Process for making contact lenses |
| abstract |
A process for making an article, and the articles formed thereby from an ionically cross-linked polymer; said process comprising the essential steps of forming a composition comprising a said polymer and a nonvolatile organic plasticizer therefor, forming said article by molding and/or machining steps, leaching said plasticizer from the formed article, and replacing it with water or an aqueous solution. The process is particularly useful in the manufacture of a novel contact lens because it results in articles of unexpectedly good color characteristics and a high water content which had never before been achieved. |
