Cataract Clinical Trial
Official title:
Comparing the Effect of Depth of Focus Difference in High Myopic Patients Receiving Cataract Operations Between 3D Visualization System and Traditional Optical Microscope.
This study aims to investigate the impact of depth of field differences between the use of the 3D imaging system (NGENUITY® 3D Visualization System, Alcon, TX, USA) and conventional optical microscope in cataract surgery for highly myopic patients on intraoperative parameters and outcomes.
The objective of this study is to compare the surgical outcomes and parameters between cataract surgeries performed using the NGENUITY® 3D Visualization System (Alcon, TX, USA), a 3D imaging system, and the current standard binocular microscope in highly myopic patients. The focus is on evaluating the differences in depth of field and their impact on intraoperative parameters and outcomes. This prospective randomized controlled trial aims to enroll patients with both high myopia and cataracts requiring surgical intervention. Participants will be randomly assigned to undergo cataract surgery using the current standard binocular microscope (control group) or the NGENUITY® 3D Visualization System (Alcon, TX, USA) (study group). The study will compare intraoperative parameters, surgical outcomes, and the incidence of potential complications, including the frequency of microscope adjustments during surgery, total distance of adjustments during surgery, distance needed to achieve clear focus from the corneal surface to the posterior capsule, surgical duration, cumulative ultrasound energy during surgery, and occurrence of surgical complications. ;
