Surgical results of second-attempt radial keratotomy.
The safety, efficacy, and stability of second-attempt radial keratotomy were evaluated in 20 eyes of 12 patients from September 1, 1982, to August 31, 1983. The average amount of refractive error change was 1.89 diopters with 1.38 diopters of corneal curvature flattening. The effect of the second-attempt operation was about 60% that of the first-attempt operation. No significant surgical complications were observed in this study.
