Method For Inhibiting Attachment Of Microorganisms To Biomedical Devices

摘要

A method for inhibiting adhesion of bacteria to a surface of a biomedical device is disclosed. The method involves at least (a) incorporating one or more non-functionalized polymers having one or more hydrophilic moieties into an ophthalmic device that is a polymerization product of a comonomer mixture comprising: (i) a major amount of a non-silicone-containing hydrophilic monomer; and (ii) an end-terminal functionalized surfactant; and (b) inserting the ophthalmic device in the eye of a patient, wherein the at least one non-functionalized polymer migrates to the surface of the device in a sustained release manner to inhibit adhesion of bacteria to a surface of the biomedical device. Biomedical devices are also disclosed.
