| titleOfInvention | Manufacturing method for contact lens using polymerization method at room temperature |
| abstract | The present invention relates to a method for producing a hydrogel contact lens by a room temperature polymerization method, and more particularly, to a method for preparing a hydrogel contact lens by a method comprising the steps of: mixing 2-hydroxyethyl methacrylate (HEMA), a surfactant, Nitrogen bubbling and homogenizing the solution using a homogenizer to prepare a monomer mixture; Adding a catalyst of an initiator to the monomer mixture, injecting the catalyst into a cast mold, and leaving at a room temperature to produce a contact lens; Removing the unreacted material with ultrapure water, and hydrating the contact lens, removing the contact lens from the cast mold, and manufacturing a hydrogel contact lens, Therefore, it is an object of the present invention to provide a process for efficiently producing a hydrogel contact lens required for mass production, in which polymerization can be carried out without ultraviolet ray or heat treatment required for polymerization of a contact lens in a conventional production method, And thus the production cost can be lowered and a remarkable effect such as improvement of the wettability, oxygen permeability and transmittance of the hydrogel contact lens and reduction of protein adsorption can be attained by using the emulsion polymerization method in which a surfactant is added have. |
