Document Type and Number:
Japanese Patent JP4781840
Kind Code:
B2
Abstract:
Disclosed are methods and apparatus for hydrating ophthalmic lenses and leaching excess materials from the ophthalmic lenses. The methods include the steps of exposing contact lenses with a hydration solution comprising about 30 to 70 percent isopropyl alcohol and water. In some embodiments, the hydration solution is maintained at an elevated temperature. Exposure to a first hydration solution causes the ophthalmic lenses to swell to a size larger than their functional size, and exposure to a second ophthalmic solution causes the lenses to shrink back to a functional size.
