Abstract Details


To report clinical experience including visual outcome and complications of small incision lenticule extraction to correct astigmatism or myopic astigmatism more than 3D eyes.


Nunemiso Eye Clinic, Seoul, Korea.


64 eyes of 47 patients underwent small incision lenticule extraction(SMILE) to correct their astigmatism or myopic astigmatism and were followed up more than 3 months. 29 patients were men and 18 were women. Mean age of the all patients was 29.3 years old and the range of corneal thickness was 482~661microns. We made 6.0~6.5mm diameter lenticule and it was extracted through 2.0~4.0mm side-cut incision by using forceps. Estimated postoperative corneal thickness including 100~120micron cap thickness was at least 400microns. We checked uncorrected distance visual acuity(UDVA), manifest refraction and ocular condition after 1day, 1week, and 3months postoperatively.


Preoperative mean astigmatism was 3.37±0.48D (3.00 ~ 4.25D) and preoperative mean spherical equivalent was -5.52±1.66D (-2.00 ~ -8.19D). Postoperative mean UDVA was 0.94±0.21(POD 1day), 1.02±0.22(POD 1week), 1.03±0.22(POD 1months), 1.04±0.20 (POD 3months). 73% achieved UDVA 1.0 or better on the last follow up. Postop. mean spherical equivalent was -0.25±0.51D postop. mean astigmatism was -1.09±0.45D. 82% had a refractive outcome between ±0.5D of attempted refraction and 92% between ±1.0D. Suction loss occurred in one eye. There was no serious postoperative complication like keratectasia, corneal opacity.


Small incision lenticule extraction is effective and safe vision correction procedure in treating high astigmatism more than 3 diopters. Visual recovery was quick and there was no vision threatening postoperative complication.
