Abstract |
In 24 pterygium patients, the corneal curvature was measured before and after surgical removal. The norizontal curvature increased more than 0.5 D in 66.7% of cases on the 2 to 3 weeks postoperatively. The vertical curvature, however, showed no marked tendency to changes, and only 25% of cases showed more than 0.5 D increase on the 2 to 3 weeks postoperatively. As the pterygium invades the cornea extensively, the horizontal corneal curvature increased more markedly. |
