Endothelial protection (measured by vital-dye staining and computerized
planimetry) and viscoelastic retention during phacoemulsification with and
without traumatic lens implantation were assessed in a rabbit model
comparing four viscoelastics (Healon, Amvisc Plus, Occucoat, and Viscoat).
No significant differences in cell damage were noted between unoperated on
controls and groups that underwent atraumatic phacoemulsification with
viscoelastic. Cell damage after traumatic lens insertion was reduced
significantly by all four viscoelastics. Cell damage with and without
traumatic lens implantation was significantly lower when viscoelastics were
retained. Viscoat and Occucoat were significantly more likely to be
retained than Healon.
