Abstract:
Viscoelastic materials have been used to protect corneal endothelial cells and intraocular tissue. The chemical composition of Healon(R) (sodium hyaluronate) is different from that of Viscoat(R). Thus, to compare the chemical effect between Healon(R) and Viscoat(R), we evaluated the postoperative change of intraocular pressure (lOP) and density of corneal endothelial cells in 60 cataractous patients. The age distribution was from 38 to 66. In group I, Healon(R) was used and removed during the operation. In group II, Viscoat(R) was used and removed during the operation. In group III. Viscoat(R) was used but not removed during the operation. We found the fact that Viscoat(R) has a tendency to increase lOP at early postoperative period if not removed. However, returning of the increased lOP to normal was faster in Group II (Viscoat(R)) than in Croup I (Healon(R). And also Viscoat(R) was found to have better protective effect to the corneal endothelial cells if not removed during the operation.
