Purpose: To compare the effects of two different dispersive viscoelastics used in phacoemulsification surgery(sodium hyaluronate % 3 [Endocoat®] and chondroitin sulfate 4.0% sodium hyaluronate 3.0% combination [Viscoat®])on corneal endothelium. Material & Methods: We divided the patients into two groups: Group 1 composed of 20 eyes of 20 patients; Endocoat was used during phacoemulsification. Group 2 composed of 20 eyes of 20 patients; Viscoat was used during phacoemulsification. Endothelial cell count (ECC) of all patients is measured at postoperative 1st and 30th days. The change in ECC at postoperative 30th day from baseline was compared between two groups. Results: Preoperative mean ECC was 2350 cells/mm2 in the Viscoat group and 2299 cells/mm2 in the Endocoat group. The mean ECC decreased by 311 cells/mm2(a 9.4% loss) in the Viscoatgroup and by 331 cells/mm2 (a 14% loss) in the Endocoat group at postoperative 30th day.There was no statistically significant difference in ECC change from preoperative values at postoperative 30th day between the two groups (p=0.105). Conclusion: The protective effect of sodium hyaluronate 3% (EndocoatR) and the combination of chondroitin sulfate 4.0% and sodium hyaluronate 3.0% (ViscoatR) on corneal endothelium during phacoemulsification is similar.
