Visual and refractive outcomes of small incision lenticule extraction for the correction of myopia: 1-year follow-up.
Bottom Line: Preoperatively, 1 week, and 1, 3, 6 and 12 months postoperatively, we assessed the safety, efficacy, predictability, stability, corneal endothelial cell loss and the adverse events of the surgery.The endothelial cell density was not significantly changed from 2804±267 cells/mm(2) preoperatively to 2743±308 cells/mm(2) 1 year postoperatively (p=0.12).No vision-threatening complications occurred during the observation period.

Mentions: LogMAR CDVA was −0.15±0.07, −0.19±0.07, −0.20±0.08, −0.20±0.07 and −0.22±0.07, 1 week, and 1, 3, 6 and 12 months after surgery, respectively. We found no significant difference between preoperative CDVA and 1 year postoperative CDVA (p=0.48, Wilcoxon signed-rank test). The safety index was 0.86±0.17, 0.95±0.24, 0.97±0.21, 0.97±0.21 and 1.00±0.20, 1 week, and 1, 3, 6 and 12 months postoperatively, respectively. Thirty-three eyes (63.5%) showed no change in CDVA, eight eyes (15.4%) gained one line, while nine eyes (17.3%) lost one line and two eyes (3.8%) lost two lines 1 year postoperatively (figure 1). Although two eyes lost two lines, possibly because of a very mild interface haze formation and/or irregular astigmatism, these eyes had a CDVA of 20/20 or better.
