Abstract Details

Purpose:

To compare the effect of SMILE cap-thickness in myopic and myopic-astigmatic eyes

Setting:

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

Methods:

Contralateral consecutive case series. Inclusion criteria: myopic and myopic astigmatic bilateral SMILE-treatment with either 100 µm or 120 µm cap thickness. Sidecut, lenticule diameter, lenticule sidecut, laser spot spacing, and pulse energy were identical in contralateral eyes. Target refraction was emmetropia in all cases. Comparison of refractive outcomes, visual acuity, and adverse events at 3 months.

Results:

Fifty-one patients were included. At 3 months, mean spherical equivalent refraction was 0.01+/-0.3 D (range: -0.5 to +0.75D) for 100µm and -0.05+/-0.31 D (range: -1 to +0.75 D) for 120µm. Mean cylinder was -0.25+/-0.26D (range: 0 to -1D) and -0.3+/-0.27D (range: 0 to -1D) for 100µm and 120µm, respectively. Mean uncorrected distance visual acuity (UDVA) was 1.08 (decimal scale) and 1.1 for 100µm and 120µm, respectively. Mean efficacy index was 0.81 and 0.8 for 100µm and 120µm, respectively. Mean safety index was 0.91 and 0.91 for 100µm and 120µm, respectively.

Conclusions:

We found equally good visual and refractive outcomes with either 100 µm or 120 µm cap-thickness.
