SILICONE HYDROGELS HAVING A STRUCTURE FORMED VIA CONTROLLED REACTION KINETICS |
摘要 |
The present invention relates to a process comprising the steps of reacting a reactive mixture comprising at least one silicone-containing component, at least one hydrophilic component, and at least one diluent to form an ophthalmic device having an advancing contact angle of less than about 80°; and contacting the ophthalmic device with an aqueous extraction solution at an elevated extraction temperature, wherein said at least one diluent has a boiling point at least about 10° higher than said extraction temperature. |

1. A silicone hydrogel formed from a reaction mixture comprising about 37 to about 75 wt % of at least one slow-reacting hydrophilic monomer having a slow-reacting hydrophilic monomer kinetic half life;
at least one silicone-containing component having a silicone-containing component kinetic half life, which may be optionally substituted with at least one hydroxyl containing group; at least one photoinitiator; and at least one hydroxyl-containing component selected from said silicone-containing components substituted with at least one hydroxyl group, at least one hydroxyalkyl monomer, and mixtures thereof, wherein ratio of said slow-reacting hydrophilic component half life to said silicone-containing component half life is at least 2. |
