Investigating vitreous degeneration after cataract surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study examines the incidence of complete posterior vitreous degeneration following phacoemulsification, a common cataract surgery. It utilizes wide-field optical coherence tomography (OCT) to detect and classify posterior vitreous detachment (PVD) and its complications more effectively than previous methods. By identifying risk factors associated with abnormal PVD, the study aims to enhance prevention strategies for related disorders. The research will involve cataract patients over 50 years old who have not previously shown complete PVD.
