摘要:
A method of retaining hyaluronic acid on a surface of a contact lens. The method comprises providing a contact lens care solution comprising; 0.005 wt. % to 0.05 wt. % of hyaluronic acid in a borate containing buffer, and 0.01 wt. % to 1.0 wt. % of an amphoteric surfactant of general formula I wherein R′ is a C8-C16alkyl optionally substituted with hydroxyl; R2 and R3 are each independently selected from methyl, ethyl, propyl or iso-propyl; and R4 is a C2-C8alkylene optionally substituted with hydroxyl; and soaking the contact lens in the contact lens care solution for at least two hours prior to placement of the contact lens in an eye.
摘要:
Sterilized aqueous solution comprising 0.04% to 0.8% by weight hyaluronic acid with a weight average molecular weight from 0.6 MDa to 3.6 MDa, and one or more buffer components selected from the group consisting of boric acid, sodium borate and sodium dihydrogen phosphate. The aqueous solution also has an ionic strength equivalent to an aqueous concentration of sodium chloride from 4% to 18% by weight of sodium chloride and a pH from 6.4 to 7.2. The solution is also filtered through a filter medium that has an average pore size of 0.25 μm or less to provide a sterilized high salt, hyaluronic acid solution.

摘要:
A process for sterilizing a solution comprising hyaluronic acid. The process comprises providing an aqueous solution of hyaluronic acid with a weight average molecular weight from 0.6 MDa to 3.6 MDa, and the concentration of the hyaluronic acid is from 0.04% to 0.8% by weight. The aqueous solution also has an ionic strength equivalent to an aqueous concentration of sodium chloride from 3% to 30% by weight. Once the aqueous, high salt, hyaluronic acid solution is prepared the solution is maintained at a temperature from 40° C. to 80° C. for at least 1 hour and not longer than six days. Following the heat treatment step, the aqueous solution is filtered through a sterilization filter medium to provide a sterilized high salt, hyaluronic acid solution.
摘要:
An ophthalmic composition comprising one or more antimicrobial components and a dipeptide. The dipeptide comprises a glycine moiety and another amino acid moiety other than glycine. The ophthalmic compositions include contact lens care solutions for cleaning and disinfecting contact lenses.
摘要:
An ophthalmic composition comprising 0.5 ppm to 3 ppm of poly(hexamethylene biguanide), and 0.002 wt. % to 0.03 wt. % of hyaluronic acid. The weight ratio of hyaluronic acid to poly(hexamethylene biguanide) in the composition is from 45:1 to 120:1. The invention is also directed to a method of cleaning, disinfecting or packaging contact lenses with the composition, or to a method of rewetting contact lenses with the composition.
