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.

D065347	Hypromellose Derivatives	Polymeric compounds that contain repeating units of hydroxypropyl methylcellulose. The properties of hypromellose polymers can vary greatly and are defined by their molecular weight, the percentage of hydroxyl groups, the percentage of hydroxypropyl groups, and viscosity measurements. They are found a broad variety of commercial products such as FOOD ADDITIVES; EXCIPIENTS; and LUBRICANTS.
