Purpose: To compare the results of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) to correct myopia and astigmatism in eyes previously submitted to retinal detachment (RD) surgery with scleral buckle. Methods: Twenty-five eyes of 22 patients submitted to scleral buckling procedure with significant refraction changes after surgery were evaluated. Fourteen eyes of 13 patients underwent LASIK and 11 eyes of 9 patients underwent PRK. Minimum time between RD surgery and refractive surgery was 12 months. All patients were followed for at least 12 months. Results: Twelve months after surgery, mean spherical equivalent in the LASIK group changed from –6.49D preoperatively to –0.17D and mean astigmatism reduced from –1.10D to –0.23D. Spherical equivalent in the PRK group decreased from –5.35D before surgery to +0,02D and average astigmatism changed from –1.38D to –0.54D. In both groups, uncorrected visual acuity (UCVA) improved at least 4 lines in 11 eyes. Conclusions: Both LASIK and PRK were safe and effective to correct refractive error after RD surgery. Our results showed no significant difference between procedures. Further studies with more patients and long-term follow-up are advisable to better evaluate the effects of refractive surgery in patients submitted to scleral buckling procedure.
