Visual and refractive outcomes of small incision lenticule extraction for the correction of myopia: 1-year follow-up.

Kamiya K, Shimizu K, Igarashi A, Kobashi H - BMJ Open (2015)

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.

BMJOPEN2015008268F2: Cumulative percentages of eyes attaining specified cumulative levels of UDVA 3 months and 1 year after SMILE (CDVA, corrected distance visual acuity; SMILE, small incision lenticule extraction; UDVA, uncorrected distance visual acuity) (postop, postoperative; preop, preoperative).

Mentions: LogMAR UDVA was −0.08±0.13, −0.12±0.11, −0.13±0.13, −0.14±0.12 and −0.16±0.11, 1 week, and 1, 3, 6 and 12 months after surgery, respectively. We found a significant difference between preoperative UDVA and 1 year postoperative UDVA (p<0.001, Wilcoxon signed-rank test). The efficacy index was 0.75±0.21, 0.83±0.24, 0.84±0.25, 0.86±0.25 and 0.91±0.25, 1 week, and 1, 3, 6 and 12 months postoperatively, respectively. The cumulative percentages of eyes attaining specified cumulative levels of UDVA 1 year postoperatively are shown in figure 2. One week and 1, 3, 6 and 12 months after surgery, 100%, 100%, 100%, 100% and 100% of eyes, and 81%, 85%, 90%, 92% and 94% of eyes had a UDVA of 20/40, and of 20/20 or better, respectively.
