Purpose

To evaluate the visual and refractive outcomes of central-hole Implantable Collamer Lens implantation, and its safety profile in myopia and myopic astigmatism.

Setting

Ophthalmology Department, Central Lisbon Hospital and Universitary Center, Lisbon, Portugal

Methods

Retrospective unicentric observational study of patients with Implantable Collamer Lens implantation. Main Outcome Measures 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. Safety index was 1,10±0,20. Postoperative manifest spherical equivalent was within ±0,50 D of target in 81,8% 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 14,13 mmHg postoperative was not clinically significant. Mean central vault was 524,06±185,71 μm. Two eyes underwent lens explantation due to a 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 implantation demonstrated good visual and refractive outcomes, with a favorable safety profile, for the correction of myopia and myopic astigmatism.
