Laser in situ keratomileusis enhancement after radial keratotomy

PURPOSE: To present results of laser in situ keratomileusis (LASIK) enhance ment after radial keratotomy (RK). METHODS: Sixteen eyes of 10 patients were treated with LASIK for residual m yopia and hyperopia after RK. Mean preoperative spherical equivalent refrac tion was -3.14 +/- 3.04 D (range, -6.675 to +6.00 D). Best spectacle-correc ted visual acuity was 20/20 in 9 eyes, 20/25 in 6 eyes, and 20/30 in 1 eye. Uncorrected visual acuity was better than 20/40 in only 2 eyes. Patients w ere followed at 1 day, 1 week, 1, 3, and 6 months, and 1 year. Mean follow- up was 8.3 months (range, 1 to 17 mo). RESULTS: All eyes received one LASIK enhancement. Mean final spherical equi valent refraction was +0.16 +/- 0.68 D (range, -1.00 to +1.75 D). No eyes e xperienced any visual loss. Five eyes gained 1 line of best spectacle-corre cted visual acuity. Uncorrected visual acuity was 20/20 in 9 eyes, 20/25 in 6 eyes, and 20/30 in 1 eye. Two eyes of one patient had the previous RK in cisions open. CONCLUSION: LASIK was an effective treatment for correction of residual myo pia and hyperopia after RK.
