Endothelial Cell Loss Following Cataract Surgery Using Continuous Curvilinear Capsulorhexis or Precision Pulse Capsulotomy.

Purpose: To compare endothelial cell density (ECD), percentage of hexagonal cells (%Hex) and coefficient of variation (CV) in cell size following lens cataract surgery with phacoemulsification performed using Continuous Curvilinear Capsulorhexis (CCC) or Precision Pulse Capsulotomy (PPC).

Patients And Methods: Sixty-seven subjects were randomly assigned to undergo lens cataract removal with the capsulotomy step performed using either CCC or PPC. Specular microscopy images were obtained pre-operatively, 1 month and 3 months after surgery.

Precision pulse capsulotomy: performance metrics and utility in routine and complex cases.

Purpose: To evaluate precision pulse capsulotomy (PPC) performance.

Setting: University and private practice in the United States and South Korea.

Design: Multicenter retrospective analysis.

Classifying the severity of corneal ulcers by using the "1, 2, 3" rule.

Purpose: To propose and define the "1, 2, 3" rule as a system of categorizing the severity of bacterial keratitis and to determine its value in predicting the likelihood of visual loss after healing of bacterial corneal infection.

Methods: Seventy patients were evaluated for infectious corneal ulcers by 2 cornea subspecialists (J.D.
