Q: Hi, I am considering verisyse eye surgery since my vision is about -10.00. Can you tell me anything with regard to the safefy of this procedure compared to lasik. Also, is there discomfort during and after the procedure. Thanks, William A: The safety profile is different for Verisyse than for laser vision correction. Whereas most of the problems with laser vision correction would occur during or shortly after the procedure, the Verisyse patient might experience cataracts or problems with the endothelium several years later. These percentages, however, are very small. Andrew Caster, MD www.castervision.com

Q:  Hello, What is life expectancy of a good sight after the procedure? Are there any reapet surgeries in the future or it is a one time deal? i am nearsighted at 8.5 , I am 43 years old, some asstigmatism. will i need reading glasses, what should i expect? Thank you very much. Stella A:  Most people will maintain their distance correction for most of their lives. Approximately 5 of the patients will have a change in their distance vision and could have further treatment in the future. Lasik is not correcting the near vision, so unless you have monovision treatment, then you will need reading glasses when you get older. Andrew Caster, MD www.castervision.com
