Method of making silicone containing contact lens with reduced amount of diluents |
| 摘要 |
The present invention relates to a method of manufacturing a contact lens including the steps of: (i) adding reactive components to a mold, wherein the reactive components comprise (a) at least one hydroxy-containing silicone component having a weight average molecular weight from about 200 to about 15,000 g/mole and (b) at least one mono-ether terminated, mono-methacrylate terminated polyethylene glycol having a weight average molecular weight from about 200 to about 10,000 g/mole; (ii) curing the reactive components within the mold to form the contact lens; and (iii) removing the contact lens from said mold. |

1. A method of manufacturing a contact lens, said method comprising the steps of:
(i) adding reactive components to form a reactive mixture, wherein said reactive components comprise (a) at least one hydroxy-containing silicone component having a weight average molecular weight from about 200 to about 15,000 g/mole and (b) at least one monofunctional polyethylene glycol having a weight average molecular weight from about 200 to about 10,000 g/mole; and less than about 15 wt % diluents; (ii) curing said reactive components within said mold to form said contact lens comprising a polymer having a Tg (heating) of less than about 125° C.; and (iii) dry removing said contact lens from said mold. |
