Abstract Details

Purpose:

The purpose of this study was to compare the refractive outcomes of small incision lenticule extraction (SMILE) in high myopia patients with those of mild to moderate myopia patients.

Setting:

Onnuri Eye Clinic, Jeonju, korea

Methods:

This study included 183 eyes of 92 myopic patients treated with SMILE using a Visumax 500-kHz femtosecond laser. Treated eyes were divided into two groups, according to the preoperative spherical equivalent (SE): mild to moderate myopia (A group, <−6.0 D) and high myopia (B group, ≥−6.0 D). Follow-up visits were at 1 day, 1 week, and 1, 3, 6, and 12 months. The outcome measures included uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (BDVA), postoperative SE, efficacy index, safety index, and predictability.

Results:

No differences were observed between −0.13 ± 0.38 D in the A group and −0.24 ± 0.35 D in the B group 12 months postoperatively (p = 0.18). The efficacy index was 1.04 ± 0.19 in the A group and 0.99 ± 0.19 in the B group. The safety index was 1.27 ± 0.17 for the A group and 1.24 ± 0.17 for the B group. The efficacy and safety index were not significantly different between the two groups 12 months postoperatively (p = 0.141 and p = 0.307, respectively).

Conclusions:

This study showed that SMILE is effective and safe for correcting high myopia, as well as mild to moderate myopia
