Abstract
Most patients undergoing refractive surgery have a history of soft contact lens (SCL) wear, which may influence the results of ReLEx® SMILE.
Purpose of the study was to evaluate the influence of the wearing SCL duration on the refractive results of laser correction of myopia using the ReLEx® SMILE method.
Materials and methods. A retrospective analysis of the results ReLEx® SMILE surgery in 80 patients (160 eyes) was performed. Group 1 included 12 patients (24 eyes) with less than 5 years of SCL use, Group 2 —18 patients (36 eyes) with 5–10 years of SCL use, Group 3 —19 patients (38 eyes) with more than 10 years of SCL use. Comparison group consisted on 31 patients (62 eyes) using glasses before the operation. The observation period was 6 months.
Results. The SE refraction (D) after 6 months was 0.06 ± 0.30 in the control group, 0.03 ± 0.29 in group 1, 0.21 ± 0.38 in group 2 and 0.02 ± 0.31 in group 3 (p < 0.05). Postoperative refraction of ±0.5 D from the planned refraction after 6 months was found in 87.5 % in the control group, 86.7, 77.0 and 94.7 % of cases in group 1, 2 and 3 respectively (p < 0.05). In all groups, the result of surgery was stable throughout the follow-up period, and a trend towards minimal myopic refraction was noted. The efficacy rate in the control group was 98 %, and 97 % in the group using SCL.
Conclusions. Previous use of SCL in patients with myopic refraction had no negative effect on refractive parameters and on the course of ReLEx® SMILE surgery.
