Abstract
The invention is to provide an ophthalmic lens and a manufacturing method thereof. The ophthalmic lens comprises a lens body and an antimicrobial hydrophilic layer thereon, wherein the antimicrobial hydrophilic layer comprises tannic acid and a zwittericionic polymer. The zwittericionic polymer can be selected from one of the group consisting of a phosphorylcholine polymer, a sulfobetaine polymer, a carboxybetaine polymer and a mixed-charge polymer or combinations thereof.
Claims14
An ophthalmic lens comprising:
- a lens body;
- and
- an antimicrobial hydrophilic layer formed on the surface of the lens body, comprising tannic acid and a zwitterionic polymer, wherein the zwitterionic polymer is selected from one of the group consisting of a phosphorylcholine polymer, a sulfobetaine polymer, a carboxybetaine polymer and a mixed-charge polymer, or combinations thereof.
A method for manufacturing an ophthalmic lens comprising:
- (a) providing a lens body;
- (b) immersing the lens body in a tannic acid solution, wherein the tannic acid solution comprising polydopamine;
- and
- (c) immersing the tannic acid treated lens body in a zwitterionic polymer solution, the zwitterionic polymer can be selected from one of the group consisting of a phosphorylcholine polymer, a sulfobetaine polymer, a carboxybetaine polymer and a mixed-charge polymer, or combinations thereof.
