Abstract Details

Purpose:

The ReLex® SMILE procedure is considered as safe, predictable and effective in treating myopia and myopic astigmatism. Nevertheless, the presence of residual refractive errors may require further enhancements. In 2015, we have describe a new technique of enhancement: SubCap – LE. Today, we present you our results of the 16 eyes.

Setting:

Single refractive surgery center.

Methods:

13 patients (mean age at surgery 32.5 years ± 8.35(SD)) were treated by SMILE in the first surgery. The presence of residual refractive errors in 16 eyes may require an enhancement by SubCap – LE. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), topography, aberrometry, keratometry, pachymetry, contrast sensitivity, OSI were assessed preoperatively as well as 1 day, 1 week, 1 month, 3 months, 6 months postoperatively

Results:

The mean residual spherical equivalent was -0.86 ± 0.45 diopters (D) after ReLex SMILE. Snellen (20/) uncorrected distance visual acuity (UDVA), at 1 and 6 months postoperatively SubCap-LE, were, respectively, 20.16 ± 2.18 and 20.44 ± 5.99. At 6 months postoperatively, UDVA was better than or equal to 20/20 in 85.71 % of eyes. The efficacy index was 1.73 ± 0.52. 73.33 % of eyes were within ± 0.50 D of the intended refractive target. One eye lost 2 Snellen lines. The safety index was 1.17 ± 0.12. No significant changes of aberrations were detected among the 1-month or 6-month follow-ups postoperatively.

Conclusions:

This study demonstrated the feasibility and efficacy of enhancement after SMILE procedure by SubCap-LE technique for blurred vision after myopia correction. This method retains all initial SMILE advantages. A dedicated software must be developed in order to determine a more definite profile and increase the safety and the predictability of the technique
