Are you currently wearing contacts or eye-glasses?
Once your eyesight is weak to the point that you are using lenses or glasses then only way is to go for laser surgery. Nothing else can get rid of those lenses or glasses.
What if you have astigmatism in one eye? Is Laser recommended then?
One of these days we may have a discussion on astigmatism and what are some of the ways it can be corrected. I do not believe laser is one of them, for a laser to make a cut in the eye, it has to have a specific dimensions. Maybe more research needs to be done and solutions of what can qualify as possible remedies for astigmatism eyes.
