Abstract Details

Purpose:

To report the outcomes of SMILE for myopia with sphere up to -10.00 D and cylinder no greater than 0.50 D.

Setting:

London Vision Clinic

Methods:

This was a retrospective review of SMILE at London Vision Clinic using the VisuMax femtosecond laser (Carl Zeiss Meditec). Inclusion criteria were all eyes to have undergone SMILE for sphere up to -10.00 D and cylinder up to 0.50 D between November 2011 and December 2015. SMILE was performed using two 2-mm small incisions; one primary supero-temporally and one reserve supero-nasally. Patients were followed for 1 year after surgery and standard outcomes analysis was performed.

Results:

During the study1,049 eyes (690 patients) met the inclusion criteria. One year follow-up was available for 94% of eyes, and 3 months for the remaining 6%. Mean attempted SEQ was -4.69±1.92 D (-1.00 to -9.94 D). Mean cylinder was 0.33±0.17 D (0.00 to 0.50 D). Preop CDVA was 20/20 or better in 100% of eyes.Postop UDVA was 20/20 or better in 93% and 20/25 or better in 98% of eyes. Mean postop SEQ was -0.13±0.37 D, with 83% within ±0.50 D.There was 1 line loss CDVA in 8% of eyes,and one eye (0.1%) lost 3 lines CDVA.

Conclusions:

SMILE for spherical myopia (including cylinder up to 0.50 D) was found to achieve excellent visual and refractive outcomes. There was negligible cylinder induced by the small incisions.
