MANUFACTURING METHOD OF A POROUS CONTACT LENS HAVING IMPROVED OXYGEN TRANSMITTANCE AND THE POROUS CONTACT LENS MANUFACTURED BY USING THE SAME

摘要

PURPOSE: A manufacturing method of a porous contact lens is provided to have high oxygen transmittance, by forming a plurality of holes, which has nano level sizes by using the solubility of water soluble salts.;CONSTITUTION: A manufacturing method of a porous contact lens comprises: a step of forming water soluble salt to have nano-size; a step of adding and mixing the nano-size water soluble salt into the raw material for contact lens; a step of molding a contact lens by using the mixed raw material for contact lens; and a step of removing the water soluble salt by cleaning the contact lens by a solution.;COPYRIGHT KIPO 2012
