Visual outcomes after cataract and refractive procedures
Official title: Outcomes of Cataract & Refractive Procedures
Run by Vision Care Collective Limited · NCT07481487 · Data updated 2026-11-12
This project uses past clinical records to see how adults who had cataract surgery with an intraocular lens or refractive procedures fared in vision and refraction and to compare different IOLs and procedures.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older who have undergone a refractive procedure or cataract surgery with an implanted intraocular lens and can consent to pseudonymised use of their data are ideal candidates.
✕Probably not a fit
People who have not had cataract or refractive surgery, are under 18, or cannot consent to use of their data are not eligible and are unlikely to benefit.

What this trial studies
This observational database retrospectively collects pseudonymised clinical data from adult patients who underwent cataract surgery with intraocular lens implantation or refractive procedures at Vision Care Clinic Bristol. It records visual acuity and refractive outcomes over time and compares results across different IOL models and refractive techniques. No new treatments are given; analyses are performed on existing medical records after patient consent for data use. The database is intended for continuous outcome monitoring and to inform clinical choices about lenses and surgical approaches.
Why it matters
Potential benefit: If successful, the database could help surgeons and patients choose IOLs and refractive procedures that produce better vision outcomes.
How similar studies have gone: Similar retrospective registries and audits have previously identified differences in outcomes between IOL types and refractive techniques, though randomized prospective trials are less common.
