Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee
SC 7, Ophthalmic optics and instruments.
This third edition cancels and replaces the second edition (ISO 16671:2015), which has been technically
revised.
The main changes are as follows:
— Inclusion of applicable sections from ISO 14630 throughout the document and removal of any
reference to that standard. It was further clarified that ophthalmic irrigation solutions (OIS) are
not implants by their intended use but are likely to share some of the risks related to non-active
implants. Therefore, the following clauses and subclauses have been revised: Clause 4 Intended
performance, Clause 5 Design attributes, Clause 7 Sterilization and Clause 9.1 Protection from
damage during storage and transport;
— Clarifications in Clause 3 Terms and definitions (3.1, 3.2, 3.3, 3.4);
— Revised Clause 5.1 General for a more accurate description of design attributes;
— Revised Clause 7 Sterilization to clarify the risks associated with components of OIS sterilized by
ethylene oxide (EO);
— Revised Clause 8 Product stability to clarify that the real time shelf-life testing shall be performed
and the accelerated shelf-life testing is optional;
— Revised Annex E Intraocular irrigation test to provide additional clarification regarding the number
of test and control eyes enrolled in the study and that use of medication during the study that could
possibly impact the study resu
