CA 2491055

Surface modified medical devices such as intraocular lens implants formed from one or more functional group-containing materials using reactive, hydrophilic polymers for the purpose of reducing or eliminating lens epithelial cell growth thereon, reducing or eliminating silicone oil absorption upon subsequent surgical exposure and/or reducing or eliminating implantation inserter friction is provided herein. Additionally, a method of making and using surface modified intraocular lens implants is provided.

L'invention a trait à des dispositifs médicaux à surface modifiée, tels que des implants intraoculaires constitués d'un ou plusieurs matériaux contenant des groupes fonctionnels et faisant appel à des polymères réactifs et hydrophiles. Lesdits polymères permettent de réduire ou d'éliminer la croissance de cellules épithéliales sur la lentille, de réduire ou d'éliminer l'absorption d'huile de silicone lors d'une intervention chirurgicale ultérieure, et/ou de réduire ou d'éliminer le frottement provoqué par l'instrument d'introduction lors de l'implantation. L'invention concerne également un procédé de production et d'utilisation d'implants intraoculaires à surface modifiée.
