Comparing Two Types of Trifocal Toric Intraocular Lenses for Cataract Surgery A Multicenter Study on Vision Outcomes and Safety

What this Trial Is About

Researchers are evaluating two commercially available trifocal toric intraocular lenses to compare their clinical outcomes and patient satisfaction in people undergoing cataract surgery. The main goal is to compare the distance-corrected intermediate visual acuity provided by these lenses. Additionally, the study aims to assess and compare the safety of the two trifocal toric intraocular lenses designed to correct astigmatism and improve vision at near, intermediate, and distance ranges. Participants will be randomly assigned to receive one of two types of trifocal toric intraocular lenses Optiflex TRIO or AcrySof IQ PanOptix. Both lenses are single-piece, posterior chamber foldable intraocular lenses with advanced aspheric optics and a trifocal design intended to reduce dependence on glasses. The Optiflex TRIO features a refractive-diffractive trifocal toric optic with a square edge design, while the AcrySof IQ PanOptix has a diffractive trifocal optic with a toric component. Each participant will receive one of these lenses based on randomization during cataract surgery. During the study, participants will be monitored for visual acuity outcomes, focusing on binocular distance-corrected intermediate vision at six months after lens implantation. Researchers will also track patient satisfaction and safety throughout the study period. The study includes preoperative assessments such as corneal topography or keratometry to measure astigmatism and will involve follow-ups to evaluate visual performance and any adverse effects. The total duration of participation varies but includes at least a six-month follow-up for outcome measurement.
