BACKGROUND: Implantable collamer lens (ICL) implantation has gained popularity as a surgical option for the correction of high myopia. This study aimed to evaluate the visual outcomes, patient satisfaction, and safety of ICL implantation by combining objective and subjective parameters for a comprehensive assessment.
METHODS: This prospective, interventional study included 67 eyes from 37 patients who underwent ICL implantation. Visual acuity, refractive outcomes, anterior chamber depth, ICL vault, endothelial cell density, intraocular pressure, and patient satisfaction using the Visual Function Questionnaire-25 (VFQ-25) were assessed preoperatively and at various postoperative time points up to 12 months.
RESULTS: At 12 months postoperatively, the mean uncorrected distance visual acuity improved to 0.10 ± 0.08 LogMAR, and the mean corrected distance visual acuity improved to 0.04 ± 0.05 LogMAR. The mean spherical equivalent decreased from -10.57 ± 2.22 D preoperatively to -0.10 ± 0.25 D, with 95.5% of eyes within ±0.50 D of the target refraction. The mean ICL vault was stable at 625 ± 80 μm, and no significant endothelial cell loss or complications were observed. The mean composite VFQ-25 score improved significantly from 72.87 ± 11.23 preoperatively to 93.39 ± 4.68 at 12 months postoperatively (P < 0.001).
CONCLUSION: This study demonstrates that ICL implantation is a safe, effective, and predictable option for the correction of high myopia, providing excellent visual outcomes, refractive stability, and significant improvements in patient satisfaction and quality of life. The combination of objective and subjective parameters provides a comprehensive assessment of surgical success and patient-reported outcomes.
