Anatomy of cornea and ocular surface

Mittanamalli S Sridhar. Indian J Ophthalmol. 2018 Feb.

Abstract

Important functions of cornea in the eye include protecting the structures inside the eye, contributing to the refractive power of the eye, and focusing light rays on the retina with minimum scatter and optical degradation. Considerable advances have taken place in understanding the organization of collagen in the corneal stroma and its clinical significance. In this review, the structure and function of various components of cornea and ocular surface are presented.
