The big results of Lasik surgery have been improved by research adding the latest methods, such as Wavefront technology. This kind of technology gives a Lasik physician the great ability to see and accurately map even slight variations in the surface of the eye. This gives the Lasik physician the ability to accurately tailor a Lasik procedure to the individual, and result in even clearer vision.

Behind Wavefront technology was a great concept originally developed by astronomers, in order to indicate if a mirror or a lens had slight imperfections in it. It is trully  important in astronomy to get close perfect optics in order to clearly see the small light sources million of miles away in the universe. In the 1970s a sensor was created to electronically check these surfaces, and a type of this sensor is now used in the Wavefront guided Lasik operations.

The principal idea to use this sensor or to apply this technique, to the field of ophthalmology and later to the specific area of Lasik vision correction, has begun in Germany. The physician Josef Bille began this by using the sensor in his practice, and this maked others to refine the sensor and how it is used and to apply it to Lasik technology. In the 90′ they improved sensor, with greater accuracy and speed, was announced to the Lasik laser manufacturers. This allowed the companies that manufacture the Lasik equipment to develop tools using the Wavefront concept for each of their own laser systems.

The FDA was the first that approved the first Wavefront guided Lasik vision correction system for general use. Initially, the Wavefront sensor makes a map of the eye’s imperfections, and this map is sent to the laser that is used in the Lasik vision correction portion of the procedure. This allows for precise eye alteration in order for Lasik to present a verry good vision correction possible.

The Wavefront technology used in Lasik can be described very easy at an informal level. A small, flat sheet of light is passed through the eye, reflected off of the retina, and passed back through the eye and is captured by the Wavefront machine. If the eyes were perfect, the light would return as a flat sheet and be captured that way by the Lasik machine. Anyway, imperfections changes the way that the light returns, and this is detected by the Wavefront part of the Lasik process.

A number of these small, flat sheets of light are sent into each eye from various directions and the results returned generated a three dimensional map of the eye to be used in the Lasik vision correction procedure. In addition to the usual known problems of astigmatism, nearsightedness and farsightedness, there are more than 70 other patterns that are known and can possibly be corrected.

All this information generated by the Lasik sensor is converted by software into a set of directions to be carried out by the Lasik excimer laser. Ask your own doctor about this exciting advance in Lasik vision correction, and see if this procedure is the one right for you!
