Purpose: To compare the efficacy and intraoperative characteristics of DisCoVisc with those of Hyal 2000 (sodium hyaluronate 1.0%) in cataract surgery. Methods: Cataract surgery was performed on 60 eyes in 49 patients who were diagnosed with moderate cataracts. 30 eyes were performed with DisCoVisc and a control group with 30 eyes using Hyal 2000 (sodium hyaluronate 1.0%). Phacodynamics was evaluated including ultrasound (US) time, mean US intensity, cumulative dissipated energy (CDE), and amount of used balanced salt solution. Corneal endothelium and corneal thickness were measured preoperatively and 1 day and 1 month and 2 months postoperatively. Results: There were no statistically significant differences in phacodynamic parameters in the two groups. The central corneal thickness change from preoperatively to postoperatively in the DisCoVisc group was +0.07 ± 2.44 μm and Hyal 2000 group +0.84 ± 2.93 μm (p = 0.032) at 2 months. Corneal endothelial cell loss (ECL)(%) at 2 months was 7.67 ± 8.01% in DisCoVisc group and 13.23 ± 15.5% in the Hyal 2000 group (p = 0.005). Conclusions: There was signicant difference between DisCoVisc and Hyal 2000 in the changes of CCT, ECD (Endothelial cell density). (DisCoVisc is effective and provides advantages both cohesive OVDs and dispersive OVDs).
