I have -5.5 in both eyes. I am 22 and I use contract lenses daily. Is lasik laser operation good? What are the side effects in the long run?

LASIK is safe. Your prescription and age are right for lasik. Lasik surgery is safe and effective with minimal side effects if patients are screened properly. You should have a lasik evaluation which will determine if you are a good candidate or not. If your corneas are too thin, pupils too large or have irregularly shaped corneas you are not a good candidate.
