Comparing Depth of Focus Effects in Cataract Surgery for High Myopic Patients Using the NGENUITY 3D Visualization System Versus Traditional Optical Microscope

What this Trial Is About

This research aims to compare surgical outcomes and parameters between cataract surgeries performed using a new 3D imaging system called the NGENUITY4 3D Visualization System and the current standard binocular microscope in patients with high myopia. The study focuses on how differences in depth of field between these two systems affect factors during surgery and the results, including potential complications. Participants will have high myopia and significant cataracts requiring surgery. Participants will be randomly assigned to one of two groups one group will undergo cataract surgery using the standard binocular microscope, while the other group will have surgery using the Alcon NGENUITY4 3D Visualization System. During surgery with the NGENUITY system, the surgeon wears 3D glasses and views the operation on a 3D screen. Both groups receive standard cataract extraction with phacoemulsification and intraocular lens implantation. Throughout the surgery, researchers will measure how often and how far the microscope focus is adjusted, the distance needed to focus from the corneal surface to the lens capsule, total operation time, and ultrasound energy used. After surgery, participants will be followed for three months to monitor vision, eye pressure, and any complications. These assessments will occur on day 1, week 1, month 1, and month 3 after surgery to evaluate safety and effectiveness of the two visualization methods.
