Outcomes of small incision lenticule extraction with dual-incisions in myopic patients

Abstract

Purpose: To assess the stability, safety, predictability, and efficacy of small incision lenticule extraction (SMILE) with dual-incisions in myopic patients. Setting: Ebsar Eye center, Benha, Qalyopia, Egypt. Design: Single-center, retrospective, COHORT study. Patients and Methods: The study was conducted as a retrospective non-comparative analysis of the records of 105 eyes of 53 patients treated by the SMILE with a dual-incisions technique for a mean spherical myopic error of −5.05 ± 1.93 D (range: −1.38 to −9.0 D) with or without astigmatism and the mean astigmatism of −0.90 ± 0.83 D. The mean LogMAR corrected distance visual acuity (CDVA) was −0.04 ± 0.07. Results: One month after surgery, the mean refractive error was −0.03 ± 0.56 D (range: 0.88 to −1.50 D), and the mean postoperative astigmatism was 0.20 ± 0.31 D. The mean LogMAR UDVA was 0.07 ± 0.18 in the last follow-up visit, 12 months after surgery. At the end of the follow-up period, approximately 91.43% of patients had unchanged CDVA or gained one or more lines, 8.57% lost one line of CDVA, and 0.0% lost 2 lines. Conclusion: SMILE with dual-incisions is effective and safe, with a stable and predictable outcome for correction of myopia and myopic astigmatism.
