Abstract

We measured the horizontal and vertical diameter of the cornea, axial length and lens power in 314 patients who were admitted for cataract extraction. The data was analyzed by Minicomputer (honewel level 6 Model 57, U.S.A.) Cobal language. The results were as follows; 1) The average of the horizontal corneal diameter was 11.47 mm in the males and 11.17 mm in the females, and difference of the horizontal corneal diameter was 0.30 mm between both sexes. The average of the vertical corneal diameter was 10.80 mm in the males and 10.48 mm in the females and the difference of the vertical corneal diameter was 0.32 mm between both sexes. The horizontal and vertical corneal diameter in the males was loger than that of the females in adult. 2) The coeneal diameter was longest in the 41~50 years old group in male and 51~60 yaers old group in femele. The horizontal and vertical corneal diameter showed a tendency to decrease with age in adult. 3) We obtained significant changes statistically in that the cornea diameter showed atendency to increase as axial length increased in adult. 4) The corneal diameter was longest in the 15.01~16.00 Diopter group in lens power and the cornea diameter showed a tendency to decrease as lens power increased.
