Comparing vitrectomy alone to vitrectomy with cataract removal for retinal detachment
Official title: Clinical- and Cost-effectiveness, Safety and Acceptability of Sequential Vitrectomy and Cataract Surgery vs Combined Phacovitrectomy for Rhegmatogenous Retinal Detachment: Randomised Equivalence Trial
Run by Queen's University, Belfast · NCT06997874 · Data updated 2026-11-12
This study is testing whether doing just vitrectomy or adding cataract removal helps older adults with retinal detachment see better and have fewer problems after surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 50 and older with rhegmatogenous retinal detachment who are not highly myopic and have not had previous vitreoretinal surgery.
✕Probably not a fit
Patients with established cataracts, high myopia, or those who have undergone previous vitreoretinal surgery may not benefit from this study.

What this trial studies
This clinical trial aims to determine the best surgical approach for treating rhegmatogenous retinal detachment (RRD) in adults aged 50 and older who have not previously undergone cataract surgery. It compares outcomes between patients receiving only vitrectomy and those undergoing a combined procedure of vitrectomy and cataract removal. The study will assess the effectiveness of each approach in terms of retinal reattachment and vision improvement. Participants will be monitored for complications and overall visual outcomes following their respective surgeries.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical strategies that enhance vision recovery and reduce complications for patients with retinal detachment.
How similar studies have gone: While there is limited data on combined vitrectomy and cataract surgery for RRD, previous studies suggest that vitrectomy alone is effective, making this approach a potentially novel exploration.

Inclusion Criteria: * Adults ≥50 years of age * Non-highly myopic (\< -6 diopters; ≤26.5 mm axial length) phakic RRD * Naive to previous vitreoretinal surgery * Pars plana vitrectomy is planned to repair their RRD Exclusion Criteria: * Presence of a "formed/established cataract." A "formed/established cataract" is defined as a cataract that, based on the Age-Related Eye Disease Study (AREDS) Research Group, is graded as nuclear sclerosis of \>3 and/or if there is an anterior cortical cataract and/or a subcapsular posterior cataract involving the visual axis. * Pseudophakia or aphakia * High myopia (≥ -6 diopters; \>26.5 mm axial length) * Giant retinal tear (i.e. presence of one or more retinal tears of \>3 clock hours in size) * Retinal dialysis * Inclusion in an investigational drug study * Declined consent for participation
