Refractive
Surgery
Lasik stands for Laser In Situ Keratomileusis, which is a mouthful but which is the refractive surgery of choice for most individuals. Like PRK ( Photorefractive Keratectomy), the older popular procedure for correcting nearsightedness and astigmatism, Lasik uses a cool, ultraviolet laser beam to reshape the cornea. In PRK, the outermost epithelial layer of the cornea is removed prior to using the laser to reshape the surface of the eye and then a bandage contact lens is worn while the epithelium regrows over the newly shaped cornea (which usually takes about three days). In Lasik, an instrument called a microkeratome or an Intralase laser beam is used to create a thin flap in the cornea, leaving the epithelium intact. The flap is folded back out of the way, the laser reshapes the exposed corneal tissue, and then the flap is folded back to its original position. Within a matter of minutes the flap seals itself without need of a bandage or patch. Custom Lasik is the newest generation of laser correction. Using a sophisticated wavefront analysis of your eyes, the minute, individual optical aberrations that are different from one individual to the next are mapped out and programmed directly into the laser for correction. Custom Lasik has the potential to give you a better quality of vision than can be achieved by glasses, contact lenses or earlier generations of refractive surgery. Both the custom and conventional lasik procedures have a high success rate and minimal complications. Custom Lasik is a bit more costly and requires more involvement of the surgeon before the computer guided laser takes over. Lasik enjoys a rapid visual recovery and provides an accurate correction for many prescriptions. Refractive surgeries like PRK and Lasik are intended to correct your vision at that point in time, but they will not stop conditions like nearsightedness and astigmatism from progressing. The ideal candidate is someone whose prescription is relatively stable. It is however possible to retreat the eye at a later point in time if the vision does worsen. Most of the laser centers we work with have implemented a "Lifetime Commitment Program" which promises to re-treat your eyes free of charge should it become necessary. If you are interested in laser vision correction for yourself, let us know when you schedule your next exam. We'll be glad to evaluate your suitability as a candidate for Lasik, Phakic IOL's or whatever current refractive technology would be most appropriate for your eyes..
