Adhesiveness of AcrySof to a collagen film

Abstract
F five AcrySof IOLs was attached to a collagen film, slightly pressed in intraocular irrigating solution, and then pulled up and off the film with a DuNouy’s surface balance. The force recorded by the surface balance at the moment it detached from the film was defined as the lens’ adhesiveness. A control experiment was performed using five conventional poly(methyl methacrylate) (PMMA) IOLs. Results: Mean adhesiveness was 2.76 gram-weight (gw) ± 0.55 (SD) for AcrySof and 0.81 ± 0.20 gw for PMMA. The difference was statistically significant (P < .0001, t-test). Conclusion: AcrySof may have a strong tendency to adhere to the lens capsule, contributing to posterior and anterior capsule clarity and preventing lens decentration in vivo. aReprint requests to Toyofumi Nagata, MD, Department of Ophthalmology, Hamamatsu University School of Medicine, 3600 Handa, Hamamatsu, Shizuoka, 431-31, Japan.
