Abstract

INTRODUCTION: To evaluate the short-term visual and refractive outcomes of V4c-V5 implantable collamer lens implantation, and its safety profile in myopia and myopic astigmatism correction.
METHODS: Retrospective unicentric observational study of patients with Implantable collamer lens implantation. Main outcome measures at 6 months were safety, efficacy, predictability, endothelial cell count loss, intraocular pressure variation and central vault. Adverse effects and complications were assessed.
RESULTS: Eighty-five eyes of 48 patients were included in the study. Postoperative uncorrected distance visual acuity was 0.05±0.11, with an efficacy index of 1.03±0.22; the safety index was 1.10±0.20. Postoperative manifest spherical equivalent was within ±0.50 D of intended target in 8.8% of eyes, and within ±1.00 D in 94.5% of eyes. Mean endothelial cell density loss was 2.34%±11.43%. Despite being statistically significant, the increase in intraocular pressure of preoperative 12.82 to 14.3 mmHg postoperative was not clinically significant. Mean central vault was 524.06±185.71 μm. Two eyes underwent lens explantation due to high vault and postoperative inflammation, and one toric lens was exchanged due to significant axis misalignment. No cases of pupillary block, chronic hypertension, cataract or lens opacity were reported.
CONCLUSION: Implantable collamer lens V4c-V5 implantation demonstrated good visual and refractive outcomes, with a favorable safety profile, for the correction of myopia and myopic astigmatism.
