My Cornea Thickness is 470. my Right Eye Is-4.75 and Left Eye -4.5 .Now what should i get. (Lasik / PRK / ICL) !!!!!!!!!!

Your corneas certainly are substantially thinner than
normal. LASIK would not be a good
option. If your corneal topography
is completely normal, you could have PRK surgery. There is no clear consensus on how thin a cornea can safely
be after PRK, but in my experience 400 microns has not caused any problems like
ectasia (bulging of the cornea from being left too thin after LASIK or
PRK). At 12-14 microns per diopter
of treatment (depending on laser used, and treatment zone), your ablation depth
would be 54 to 66 microns.

The ICL would be a perfectly good option, though it is a bit
more expensive and slightly more invasive. If there is ANY question as to whether your corneal
topography is normal or not, I would opt for the ICL. Otherwise, as far as which is better, both are equally good
in my opinion.

If your elevation topography is normal you may have PRK. The option of ICL is also one to consider should there be any issues with you topographic evaluation. I would, however, not advise LASIK in this circumstance. Some patient who elect for laser vision correction in the face of thin corneas will elect to combine it with collagen cross linking. This is a technology that can strengthen the cornea and thus make laser surgery safer.
