title: Residual corneal astigmatism after perforating keratoplasty.
abstract: A statistical analysis was made of post-operative astigmatism after perforating keratoplasty in subjects with various corneal diseases. A total of 100 cases were analyzed on discharge (25th day) and 6 months after surgery. The degree of astigmatism and its time course was assessed, and its effect on post-operative visual acuity was investigated, including any changes resulting from removal of the continuous suture. Mean astigmatism values were 4 dioptres on discharge and 4.2 dioptres after 6 months. No statistically significant relation was found between degree of astimatism and recovery of visual acuity.
