ISO International Standard

ISO 19979:2018 provides guidance to manufacturers for the development of information to be provided to eye care practitioners for the hygienic management of trial hydrogel, composite and rigid gas-permeable (RGP) contact lenses intended for multipatient use.

ISO 19979:2018 does not apply to:

– labelling of contact lenses;

– the inactivation of prions and viruses since there are no standardised methods available for contact lenses.

ISO 19979:2018 can be used as guidance for the development of a hygienic management procedure for multipatient use.

NOTE ISO 14729 does not cover multipatient use.
