Abstract

The changes of corneal curvatures were measured in 63 cataract cases before and 2 months after cataract extraction with the aid of ophthalmometer and photo keratoscope. The change of the cornea in the vertical curvature was shown to be greater than that of horizontal curvature, in cases of conventional large corneal incision(120-170 degrees) of cataract surgery. Vertical curvature of the cornea was decreased and horizontal curvature was increased. The corneal astigmatism before and 2 months after surgery were respectively 0.67D. and 1.56D. showing the difference of 0.89D.
