Clinicopathologic findings after in-the-bag implantation of open-loop polymethylmethacrylate and silicone lenses in the rabbit eye

J Cataract Refract Surg. 1987 Nov;13(6):630-4. doi: 10.1016/s0886-3350(87)80152-9.


Two lens models, one all silicone with J-loop haptics, the second with PMMA optics and angled polypropylene C-loop haptics, were implanted in the capsular bag of 36 rabbit eyes following extracapsular lens extraction. Technical ease of implantation, inflammatory response, lens position, and fibrin exudation as well as precipitate formation were examined. Biomicroscopy, light and phase-contrast microscopy were used. Differences in haptic vulnerability, lens position, and fibrin clot formation were found between the two lens types. Lens-specific differences in precipitate formation could not be substantiated.
