Only patients with at least one-year follow-up were included. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell density (ECD), and pIOL vault were analyzed 1, 3, 6, and 12 months after surgery. Intraoperative and postoperative events were recorded in all cases.Results: The study included 30 eyes from 15 patients. The mean patient age was 25.8 ±  3 years. The spherical equivalent of manifest refraction was − 11.47 ±  4.38 D preoperatively and − 0.44 ±  0.55 D postoperatively. The preoperative CDVA was 0.17 ±  0.12 logMAR. The postoperative UDVA was 0.053 ± 0.11 logMAR (min: − 0.17 and max: 0.2) and 0.019 ± 0.091 logMAR (min: − 0.17 and max: 0.2) at the end of 1 month and 6 months, respectively. At the end of the 12-month visit, the postoperative UDVA was 0.032 ± 0.094, and the safety index was 2.42. The mean ECD was 2639 cells/mm2 (min: 2389 and max: 2993 with SD: 139.53) at the preoperative visit and 2445 cells/mm2 (min: 2050 and max: 2701) at the 12-month visit (5.8% loss, p less than 0.001). ECD loss from 6 months to 12 months was not statistically significant. No significant cataract formation, significant endothelial cell loss, glaucoma, uveitis, or any other vision-threatening complication were observed.Conclusion: Based on postoperative experience, we found that RIL phakic IOLs are safe and effective for treating high myopia at short-term follow-up.Keywords: refractive intraocular lens, RIL, myopia, phakic lensSubudhi PPatro SAgarwal PKhan ZSubudhi BNRMekap CPadhi ADove Medical Pressarticlerefractive intraocular lens (ril)myopiaphakic lensOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 3681-3689 (2020)
