title: [Predictive factors in radial keratotomy. Analysis of results].
abstract: Prospective evaluation of radial keratotomy was conducted on 300 surgeries. Group A recovered low myopia within -0.75 to -3.00 diopters (D) and group B extended from -3.25 to -9.00 D. Before surgery the mean spherical equivalent in the first group was -2.29 D and in the second -4.81 D. After 12 months, the average change in spherical equivalent was 2.19 D in the A group and 4.08 in the B group. After one year, the mean uncorrected visual acuity was above 20/25 in all cases of the first group and ranged from 20/30 to 20/25 in the second one. A discussion of the different predictive factors is presented as well as a statistical approach to each parameter.
