title: Astigmatism analysis after radial keratotomy.
abstract: Radial keratotomy without T-cutting was performed on 245 eyes of 124 patients with 6-8 months of post-operative follow-up. The results showed that post-operatively astigmatism was increased in 74 eyes (30.2%) with the increased range from +0.50 to +3.50DC, decreased in 27 eyes (11.0%) and not changed in 144 eyes (58.8%). The main causes of astigmatic change included microperforations, irregular incisions, incisions across the central optical zone and various depths of incisions, etc.
