  • OPHTHALMIC CONTACT LENS SOLUTIONS CONTAINING FORMS OF VITAMIN B
    Publication number: 20130079422
    Abstract: The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.

  • Method for rendering a contact lens wettable
    Patent number: 7678836
    Abstract: An ophthalmic solution comprising a polyethoxylated glyceride in the range of 0.001 to about 10 percent by weight and a buffer agent. These solutions impart surprising comfort and wearability to contact lenses. At the same time the solutions provide good preservative capacity and do not increase protein deposit.

  • Ophthalmic and contact lens solutions comprising imidazole
    Patent number: 7067547
    Abstract: The present invention relates to contact lens solutions employing imidazole as an additive. Lenses treated with these solutions have improved resistance to protein and other polymeric depositions. The addition of imidazole to the solutions decreases the denaturalization of proteins during the cleaning cycles, and coats treated lenses to decrease the number of active binding sites.
