Abstract Details

Purpose:

To report the outcomes of SMILE for high myopia between -9.00 and -14.00 D.

Setting:

London Vision Clinic, London, UK

Methods:

This was a prospective study (clinicaltrials.gov identifier: NCT02528123) of SMILE for high myopia using the VisuMax femtosecond laser (Carl Zeiss Meditec). Inclusion criteria were attempted spherical equivalent refraction between -9.00 and -14.00 D, cylinder up to 7.00 D, CDVA 20/40 or better, age 21 years or older, and suitable for SMILE. The sub-lenticule thickness was ≥220 µm, and the total uncut stromal thickness was ≥300 µm. Patients will be followed for 1 year. Standard outcomes analysis was performed for the most recent visit. To date, at least 3 month data was available for 137 eyes (86 patients).

Results:

Attempted SEQ was -10.40±1.03D (-9.00 to -12.99D). Mean cylinder was -1.24±0.87D (0.00 to -4.00D). Preop CDVA was 20/20 or better in 71% of eyes. Postop UDVA was 20/20 or better in 60% and 20/25 or better in 86% of eyes. Mean postop SEQ relative to the target was -0.21±0.46D (-1.25 to +1.04D), with 68% within ±0.50D. For 80 eyes with data at 3 and 12 months, mean change in SEQ was -0.09±0.34D (-0.88 to +1.13D). There was 1 line loss CDVA in 4%, and no eyes lost 2 or more lines CDVA. Contrast sensitivity was unchanged.

Conclusions:

Outcomes of SMILE for myopia above -9.00 D at 3-12 months show excellent efficacy, safety, stability, and predictability.
