In vivo imaging characterizes differences in OVD retention

In vivo confocal microscopy was used to measure the thickness of ophthalmic viscosurgical devices (OVDs) retained beneath the corneal endothelium after phacoemulsification surgery. Results are reported for six different OVDs used in surgeries performed with varying fluidics settings.

Key Points

"Not surprisingly, the dispersive agents showed greater retention than the OVDs with more cohesive properties," said V. Vinod Mootha, MD, associate professor of ophthalmology, University of Texas Southwestern Medical Center.
