STATISTICAL STUDY OF THE RESULTS OF RADIAL KERATOTOMY

The statistical study of 384 R.K. performed by the same surgeon shows that in 82 % of R.K., preoperative myopia was between - 1.5 to - 6 diopters and in 77.5 % of R.K., postoperative refraction was between - 1 to + 1. The 90 % confidence interval was between - 2 to + 1 for all preoperative myopias and was the best when preoperative myopia was between - 0.5 to - 3 diopters (- 1 to + 1 D.). The study of the stability and security shows that this surgical technique is stable and gives a good security.
