Q: I suffered a traumatic injury to one eye when I was 7 (now 45), resulting in blindness in that eye. Am myopic with a slight degree of astigmatsim in the other eye; correction is with a gas-permeable contact lens. Your self evaluation indicates that I could be a candidate for LASIK or LASIK-type procedure. Understandably, only having one eye to play with, I am very interested in risk. What do you think? A: I do not recommend Lasik or other elective surgery for anyone with only one ggod eye. Even though the risk of serious problems are exceedingly low, in my opinion it is best not to perform laser vision correction. Andrew Caster, MD Beverly Hills, CA www.castervision.com
