Protective effect of viscoelastics against retina lipid peroxidation.
Viscoelastics or ophthalmic viscosurgical devices are routinely used during anterior segment surgery and also in posterior segment surgery. Studies of the harmful effects of phacoemulsification on corneal endothelial cells suggest that much of this damage is mediated by free radicals. In this study, we compare the possible effects against lipid peroxidation in the retina of three different viscoelastic substances: Viscoat, Healon and Visiol. Herein we demonstrate for the first time that viscoelastics are effective to protect the retina against lipid peroxidation, as can be seen by the slight increase of malondialdehyde in the homogenates incubated with viscoelastic exposed to light and to a temperature of 37 degrees C when compared with the control homogenates.
