PURPOSE: To analyze the surface quality before and after folding of 2 @entity2790 ( @entity2790 ) models designed for microincision @entity231 surgery. SETTING: Eye Clinic and Department of @entity1 Pathology and Oncology, University of Florence, Florence, Italy. METHODS: Two @entity2790 models now available for sub-2.0 mm microincision were studied: UltraChoice 1.0 Rollable ThinLens (ultrathin lens by ThinOptX) and AcriSmart (foldable lens by AcriTec). Eight IOLs of each model were examined. @entity4653 ( @entity4653 ) was performed before and after @entity2790 folding with a dedicated injector. Special attention was given to the optic surface and edges, the optic-haptic junction, and the haptic itself. RESULTS: Initially, the surface quality of IOLs was evaluated before folding. On @entity4653 , smooth and homogeneous optic and haptic surfaces were revealed in both @entity2790 models with no surplus material or molding flashes; edge finish of all optics showed no evidence of ridges. The @entity2790 surfaces were evaluated after insertion into their injectors and after ejection at room temperature. After folding, the microincision IOLs showed no sign of surface alteration, probably because of their high water content, which makes these IOLs soft and flexible. CONCLUSIONS: Visual results and long-term biocompatibility of the IOLs are influenced by surface properties. In recent years, there has been a trend toward microincision @entity231 surgery. Our study shows that the 2 @entity2790 models now available for sub-2.0 mm microincision have acceptable surface properties.
