摘要:
A method for coating hydrogel and silicone hydrogel articles, and articles made by the method, are provided in which the coating is first applied to the molding surface in which an article-forming material will be cured to form the article. The method permits the thickness and uniformity of the coating to be more easily controlled than in known coating methods.
摘要:
The present invention relates to stabilized ophthalmic solutions comprising at least one peroxide. In one embodiment, the present invention relates to an ophthalmic solution comprising a pH between about 6 and about 8 and about 50 to about 1000 ppm hydrogen peroxide and about 0.005 wt % (50 ppm) to about 0.05 wt % (500 ppm) at least one salt of diethylenetriamine pentaacetic acid selected from the group consisting of calcium salts of diethylenetriamine pentaacetic acid, zinc salts of diethylenetriamine pentaacetic acid and mixed calcium/zinc salts of diethylenetriamine pentaacetic acid.The present invention further relates to a method for preserving ophthalmic solution comprising at least one peroxide.
摘要:
The present invention relates to ophthalmic compositions comprising a pH between about 6 and about 8 and about 50 to about 1000 ppm hydrogen peroxide, about 100 ppm to about 2000 ppm of at least one chlorite compound and about 20 to 100 ppm of at least one saturated, polymeric quaternium salt. The ophthalmic compositions of the present invention display improved antifungal efficacy against fusarium solani.
摘要:
