A prospective comparison of Amvisc and Healon in cataract surgery.

A prospective, randomly assigned, double-masked study was designed to compare two solutions of sodium hyaluronate--Amvisc and Healon. All cases were planned extracapsular cataract extractions with posterior chamber intraocular lenses performed by a single surgeon in glaucomatous and nonglaucomatous eyes. Subjective performance of the products were rated in regard to ability to maintain the chamber, coat the intraocular lens, dilate the pupil, separate the leaves of the capsule, and be easily removed. Objective comparisons of intraocular pressure, anterior chamber reaction, and endothelial cell loss were also made. There was no subjective or objective difference between the two products.
