Abstract

The author has measured refractive error and corneal curvature in 500 eyes of 250 patients who visited the Department of Ophthalmology, Ewha Womans University Hospital, with decreased visual acuity as chief complaint, for 6 months from Sep. 1, 1984 through Feb. 28, 1985, and found the following conclusions: First, as for the means of each corneal horizontal curvature and vertical curvature, the mean of horizontal curvature was 7.7876 +/- 0.9791mm; that of vertical curvature was 7.7217 +/- 0.8527mm in right cornera, while the mean of horizontal curvature was 7.8628 +/- 0.7295mm; that of vertical curvature was 7.5986 +/- 1.2349mm in the left cornea. Second, as for the comparison of corneal curvature by sex, it was highly significant(p<0.05) that the means of each corneal horizontal curvature and vertical curvature were always larger in the case of male than that of female. Third, as for the comparison by each age group(age groups under 25 years, from 25 through 44 years, and from 45 years up respectively), there were no significant differences(0 0.05) in respective means of each corneal horizontal curvature and vertical curvature among age groups. Fourth, as the result of this study on correlation between corneal curvature and refractive error, its correlation is 0.32% to 4.66%, showing no significant correlation between them.
