Radial keratotomy: analysis of efficacy and predictability in 1,058 consecutive cases. Part II: Predictability

Effectiveness and predictability of anterior radial keratotomy to correct myopia and/or astigmatism were evaluated in 1,058 consecutive surgeries. The surgical technique, results, and comparison to other series are detailed in Part I. In this paper, a retrospective study for predicting the change in refraction of eyes having radial keratotomy with and without astigmatism incisions, statistically derived predictors accounted for 72.9% of the variations in outcome.
