Abstract Details

Purpose:

Excimer laser-based refractive procedures can have less predictable results when used for correcting high myopia than when used for moderate myopia. Small incision lenticule extraction (SMILE) might overcome this weakness. However, SMILE is only FDA-approved for use in myopic eyes up to - 8 D with astigmatism of -0.5 D or less. We report outcomes of SMILE in highly and moderately myopic eyes and compare these to modern LASIK.

Setting:

Center for Refractive Surgery, Eye Department at St. Francis Hospital Muenster, Germany

Methods:

Observational consecutive case series. Inclusion criteria: attempted myopic spherical correction more than -7.75 D or -3 to -7.75 D with astigmatism -3.0 D, and corrected distance visual acuity (CDVA) of 1.0 (decimal scale) or better.

Results:

Sixty-two highly myopic and 407 moderately myopic eyes were included. At 3 months postoperatively, the highly myopic eyes had a mean spherical equivalent refraction of -0.28 ± 0.41D (range: -1.13 to +0.75D) and a mean cylinder of -0.38 ± 0.24 D (range: 0 to -1.0 D). Mean UDVA was 1.0. Mean efficacy index was 0.84. Mean safety index was 1.03. UDVA same or better than CDVA: 61 %. Astigmatism was ≤ 0.5D in 90 % and ≤ 1D in 100%. The results in the moderately myopic eyes were comparable. SMILE showed a better predictability in highly myopic corrections than LASIK.

Conclusions:

We found equally good visual and refractive outcomes after SMILE for the correction of high and of moderate myopia combined with an astigmatic correction of up to 3 D, respectively. SMILE may be a good alternative to LASIK especially for treatments of high myopia.
