3D visualization system and standard operating microscope for ease of visualization and surgeon comfort during phacoemulsification surgery.

Purpose: To compare the ease of visualization and comfort of the surgeon during phacoemulsification surgery using NGENUITY® 3D (NG) visualization system and standard operating microscope (SOM).

Methods: In this prospective, randomized, single-blind, single-center study, patients undergoing phacoemulsification surgery by one of the five surgeons were randomly assigned to two groups based on the visualization modality-NG and SOM. Ease of visualization and comfort of the surgeon was assessed using a 27-parameter in-house Surgeon Comfort Score questionnaire.
