Structural properties and biocompatibility of polymers used in ophthalmology.
The chemico-physical and structural properties and biocompatibility of new polymers used for intraocular lens manufacture are studied.  In particular, the vibrational infrared and Raman spectra of fluorinated polymethacrylates are presented and discussed in relation to those of polymethylmethacrylate (PMMA), in order to correlate their structure with their properties and biocompatibility.  The thermal analysis points out that the polymers are more stable than polymethylmethacrylate and the biocompatibility tests show that they are as biocompatible as polymethylmethacrylate.
