Ultrasound check of IOL tilt 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 observational study uses ultrasound biomicroscopy to visualize the front part of the eye and assess how an implanted intraocular lens sits after phacoemulsification. The method provides high-frequency images to help identify lens tilt or decenteration and may relate findings to preoperative lens position. The study discusses factors that can contribute to tilt, such as asymmetric IOL fixation or capsular irregularities. Inclusion focuses on adults with senile cataract undergoing standard IOL implantation, while several ocular conditions and prior surgeries are excluded to reduce confounding. The goal is to characterize tilt and decentration patterns using noninvasive imaging.
