3D Visualization System in Highly Myopic Cataract Operation
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.

| Summary | 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. |
| Who can participate | Inclusion Criteria: 1. High myopia (axial length of 26 millimeters or more). 2. Presence of clinically significant age-related nuclear cataract requiring surgery, assessed using the International Classification System for Cataract (Lens Opacities Classification System III, LOC III), with a graded score indicating nuclear cataract (LOC III NC/NO grade 3-5). 3. Participants must be 20 years of age or older. Exclusion Criteria: 1. The target eye has undergone vitrectomy surgery. 2. The target eye has undergone corneal refractive surgery. 3. Presence of corneal diseases such as corneal dystrophy, corneal trauma, corneal scarring, corneal ulcers, or clinically significant corneal softening that significantly affects the clarity of cataract surgery. 4. Complicated cataracts with features such as |
