Quantitative assessment of ophthalmic viscosurgical device retention using in vivo confocal microscopy.

Purpose: To develop and apply a new laboratory method for in vivo quantitative assessment of the retention of ophthalmic viscosurgical devices (OVDs) following phacoemulsification.

Setting: Department of Ophthalmology, University of Texas Southwestern Medical Center, Dallas, Texas, USA.

Methods: Studies of both eyes of New Zealand White rabbits were performed.

New classification of ophthalmic viscosurgical devices--2005.

Purpose: To revise the generally accepted classification of ophthalmic viscosurgical devices (OVDs) to include cohesion data and the new class of viscous dispersive OVDs.

Setting: York Finch Eye Associates, Toronto, Ontario, Canada, and Alcon Research Limited, Fort Worth, Texas, USA.

Methods: Pseudoplasticity and cohesion-dispersion (CDI) data of DisCoVisc (hyaluronic acid 1.
