Abstract

Purpose: To assess the efficacy of the Toric Implantable Collamer Lens (Toric ICL) to treat moderate to high myopic astigmatism.
Methods: Toric ICL was implanted in 77 eyes of 40 patients with myopia (spherical equivalent [SE] between 3.5 and 18.5 diopters [D]) and astigmatism between 1 and 6 D. The patients were followed up for at least 3 months. Uncorrected visual acuity (UCVA), refraction, best spectacle-corrected visual acuity (BSCVA), adverse events, and postoperative complications were evaluated.
Results: At 3months postoperatively, the proportion of eyes with 1.0 or better UCVA (56 eyes out of 77 eyes, 72.7%) was significantly greater than the proportion of eyes with preoperative 1.0 or better BSCVA (38 eyes out of 77 eyes, 49.4%). The mean manifest refractive cylinder dropped from 2.78D (±1.05) at baseline to 0.35D (±0.34) postoperatively, an 87.4% decrease in astigmatism. Mean manifest refraction SE (MRSE) improved from -9.93D (±2.66) preoperatively to 0.15D (±0.33) postoperatively. A total of 96.1% of eyes were predicted accurately to within ±0.75D of predicted MRSE. Mean improvement in BSCVA was 0.79lines; there were no eyes that lost two lines of BSCVA after 3 months postoperatively.
Conclusions: The results support the efficacy and predictability of Toric ICL implantation to treat moderate to high myopic astigmatism.
