LASIK (laser-assisted in situ keratomileusis) is a safe, reliable and painless way to improve vision and reduce or eliminate the need to wear glasses or contact lenses. LASIK changes the way light is bent, or refracted, as it passes through the cornea so that it focuses properly on the retina and objects can be seen clearly.
During the procedure, a device called a microkeratome cuts a thin flap in the surface of the cornea. Patients are given anesthesia so they can’t feel the instruments. The flap is then lifted and an excimer laser beam reshapes the cornea’s curvature to improve vision.
The entire procedure takes only 10-15 minutes for both eyes, and patients are often ready to leave within an hour. The flap heals on its own within a few days with no need for stitches.
A common complaint after surgery is sensitivity to light, but this will subside. Antibiotic eye drops will be prescribed for a few days, along with any other post-operative instructions. Full recovery takes a few weeks.
VISX™’s CustomVue procedure combines the most advanced technologies of the WaveFront and STAR S4 Excimer Laser systems for high-definition, high-accuracy LASIK vision correction. CustomVue makes it possible to perform customized refractive surgeries using information gathered from your own eyes. This allows us to correct the very specific refractive errors that obscure each patient’s vision so you can enjoy the best post-operative vision quality possible. Other benefits of the CustomVue process include faster treatment time and no need to dilate the pupils.
PRK or photorefractive keratectomy is one of the safest and most time-tested laser vision correction procedures available. Like LASIK, it reshapes the cornea to improve vision.
In PRK the surgeon uses an excimer laser to vaporize a small amount from the top of the cornea. LASIK, by contrast, cuts a deep flap in the cornea using a sharp microkeratome blade. This weakens the cornea, makes it difficult to replace the flap in precisely the right place, and can cause other complications including flap irregularity, epithelial ingrowth and corneal ectasia. PRK avoids these risks.
