LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.
All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea.
In an everyday situation, poor vision is just an inconvenience. The modern world has provided us with lots of easy solutions: glasses and contact lenses are readily available. Personally, I have required vision correction since I was 7 years old. I can barely remember a time when reaching for my glasses was not the first thing I did each morning.
In a disaster scenario, though, bad vision could be a terrible handicap. What if something happened to your glasses? What if you lost a contact or had no solution to rinse them? Would you be able to function without vision correction? Have you ever stopped to consider how impaired youd be? Could you shoot, evade, hunt, or defend yourself? How would you ever replace these items?

The first step to having LASIK surgery is to choose an ophthalmologist.

Glasses or contact lenses are used to compensate for the eye's refractive error by bending light rays in a way that complements the eye's specific refractive error. In contrast, LASIK and other forms of refractive surgery are intended to correct the eye's refractive error to reduce the need for other visual aids.
