Brief Summary
Digital 3D microscopes require less light and may be more comfortable for patients requiring cataract surgery under topical anesthesia compared to conventional microscopes. To date, no studies have evaluated the comfort and subjective visual sensations related to the light of the 3D digital microscope in cataract surgery patients. The purpose of this study is to evaluate the effectiveness of the Ngenuity 3D digital operating system (Alcon, Fort Worth, TX) compared to conventional microscopes on the comfort and subjective visual sensations related to of patients undergoing initial cataract surgery under topical anesthesia (pure or combined with intravenous sedation).
