Abstract

Purpose: To assess the safety and efficacy of excimer laser in situ keratomileusis (LASIK) to correct hyperopic shift following radial keratotomy (RK). Setting: Ophthalmic Health Center, Tel Aviv, Israel. Methods: The study comprised 15 eyes of 12 patients who had uneventful RK and subsequently developed a hyperopic shift. Laser in situ keratomileusis was performed using the Chiron Automated Corneal Shaper and the Nidek EC-5000 excimer laser with 5.5 mm central and 7.5 mm peripheral ablation zones. The corneal flap was 160/μm in thickness and 8.5 mm in diameter. The refractive correction corresponded to the patients' refractive errors. Results: The mean time after RK was 10.46 years ± 2.21 (SD) and the mean follow-up after LASIK, 7.3 months (range 1 to 42 months). The mean spherical equivalent refraction was corrected from +3.08 ± 1.02 diopters (D) to -0.16 ± 0.73 D after LASIK. At the last examination, 12 eyes (80%) had a refractive error within ± 1.00 D of emmetropia and an uncorrected visual acuity of 20/40 or better. No wound dehiscence, epithelial ingrowth, or other significant complication developed in any eye. Conclusions: Early postoperative results of the correction by LASIK of a hyperopic shift after RK are encouraging, but long-term studies of a larger population group are required to evaluate the method's clinical value.
