Nearsighted patients studied for retinal detachment risk after cataract surgery
NCT ID NCT03152747
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed 609 nearsighted adults who had lens surgery to see if a natural eye change called posterior vitreous detachment (PVD) affects their risk of retinal detachment. Participants were grouped by whether they had PVD before surgery or not, and were monitored for up to 5 years. The goal was to better predict retinal detachment risk in nearsighted patients after lens surgery.

Who is studied
Study population: target 618. The participants will be selected by the clinical investigators at several ophthalmological centres in Austria, Belgium, Spain, Norway and the Netherlands. As the study population is already scheduled for cataract surgery / refractive lens exchange, recruitment will be performed directly in these centres at the pre-assessment visits. At this visit, optical biometry is performed and patients with suitable axial eye lengths will be screened. If all inclusion and no exclusion criteria are met the patients will be asked to participate in the trial.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Minimum 21 years of age * Patients scheduled for lens surgery with an axial eye length of 25.0 mm or more * Availability, willingness, sufficient cognitive awareness to comply with examination procedures * Ability to sign informed consent Exclusion Criteria: * Patients with combined surgery (e.g. combined phacoemulsification and vitrectomy or trabeculectomy or DSAEK) * Patients with previous intraocular surgery (except any kind of laser surgery e.g. retinopexy, refractive laser surgery) * Patients with recurrent severe anterior or posterior segment inflammation or uveitis of unknown aetiology, or any disease producing an inflammatory reaction in the eye * Any ophthalmological pathology with the potential to compromise the measurements (e.g. mature/very dense cataract, fixation difficulties) * Penetrating ocular trauma * Previous history of retinal detachment * Patient is pregnant, plans to become pregnant, is lactating or has another condition associated with the fluctuation of hormones that could lead to refractive changes * Patients participating in another study
