• Does Corneal Thickness determine if you are a good candidate for LASIK?


    Question:

    I have been told that to be a good candidate for LASIK that your cornea has to be thick enough. Is it true that the U.S. Food and Drug Administration regulates that you must have a minimum of 250 microns of corneal tissue after the procedure? If you will have more than that, is it enough or cutting it too close if you will have 310 left? When should you consider PRK?


    Answer:

    The FDA does not regulate the corneal thickness and curvature of a potential LASIK patient. That being said, most surgeons want at least 270 microns and 310 would be wonderful. If your surgeon has any doubt, PRK is a perfectly acceptable option that will get you a great result with a bit of extra healing time.
