Summary

This study observed 5000 cataract surgery patients to see if using a special handpiece (Active Sentry) makes the procedure safer. The handpiece helps control pressure inside the eye during surgery, which may reduce the amount of energy needed and lower the risk of complications. The goal was to collect real-world data on how well this technology works.
