Abstract

Abstract: : Purpose: To evaluate hyperopic laser in situ keratomileusis (H-LASIK) for induced hyperopia post-radial keratotomy (RK). Methods: H-LASIK was performed in 72 eyes of 47 patients, who had previously undergone RK. Mean follow - up was 10.22 4.66 years after RK. It is reported the mean refractive error, in spherical equivalent (SE), uncorrected visual acuity (UCVA) and best spectacle corrected visual acuity (BSCVA) before and after H-LASIK procedure. Safety was also analyzed with a mean of 13.47 8.83 months follow-up. Results: Mean preoperative SE was +3.33 1.94D. Postoperatively mean SE was -0.57 1.21D. 66.7% of eyes (n=48) were between 1.0D of emmetropia, and 87.5% of eyes within 2.0D. Preoperative BSCVA was 20/20 in 56.94% of eyes (n=41) and 20/40 or better in 100% (n=72). Postoperative BSCVA was 20/20 in 58.33% of eyes (n=42) and 20/40 or better in 97.22% (n=70). Preoperative UCVA was <=20/40 in 65 cases (90.27%). In the postoperative it was 20/20 in 17 cases (23.61%), ≷=20/40 in 45 cases (62.5%). Eight eyes (11.11%) lost 2 or more Snellen lines due to epithelial ingrowth in the interface, difuse lamellar keratites (DLK), induced astigmatism and nuclear scleroses. One of the eyes with DLK also presented epithelial ingrowth and flap necrosis. Eleven eyes(15.27%) lost 1 line and 51 eyes (70.83%) maintained or gained Snellen lines. There was no intraoperative complication besides incision opening (n=8) while lifting the flap, with no further complication to the patient. Those patients did not loose any Snellen line of their BSCVA. Conclusion: H-LASIK can be successfully used to correct residual refractive errors after radial keratotomy.
