An observational study in Myopia, Cataract and Pseudophakic Retinal Detachment, sponsored by Prim. Prof. Dr. Oliver Findl, MBA. Completed at 1 site in Austria. Open to participants aged 21 Years and older. Per ClinicalTrials.gov, last updated 2026-03-13.

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population.
The aim of this multicenter study is to document the presence and/or post-operative development of posterior vitreous detachment (PVD) and to assess its influence on the incidence of retinal detachment (RD) in myopes in a time period of three and five years after lens surgery.
618 eyes of patients scheduled for regular lens surgery will be included, defined by an axial length of 25.0 mm or more. To examine the vitreous status, all patients will receive a comprehensive eye examination pre-operatively, including funduscopy with assessment of a Weiss ring and optical coherence tomography (OCT). Patients will be divided into two groups, group A with pre-operative complete PVD and group B with no/partial PVD. Group A will be invited for one follow-up visit (two months post-operatively) followed up by telephone interviews at one, two, three and five years after surgery to determine occurrence of pseudophakic retinal detachment. Group B will be invited for follow-up examinations at two months, six months and one year after surgery to document occurrence of PVD (if a PVD is present at one of the follow-ups, no more visits are necessary). Two, three and five years after surgery, all patients from group B will be interviewed by telephone, as in group A, to document the occurrence of pseudophakic retinal detachment.
In the recent literature the association between the occurrence of PVD pre-/post-operative and RD after lens surgery is well documented but not described for myopic patients. The results of this multicenter study should help to tackle the problem of RD prediction in myopic patients depending on their pre-operative vitreous status, especially in the setting of refractive lens exchange.

Counted across the registry records on this site, refreshed daily.
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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
