DESCRIPTION
BS EN ISO 11986:2017
This standard BS EN ISO 11986:2017 Ophthalmic optics. Contact lenses and contact lens care products. Determination of preservative uptake and release is classified in these ICS categories:
- 11.040.70 Ophthalmic equipment
This document provides general procedures for the selection of methods, preparation of samples, and the conduct of testing for the uptake and release of preservatives from contact lenses.
NOTE 1 Due to the manifest difficulties of reproducibility when coating contact lenses with mineral and organic deposits encountered during lens wear, these methods are only applicable to new and unused contact lenses.
NOTE 2 Preservative depletion by a contact lens in the limited volume of a lens case could compromise disinfection performance. This document does not measure disinfection performance.
