Summary

This study looked at different methods to measure how well an artificial lens stays centered and aligned in the eye after cataract surgery. It involved 53 adults who had already received a specific type of lens implant. The goal was to compare measurement techniques, not to test a new treatment.

Who is studied

Participants eligible for the study must be 22 years of age or older and have received a refractive or diffractive nontoric TECNIS IOL in at least one eye. Additionally, they must be at least three months post-operative in the designated study eye. The Investigator should choose the eye without any clinically significant medical conditions that may interfere with the evaluation of IOL tilt and decentration using the testing methods specified in this study. If both eyes meet the eligibility criteria, the right eye will be designated as the study eye.
