PURPOSE: To evaluate the effect of different viscoelastic substances on the grade and time course of postoperative @entity3279 . SETTING: Department of Clinical Sciences/Ophthalmology, Ume   University Hospital, Ume  , Sweden. METHODS: This study comprised 62 @entity1 with otherwise healthy eyes who had routine phacoemulsification and @entity2790 ( @entity2790 ) implantation. @entity1 were divided into 3 groups. Group 1 was given Healon GV ( @entity4023 1.4%) at phacoemulsification and @entity2790 implantation. Group 2 was given Viscoat ( @entity4023 3.0%-chondroitin @entity597 4.0%) at phacoemulsification and Healon GV at @entity2790 implantation. Group 3 was given Viscoat at phacoemulsification and Provisc ( @entity4023 1.0%) at lens implantation. The central corneal thickness was measured with ultrasonic pachymetry before surgery and 5 and 24 hours, 1 week, and 1 month after surgery. RESULTS: The mean increase in corneal thickness was significantly greater in Group 1 than in the other 2 groups 5 and 24 hours and 1 week after surgery. CONCLUSIONS: The transient postoperative increase in central corneal thickness was greater in @entity1 receiving Healon GV during phacoemulsification than in @entity1 receiving Viscoat. The use of Provisc or Healon GV for @entity2790 implantation did not affect the postoperative corneal thickness when Viscoat was used for phacoemulsification. The time course of the @entity4 may be explained by a difference between the 2 agents in endothelial protection from ultrasonic, mechanical, or irrigation @entity130 .
