs to set down completely after the surgery, therefore, the subject undergone surgery would possibly have his vision hazy or blurry on occasion. It also gives a dry sensation to the eyes in contrast to the wet feeling that normally persists. The first month after LASIK surgery would give you added problems during night time by worsening your vision with lights and you might see the halo effect around lights making it really hard to drive through nights.As most of the side effects start vanishing pretty soon, one needs not to worry until they don’t disappear for quite some time. After which the consultant surgeon should be reported.

Parallel to the temporary side effects, there are a couple of long term ones as well. The only major long term side effect of LASIK eye surgery is that you might lose a part of your vision in the whole process. The rest of the whole range of side effects can be treated well with proper care and better surveillance.

Amongst the complete patient range, there are a very few of them who get their complete vision restored yet causing issues with visibility in artificial light. They have issues looking at light sources during night time. The halo effects, glaring effect or double vision is what they come up with during night time or while in fog where the contrast ration naturally provided is low.

 Another of the long term side effect is a continuity of the temporary side effect. As a result of the surgery, the eye does not produce tears to wash the organ naturally therefore making it dry overall. The dryness causes itching and discomfort to your eye eventually. A drop therapy needs to be done in this case.
