Immediate versus delayed bilateral cataract surgery in France

Official title: Medico-economic Evaluation of Immediately Sequential Bilateral Cataract Surgery Compared With Delayed Sequential Cataract Surgery in France: a Multicenter Randomized Controlled Trial

Run by Fondation Ophtalmologique Adolphe de Rothschild · NCT06737562 · Data updated 2026-11-12

This study will test whether doing cataract surgery on both eyes the same day is as safe and cost-effective as doing the two operations on separate days for adults in France with cataracts in both eyes.

Is this trial a fit for you?

Likely a good fit

Adults in France with bilateral cataracts scheduled for outpatient cataract surgery under local anesthesia who speak French, have a caregiver available, and do not have the listed ocular risk factors are ideal candidates.

Probably not a fit

Patients with high-risk ocular features (for example keratoconus, extreme axial length, prior corneal surgery), active ocular infection, need for general anesthesia, or combined eye procedures are unlikely to receive benefit from same-day bilateral surgery.

What this trial studies

This interventional medico-economic trial compares immediate sequential bilateral cataract surgery (both eyes operated the same day) with delayed sequential bilateral cataract surgery (operations separated by weeks) in adult outpatients in France. Eligible participants are adults scheduled for non-combined cataract surgery under local anesthesia who can speak French, have a caregiver available on the day of surgery and the day after, and are resident in France. The study will collect data on healthcare costs, postoperative complications including refractive outcomes and endophthalmitis, and visual/refractive results over the postoperative period. Procedures are performed at multiple French ophthalmology centers following contemporary intraoperative standards and ISBCS guidance.

Why it matters

Potential benefit: If successful, this approach could shorten the treatment timeline, reduce travel and healthcare costs, and make recovery more convenient for patients with bilateral cataracts.

How similar studies have gone: Previous reports and the ISBCS guidance since 2009 indicate same-day bilateral cataract surgery can be safe and cost-saving in carefully selected patients, although adoption varies by region.
