Visual Adaptation and Quality of Life After Different IOL Implantation Strategies
China264 participantsStarted 2025-03-01
Plain-language summary
This longitudinal observational study aims to evaluate long-term visual adaptation trajectories, optical quality, and patient-reported outcomes in age-related cataract patients following bilateral implantation of multifocal or mix-and-match intraocular lenses (IOLs). Patients will be followed up longitudinally after surgery to systematically assess visual performance and quality of life.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age 18 years or older with age-related cataract requiring bilateral phacoemulsification and intraocular lens (IOL) implantation
* Corneal astigmatism less than 0.75 D
* Good general health and willing to complete all postoperative follow-up visits
* Signed written informed consent
Exclusion Criteria:
* Previous ocular surgery or ocular trauma
* Coexisting ocular diseases affecting visual potential, such as corneal opacity, glaucoma, macular degeneration, or diabetic retinopathy
* Intraoperative or postoperative complications (e.g., posterior capsule rupture)
* Systemic diseases that may interfere with visual outcomes or follow-up compliance
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
