Anatomy of the CorneaThe cornea is a transparent dome-shaped structure covering the iris, lens, and anterior chamber (AC) of the eye. It accounts for nearly two-thirds of the total refractive power of the eye (Fig. 1.1a,...doi:10.1007/978-81-322-2818-9_1Soosan Jacob...

The cornea is a transparent outer layer that has the dual purpose of protecting the inner parts of the eye and helping to focus images that are being viewed. Behind the cornea is the iris, which is the colored part of the eye, and the pupil which is the opening at the center. The ir...

The cornea is the transparent tissue that covers the front of the eye.It forms anterior 1/6th of the outer fibrous coat of eyeball. The word cornea has come from “Kerato”. The term “Kerato” in greek means horn or shield like. Ancient Greek used to believe that cornea is derived ...
Other articles where sclera is discussed: human eye: The outermost coat: The sclera is essentially the continuation backward of the cornea, the collagen fibres of the cornea being, in effect, continuous with those of the sclera. The sclera is pierced by
anterior chamber where the cornea and iris join is known as the angle. This is comprised of several structures that make up the eye’s drainage system. The angle structures include: the outermost part of the angle, the front of the ciliary body, the trabecular meshwork, and the Canal of ...
While the primary role of the cornea is to act as a protective layer over the eye, it also has a refractive index of approximately 1.38. Note that the refractive index has no units as it is a ratio of the speed of light in a vacuum compared to the speed of light in a specialized ...
