LASIK is an acronym for Laser Assisted In-Situ Keratomileusis, which means “to reshape the cornea by using a laser.” The difference between PRK and LASIK Surgery is that PRK treats the exterior of the eye, reshaping the outside surface while LASIK Eye Surgery reshapes the cornea after a thin flap has been created on the surface of the eye.
As a result, with LASIK there is less area to heal, less risk of scarring, less risk of corneal haze, less postoperative pain, fewer postoperative medications, and vision is often improved more rapidly. Gordon-Weiss-Schanzlin Vision Institute was one of the initial centers in the United States to offer LASIK Eye Surgery.
With the LASIK Surgery procedure, a thin flap is created in the top layer of the cornea with the WaveLight® FS200 Femtosecond laser or a microkeratome, forming a “corneal cap”. The laser is then used to remove a thin layer of tissue from the cornea under the flap. The cap is then returned to its natural position, creating a healthy surface within 24 hours. This re-shaping of the cornea helps the eye focus properly, thus reducing or eliminating the need for contact lenses or eyeglasses.
No sutures are required after replacing the cap. The surface is kept dry for several minutes and is then flushed with antibiotic eye drops. An eye shield or patch is applied.
After LASIK Surgery, patients may experience moderate burning or itching in the eye. The shield is removed the morning after surgery. For many patients the vision will be greatly improved after the patch is removed, whereas for others, variable improvement will be noticed with greater improvement as the eyes continue to heal. This depends on the amount of astigmatism present at the time of surgery. Eye drops will be prescribed.
In most cases, patients are able to return to work in a matter of a few days. Most activities may be resumed almost immediately. The face however should not be placed under water for at least two weeks.
Initial findings indicate the advantages of LASIK over PRK for high myopia:
- More rapid recovery of vision.
- Significantly less discomfort.
- Significantly reduced risk of scar formation.
- More predictable result for correction of high myopia compared to surface excimer laser treatment for high myopia.
