title: Radial keratotomy in high myopia: an evaluation of one technique.
abstract: Ninety-one consecutive eyes of 53 patients with refractive errors of -6.00 to -11.50 diopters (D) spherical equivalent (mean, -7.48 D) underwent radial keratotomy with redeepening and astigmatic incisions. All eyes were examined at six months, and 65.9% had one year of follow-up (mean follow-up, 11.65 months). In retrospective analysis of this group, 78% of patients had greater than or equal to 20/40 uncorrected visual acuity at six months with 76% at one year. In 59.3% of patients they were with 1.0D of emmetropia at six months with 56.7% at one year. Overcorrections (greater than +1.00D) with 11.1% at six months and 13.3% at one year. Undercorrections (greater than -1.00D) were 29.6% at six months and 30% at one year. Four patients lost two lines of Snellen visual acuity.
