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.

Phase retardation and corneal sublayer thickness repeatability using ultrahigh-resolution polarization-sensitive OCT.

Purpose: To assess phase retardation and corneal sublayer thickness repeatability using ultrahigh-resolution polarization-sensitive optical coherence tomography (PS-OCT).

Setting: Narayana Nethralaya Eye Hospital, Bangalore.

Design: Observational.

Unique corneal tomography features of allergic eye disease identified by OCT imaging and artificial intelligence.

The purpose of this study was to assess unique corneal tomographic parameters of allergic eye disease (AED) using optical coherence tomography (OCT) and artificial intelligence (AI). A total of 57 eyes diagnosed with AED were included. The curvature and aberrations of the air-epithelium (A-E) and epithelium-Bowman's layer (E-B) interfaces were calculated.
