Corneal Eccentricity.

In the past, the human eye was said to be spherical, the cornea circular, and corneal astigmitism unexplained. However, new technology and careful measurements show that the eyeball is oblate and the cornea elliptical. The object of this paper is to introduce my study which evaluated 30 normal corneas using computer assisted videokeratography. My purpose is to compare data performed in the past that will support my clinical data regarding corneal eccentricity. Using color coded topographic maps for each cornea, my goal is to find an average corneal eccentricity (e) and correlated that figure to each patients corneal toricity.
