摘要： A surface-modified contact lens, having a surface contact angle hysteresis of less than 15°, includes a lens body and a first surface modification layer disposed on a surface of the lens body. The first surface modification layer comprises a first reactive hydrophilic polymer. The surface of the lens body has a first functional group or a second functional group, and the first reactive hydrophilic polymer has a third functional group or a fourth functional group. A first covalent cross-link bond is formed between the surface of the lens body and the first surface modification layer. The first covalent cross-link bond is formed by reacting the first functional group or the second functional group of the surface of the lens body with the third functional group or the fourth functional group of the first reactive hydrophilic polymer.

摘要： A method for manufacturing a hydrophilic silicone macromer is provided. A hydrosilylation between a Si—H bond of a polysiloxane and a C═C bond of a hydrophilic mononmer is performed by using a rhodium-containing catalyst to form the polysiloxane having a hydrophilic side chain having an amide group or a phosphoryl choline group. After performing an end-capping reaction, the hydrophilic silicone macromer is formed.
