Comparison of 2% hydroxypropyl methylcellulose and 1% sodium hyaluronate in implant surgery

We conducted a prospective randomized clinical trial of 2% hydroxypropyl methylcellulose and 1% sodium hyaluronate (Healon) in routine extracapsular cataract surgery with implantation of a posterior chamber intraocular lens. Of the 84 patients 40 received methylcellulose and 44 received sodium hyaluronate. There was no statistically significant difference in endothelial-cell loss or induced cellular polymegathism between the two groups. The intraocular pressure before and after surgery was similar in the two groups, as was the visual acuity 8 weeks after surgery. The results suggest that 2% hydroxypropyl methylcellulose is a safe and effective alternative to 1% sodium hyaluronate in routine implant surgery.
