Study Comparing Visual Results of Synthesis Plus and Synthesis Plus Toric Lenses in Adults Over 50 Undergoing Cataract Surgery

What this Trial Is About

Researchers are comparing visual outcomes after implanting two types of intraocular lenses IOLs called Synthesis Plus and Synthesis Plus Toric in adults aged 50 and older undergoing cataract surgery. This study aims to determine if the distance-corrected intermediate visual acuity at 66 cm with the Synthesis Plus Toric is not worse than with the Synthesis Plus lens. The study focuses on patients with cataracts who may or may not have pre-existing astigmatism. Participants receive either the Synthesis Plus Toric IOL, designed for patients with pre-existing astigmatism, or the Synthesis Plus IOL for those with little or no astigmatism. Both lenses are implanted during bilateral cataract surgery. The study includes follow-up assessments at one month after surgery to evaluate vision and lens performance. During the study, participants will undergo various eye exams including measurements of visual acuity at different distances, refraction tests, and assessments of lens rotation and complications. Researchers also collect subjective feedback on the quality of vision. The main outcome measured is the intermediate visual acuity at 66 cm one month after surgery. The study is conducted at a single center and is sponsored by Cutting Edge SAS.
