Abstract
The present invention is concerned with a biomedical molding comprising a non-biodegradable biocompatible organic polymer comprising attached to its surface radicals of formula wherein the variables are as defined in the claims. The biomedical moldings of the invention are radiation sensitive and may be used, for example, as intraocular lens in ophthalmic surgery.
Claims12
A biomedical molding comprising a non-biodegradable biocompatible organic polymer comprising attached to its surface radicals of formula
- wherein R1 is hydroxy, C1-C4-alkyl, C1-C4-alkoxy, sulfo, nitro, trifluoromethyl or halogen, m is an integer from 0 to 2, and Z is a group which functions as a triggerable precursor for carbene, nitrene or benzhydrol formation.
A method of using a non-biodegradable biocompatible organic polymer comprising attached to its surface radicals of formula
- wherein
- R1 is an electron-withdrawing substituent, m is an integer from 0 to 2, and
- Z is a group which functions as a triggerable precursor for carbene, nitrene or benzhydrol formation, as an intraocular lens for the implantation into or onto a cornea, comprising the step of attaching said organic polymer to the cornea.
