Dr., Sağlık Bakanlığı Göz Hastalıkları, Kayseri, Türkiye Purpose: To compare the corneal endothelial protective effects of two different dispersive viscoelastics used in phacoemulsifi cation surgery (sodium hyaluronate % 3 [Endocoat®] and chondroitin sulfate % 4.0 - sodium hyaluronate % 3.0 combination [Viscoat®]).
Material and methods: The study was comprised of two groups of patients : Both groups 1 and 2 were composed of 40 eyes of 40 patients on which Endocoat and Viscoat were used during phacoemulsifi cation, respectively. Endothelial cell count (ECC) of all patients was measured at postoperative days 1 and 30. The changes in ECC at postoperative day 30 from baseline were compared between the two groups.
Results: The preoperative mean ECCs were 2397±410 cells/mm2 in the Viscoat group and 2325±410 cells/mm2 in the Endocoat group. The mean ECC decreased by 297 cells/mm2 (a 12.3 % loss) in the Viscoat group and by 343 cells/mm2(a 14.7 % loss) in the Endocoat group at postoperative day 30, as is illustrated.There was no statistically signifi cant difference in ECC change at postoperative day 30 between the two groups( p=0.21).
Conclusion: The corneal endothelial protective effects of sodium hyaluronate % 3 (EndocoatR) and the combination of chondroitin sulfate 4.0% and sodium hyaluronate % 3.0 (ViscoatR) during the phacoemulsifi cation were similar.
