Edina, Minnesota (January 12, 2006) — Newly published data obtained from a study conducted at Chu Vision Institute suggest that the effects on the central corneal thickness after application of viscous tetracaine HCI .5% (TetraVisc™) are insignificant in comparison to non-preserved carboxymethylcellulose sodium 0.5%.
A Single-center, open label study of 20 healthy eyes of 10 patients was conducted. Baseline measurements of best-corrected distance visual acuity and Orbscan® analysis were performed on both eyes. In each patient, the right eye served as the control and received non-preserved carboxymethylcellulose sodium 0.5% while the left eye received one drop of TetraVisc™. After 5 minutes, best-corrected visual acuity and Orbscan®analysis were repeated on both eyes.
The results of the study showed an average overall central corneal thickness was increased to a greater degree in the eyes instilled with carboxymethylcellulose sodium. The mean central corneal thickness change was increased by 11.1 microns with carboxymethylcellulose sodium and 9.2 microns with TetraVisc™. There were no significant changes in visual acuities before or after instillation of carboxymethylcellulose sodium or TetraVisc™.
Patrick H. Witham, OCuSOFT® Executive Vice President, adds, “Additional studies relating to TetraVisc™ are ongoing but the safety profile data are very good. I believe we will continue to see great things from TetraVisc™ and I am extremely pleased with how the industry has responded to the product.”
