Influence of viscoelastic substances used in cataract surgery on corneal metabolism and endothelial morphology: Comparison of Healon and Viscoat

Influence of viscoelastic substances used in cataract surgery on corneal metabolism and endothelial morphology: Comparison of Healon and Viscoat.

Article specifications

This prospective, randomized, double blind, clinical trial was published in 2001 in Journal of cataract and refractive surgery (IF 2015:2.72) by Austrian ophthalmologists. In this article the influence of cohesive and dispersive ophthalmic viscosurgical devices (OVDs) on endothelial morphology and corneal metabolism during cataract surgery were evaluated. 50 eyes of 43 patients were randomized into 2 groups before surgery. Phacoemulsification with implantation of a posterior chamber intraocular lens was performed in all patients. In half the patients, sodium hyaluronate 1% (Healon) was used as the OVD and in the other half, sodium hyaluronate3%–chondroitin sulfate 4% (Viscoat). Examinations were performed preoperatively and 3 days, 1 and 4 weeks, and months postoperatively.

Results

There was no significant difference between Healon and Viscoat.
