Purpose
Astigmatism significantly compromises visual quality (VA) in myopic patients, yet the efficacy of non-toric Implantable Collamer Lens (ICL) in patients with moderate to high astigmatism (>1D) remains unexplored. This study aims to evaluate the efficacy, safety, and stability of non-toric ICL V4c implantation in astigmatic patients, providing evidence to guide clinical decision-making.
Setting
A single-center retrospective study.
Methods
This study included 59 eyes of 34 astigmatic patients (with astigmatism greater than 1.0 diopters [D]) who underwent non-toric ICL V4c implantation between 2021 and 2024 at a single center. Refractive parameters, uncorrected distance visual acuity (UDVA), and corrected distance visual acuity (CDVA) were collected preoperatively and at 1 day, 1 month, 3 months, 6 months, and 12 months postoperatively.
Results
The study included 34 patients (59 eyes),with a mean age of 27 years (range:17-51),of whom 67% were female.Preoperative cylinder measurements averaged -1.85 ± 0.65D,while postoperative measurements were -1.78 ± 0.68D,showing no statistically significant difference. The mean sphere increased from -10.19D preoperatively to 0.23D at 1 month postoperatively.Furthermore, 96% of eyes achieved spherical refraction within ±1.0 D, and 72% were within ±0.5 D,with refractive stability maintained over the 12-month follow-up.At 1month postoperatively, 98% of eyes gained at least one line compared to preoperative CDVA without astigmatism.When evaluated against preoperative CDVA with astigmatism, 62.2% of eyes achieved an improvement of at least one line.
Conclusions
Non-toric ICL V4c implantation is an effective and safe option for patients with moderate to high astigmatism, resulting in significant improvements in both refractive and visual outcomes.
