Abstract :
Purpose: To demonstrate the value and safety of laser in situ keratomileusis (LASIK) in the correction of ametropia in eyes with previous successful scleral buckling surgery done for rhegmatogenous retinal detachment (RD).Patients and Methods: Ten eyes of ten patients who had previous successful scleral buckling surgery for the treatment of rhegmatogenous retinal detachment were candidates for refractive correction of postoperative ametropia using excimer laser. Laser in situ keratomileusis (LASIK) was performed using Schwind excimer laser- ISIRIS system. And LASIK flaps were created using the automated micokeratome Moria M2. Uncorrected (UCVA) and best corrected visual acuity, ultrasound pachymetry before and 6 months after LASIK, and development of intraoperative or postoperative complications were measured.Results: In all patients, the UCVA improved and the myopic spherical equivalent decreased after the procedure. The mean ultrasonic pachymetry after LASIK was 432 μm± 23.1 (SD) (range 380 to 505 μm). No patient had difficulties with LASIK or serious postoperative complications. One patient with previous epithelial scraping had postoperative epithelial defects that had completely resolved without residual effects.Conclusion: To correct ametropia in the form of myopia or myopic astigmatism in eyes with a previous scleral buckle, LASIK was a feasible and relatively safe procedure.
