Laser vision correction has been routinely performed in the United States since approved by the FDA in 1995. To date, over eight million procedures have been performed in the U.S.
Laser vision correction gives one the opportunity to function with no reliance or a greatly reduced need to rely on glasses or contact lenses. This provides a freedom that those of us who do not wear glasses take for granted. Those who have had the procedure are thrilled to be able to wake up in the morning and see.
Lasik is a procedure that takes only about 15 minutes to perform. Afterwards, there is a three to four hour period where the eyes may sting, tear or feel irritated. By the next day, most are able to function normally, including driving, although the quality of vision continues to improve over the following several weeks. PRK is an alternative laser vision correction procedure that has visual results equivalent to Lasik but takes much longer to regain best vision. The advantage of PRK is that it can be used with thin corneas where Lasik would be riskier and also with eyes that have previously undergone radial keratotomy.
People commonly and appropriately ask, “What are the risks of Lasik?” Fortunately, the risks are very small. I performed the procedure on my wife several years ago. She still sees 20/20 and loves it. However, there are risks and they include things that are potentially serious. One of the most serious risks of Lasik is causing a condition called corneal ectasia. This is a condition similar to keratoconus where progressive warping of the cornea causes blurred vision. Several factors have been identified which place a person at risk, including the thickness and shape of the cornea. A thin cornea and a cornea that has an irregular shape are felt to be more risky for Lasik. The Randleman risk factor score system has been found to be very helpful in identifying those patients which may be at increased risk for developing corneal ectasia after Lasik. Other risks of Lasik include displacement of the corneal flap after surgery. This rarely occurs but can be corrected. Other common occurrences after Lasik include transient dry eye symptoms which can also be treated.
There is a risk of not meeting a patient’s expectations when there has not been enough discussion prior to the procedure. When selecting a surgeon for laser vision correction, it is important that one be chosen who will honestly communicate answers to your questions in order to help you make an informed decision.
