I just had a consultation for lasik, and the doctor said that the right
eye is normal and can have lasik. But that the left eye has a very
slight irregular curvature. The top part of the cornea curves slightly
less than the bottom. He said that he doesn't think it's
Keratoconus, and that all tests did not alert possible Keratoconus
disease. Therefore, he recommends PRK on the left eye and Lasik
on right.
I am 31. Is it possible that I have a very early stage of Keratoconus?
How do I know for sure? Should i get prk?

We have a detailed article about keratoconus at http://www.usaeyes.org/faq/subjects/keratoconus.htm that you may find helpful.

Your doctor appears to be cautious about whether or not you have symptoms of keratoconus, however I think it would be unwise to have Lasik in the eye that does not have symptoms of keratoconus. It is rare that keratoconus affects only one eye. If one eye is suspect, then in my opinion both eyes are suspect.

Any refractive surgery that removes tissue may exacerbate keratoconus or push you from early stage or from fruste keratoconus into frank keratoconus. Your doctor may provide you all the informed consent that is necessary, but you are the one who will deal with rigid gas permeable (RGP) contacts or corneal transplant if keratoconus is present and progresses.

I suggest that you consider Intacs http://www.usaeyes.org/faq/subjects/intacs.htm instead of Lasik or PRK if you are less than 3.00 diopters myopic (nearsighted, shortsighted) and be evaluated by a corneal specialist at a teaching hospital affiliated with a university to determine if you are actually a high risk keratoconus patient or just have an unusual cornea.
