Viscoat versus Healon5 as a corneal protective viscoelastic material in uncomplicated phacoemulsification surgery.

Abstract

Abstract: : Purpose: Comparative study of Viscoat versus Healon5 as a corneal protective viscoelastic agent in cataract surgery using phacomulsification technique Methods: Preoperative corneal thickness was measured in 24 patients using ultrasonic corneal pachymeter and in postoperative day 1 including 9 patients using Viscoat and 15 patients using Healon5, postoperative intraocular pressure was evaluated in both groups. Results: The mean increase in corneal pachymetry on postoperative day 1 was 51.8 micron for Viscoat and 29.3 micron for Healon5 (P=0.067), no statistically significant change was found in intraocular pressure in the 2 groups Conclusions: a trend was observed suggesting that patients undergoing phacomulsification with Viscoat sustained greater increase in corneal pachymetry relative to those with Healon5
