Comparative evaluation of efficacy and safety of ophthalmic viscosurgical devices in phacoemulsification

Comparative evaluation of efficacy and safety of ophthalmic viscosurgical devices in phacoemulsification.

Article Specifications

The randomize clinical trial was published in 2005 in journal of BMC ophthalmology (IF 2005:1.44) by Indian ophthalmologists. In this article the efficacy and safety of 3 types of OVDs have been evaluated. 56 patient over 40 with preoperative diagnosed glaucoma and/or IOP greater than 20 mmHg preoperatively were excluded from the study. Patients depending on type of OVD they used divided in 3 groups: (1) 19 patients. Viscoat® (Sodium chondroitin sulfate 4.0% & sodium hyaluronate 3.0%) was used; (2) 19 patients, Healon GV® (Sodium hyaluronate 1.4%) was used; (3) 18 patients, Healon 5® (Sodium hyaluronate 2.3%) was used. And then Parameters like uncorrected and best corrected visual acuity, specular microscopy, intraocular pressure and pachymetry both preoperatively and postoperatively on day 1, 1 week, 1 month and 3 months and development of any complication both intraoperative and postoperative were evaluated.

Results

This study showed that the safety and efficacy of the three viscosurgical devices Viscoat®, Healon GV® and Healon 5® in performing phacoemulsification is comparable. However, Viscoat® can result in a mild transient rise in the intraocular pressure.
