Abstract
The invention relates generally to a method and composition for the treatment of contact lenses, especially silicone and hydrophilic plastic contact lenses, to remove inorganic deposits and to prevent the formation of inorganic deposits on the lenses. One of the problems connected with these types of lenses is the formation, over a period of time, of insoluble inorganic deposits on the lenses. These deposits are thought to be primarily calcium based, e.g., calcium phosphate and calcium carbonate, but may also contain other inorganic materials and associated organic materials, e.g., protein. The presence of these insoluble inorganic deposits is a common cause of lens intolerance and decreased visual acuity. The method comprises contacting a contact lens with an aqueous solution containing an effective amount of a polymetaphosphate, gluconic acid or salts thereof as sequestering agent for a period of time sufficient to remove existing inorganic deposits and to prevent formation of inorganic deposits. The solution may be a preserved saline solution containing 0.01-20% by weight of the sequestering agent.
