Alcon announced its support for the new standards advising that lens care products be evaluated in accordance with real-world conditions for disinfection, known an ISO standard 18259.
The previous standards for lens care products evaluated the intrinsic antimicrobial efficacy of a solution without a contact lens and without assessing how the product will fare in a contact lens case, according to a press release.
Recently, the U.S. Food and Drug Administration, the International Organization for Standardization and several ophthalmology and optometry associations have been studying the efficacy of testing contact lens solutions in real-world conditions.
In September, the FDA co-sponsored a workshop with the American Academy of Ophthalmology, the American Academy of Optometry, the American Optometric Association and the Contact Lens Association of Ophthalmologists.
According to the press release from Alcon, the discussion included a focus on Acanthamoeba disinfection efficacy, as well as methods for real-world simulated testing of contact lens care products.
ISO published standard 18259 in October; it simulates real-world conditions more closely than the prior disinfection efficacy standard, Alcon said. The new standard adds organic soil and evaluates contact lenses stored in lens cases for various storage times.
