	The cornea is the clear outer layer of the eye through which you can see the [[Iris]] and [[Pupil]]. It has an [[index of refraction]] of 1.376, and a curved outer surface, contributing to the [[refractive state]] of the eye. The Cornea is about 80% of the eye's internal lens power. If you have [[LASIK]] or [[PRK]] surgery it thins the cornea to change your refractive state.		The cornea is the clear outer layer of the eye through which you can see the [[Iris]] and [[Pupil]].
