Abstract

BACKGROUND: Myopia, an optical condition in which the eye is unable to focus on distant objects due to a non-accommodating lens, has spurred centuries of efforts toward correction and potential cure. In this study, we aim to compare the efficacy, and safety of myopia correction through the implantation of 2 types of pIOLs: the Foldable iris-fixated (Veriflex) AC pIOL and the posterior phakic ICL. Our focus is on patients presenting moderate to high myopia, divided into two distinct groups for comprehensive evaluation.
METHODS: This prospective randomized comparative study included 46 patients (80 eyes) diagnosed with myopia. The patients were randomly divided into two groups:  Group A: 40 eyes from 24 patients who implant the Veriflex IOL.  Group B: This group included 40 eyes from 24 patients who implant the ICL.
RESULTS: After a 3-year follow-up, in Group A, the mean pre-operative spherical error (SE) was -12.3 ± 1.5 diopters for the Veriflex, while in Group B, it was -16.9 ± 3.6 diopters for the ICL. The mean postoperative  BCVA at 3 years was 0.71 ± 0.03 logMAR for Veriflex and 0.83 ± 0.13 logMAR for ICL.
CONCLUSION: Both Veriflex and ICL phakic intraocular lenses were found to be, effective, predictable and safe with a low rate of  complications. They offered rapid visual rehabilitation and long-term stability for patients with myopia.
