With over 96% of patients achieving 20/20 vision or better, LASIK is a safe, convenient, and inexpensive way to improve eye sight. Approved by the FDA since 1996, it is widely considered the best way to improve eyesight. Conditions such as nearsightedness, farsightedness and astigmatism can be treated with LASIK.
A very small percentage of patients may need a touch up or enhancement after initial surgery. Also, there is a condition called presbyopia that is a normal middle-age related loss of eye sight that requires some patients to still need reading glasses.
Your eyesight consists of the cornea (front part of the eye), focusing light on the retina (back part of the eye). When the cornea is misshapen or eyeball is longer or shorter than normal, poor eyesight ensues. Using an excimer laser, the LASIK procedure is an extremely accurate and precise process of reshaping the cornea.
