摘要:
A method of reducing foam formation and improving odor in ophthalmic solutions, such as multipurpose cleaning and conditioning solutions and contact lens packing solutions. The ophthalmic solutions contain surfactant and aroma compound in an amount effective to decrease foam formation. The aroma compound has a low molecular weight and pleasing smell.

Ophthalmic composition that includes 0.05% w/v to 2% w/v diglycine or a salt thereof; 0.01 ppm to 3 ppm poly(hexamethylene biguanide); 1 ppm to 10 ppm α-[4-tris(2-hydroxyethyl)ammonium chloride-2-butenyl]poly[1-dimethylammonium chloride-2-butenyl]-ω-tris(2-hydroxyethyl)ammonium chloride; and 0.1% w/v to 2% w/v of one or more boron buffering compounds.
摘要:
Ophthalmic compositions that comprise 0.1 ppm to 10 ppm of a cationic antimicrobial component selected from the group consisting of biguanides, polymeric biguanides, quaternium ammonium compounds and any one mixture thereof; 0.005 wt. % to 0.15 wt. % of hyaluronic acid; and 0.01 wt. % to 1.0 wt. % of an amphoteric surfactant of general formula I wherein R1 is R or —(CH2)n—NHC(O)R, wherein R is a C8-C16alkyl optionally substituted with hydroxyl and n is 2, 3 or 4; R2 and R3 are each independently selected from methyl, ethyl, propyl or iso-propyl; and R4 is a C2-C8alkylene optionally substituted with hydroxyl. The invention is also direct to the use of the ophthalmic compositions to clean and disinfect contact lenses, and in particular, soft, silicone hydrogel contact lenses.

摘要:
Compositions comprise a polymer having units of an amino sugar, a polyol other than sorbitol, and boric acid, a salt thereof, or a combination thereof. Such compositions remain for an extended period in the eye and can be used for relief, treatment, or control of a condition of dry eye or discomfort resulting therefrom.
摘要:
Ophthalmic compositions that comprise 0.1 ppm to 50 ppm of a cationic antimicrobial component selected from the group consisting of biguanides, polymeric biguanides, quaternium ammonium compounds and any one mixture thereof; 0.005 wt. % to 2 wt. % of an anionic biopolymer; and 0.01 wt. % to 2 wt. % of an amphoteric surfactant of general formula I wherein R1 is R or —(CH2)n—NHC(O)R, wherein R is a C8-C30alkyl optionally substituted with hydroxyl and n is 2, 3 or 4; R2 and R3 are each independently selected from C1-C4alkyl; R4 is a C2-C8alkylene optionally substituted with hydroxyl; and Y is CO2− or SO3. The invention is also direct to the use of the ophthalmic compositions to clean and disinfect contact lenses, and in particular, soft, silicone hydrogel contact lenses.
