Clinical trials

The main purpose of this investigation is to support safety and performance assessment of the investigational device with a focus on optimizing the IOL constants based on refractive outcomes.

This is a prospective, Phase IV, post-approval observational study evaluating postoperative outcomes in patients with a history of myopic corneal laser vision correction (LVC) undergoing bilateral cataract surgery with implantation of the CT LUCIA 621P intraocular lens (IOL). Up to 30 subjects (60 eyes) will be enrolled across up to three U.S. investigational sites. The study will assess visual and refractive outcomes, including biometry, manifest refraction, and patient-reported visual function over a 3-month follow-up period.

The goal of this clinical trial is to collect information on vision outcomes in people aged 45 to 65 who have difficulty seeing clearly at near distances due to aging (a condition called presbyopia). All participants will receive the same treatment: laser eye surgery with the PRESBYOND method using the MEL 90 excimer laser. The main questions this study aims to answer are: * How well do patients see at distance, intermediate, and near after treatment? * How satisfied are patients with their vision after surgery? Participants will: * Attend seven visits over six months (before surgery and after surgery at 1 day, 1 week, 1 month, 3 months, and 6 months) * Undergo laser eye surgery with PRESBYOND * Complete vision tests and questionnaires about their experience There is no comparison group in this study.
