ClinConnect Summary

This clinical trial is looking at a treatment called Limbal Relaxing Incisions (LRIs) to see how effective it is for correcting high astigmatism that can occur after cataract surgery (phacoemulsification). The study aims to find out if combining LRIs with glasses improves vision better than just using glasses alone.

To participate in this trial, you should be between the ages of 65 and 74 and have had cataract surgery at least a month ago. You must also have a clear cornea and have astigmatism greater than 3.0 diopters, which is a measure of how distorted your vision is. However, if you have had previous eye surgeries, experienced eye injuries, or have certain eye diseases, you may not be eligible. If you join the study, you can expect to have your vision monitored to see how well the treatment works compared to just wearing glasses. It’s an opportunity to help understand a new approach to improving vision after cataract surgery.
