Description
Background To assess the early clinical outcomes of toric implantable collamer lenses (toric ICL™, STAAR Surgical) for the correction of high myopic astigmatism with keratoconus. Methods This study evaluated 27 eyes of 14 patients with spherical equivalents of -10.11±2.46 D (mean ± standard deviation) and astigmatism of -3.03±1.58 D who underwent toric ICL implantation for mild keratoconus. Before, and 1, 3 and 6 months after surgery, we assessed the safety, efficacy, predictability, stability, and adverse events of the surgery. Results LogMAR uncorrected visual acuity (UCVA) and LogMAR best spectacle-corrected visual acuity (BSCVA) were -0.09±0.16 and -0.15±0.09 respectively, 6 months after surgery. The safety and efficacy indices were 1.12± 0.18 and 1.01±0.25. At 6 months, 85% and 96% of the eyes were within ±0.5 and ±1.0 D respectively of the targeted correction. Manifest refraction changes of 0.00± 0.35 D occurred from 1 week to 6 months. No visionthreatening complications occurred during the observation period. Conclusions Toric ICL implantation was good in all measures of safety, efficacy, predictability, and stability for the correction of spherical and cylindrical errors in eyes with early keratoconus throughout the 6-month follow-up period, suggesting its viability as a surgical option for the treatment of such eyes.
