Comparing Vision and Satisfaction After Cataract Surgery Using Six Different Intraocular Lenses Including Five Enhanced Depth of Focus and One Standard Lens

What this Trial Is About

This research aims to compare the vision outcomes and patient satisfaction of six different types of artificial lenses intraocular lenses or IOLs implanted during cataract surgery. It focuses on how well these lenses help people see at far, middle, and near distances, how satisfied patients are with their vision after surgery, and how often glasses are still needed. The study addresses an important need for better intermediate vision following cataract surgery by evaluating modern extended depth-of-focus lenses against a standard monofocal lens. Participants will have cataract surgery in both eyes, 1 to 2 weeks apart, receiving one of six lens types TECNIS Eyhance, AcrySof IQ Vivity, LuxSmart, Rayner EMV, Eyecryl SERT, or the standard monofocal CT ASPHINA 409M lens. The procedure is standardized with a single experienced surgeon performing all implantations. Each lens uses a different optical design to potentially improve vision at various distances, especially intermediate vision important for daily tasks. During the study, participants undergo vision tests at multiple distances, contrast sensitivity tests under different lighting conditions, and fill out questionnaires about their vision quality and daily activities. Follow-up visits occur at 1 day, 1 week, 1 month, and 3 months after surgery to monitor visual performance, patient satisfaction, lens stability, and any complications. Researchers measure outcomes such as distance-corrected intermediate visual acuity, binocular defocus curve, contrast sensitivity, and vision-related quality of life to help guide lens selection for future patients.
