Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 8) (First Revision) which is identical with ISO 11979-8 : 2017 ‘Ophthalmic implants — Intraocular lenses — Part 8: Fundamental requirements ‘ issued by the International Organization for Standardization was adopted by the Bureau of Indian Standards on recommendation of the Ophthalmic Instruments and Appliances Sectional Committee and after approval of the Medical Equipment and Hospital Planning Division Council.

This standard was originally published in 1996 as IS 14323 : 1996 ‘Intraocular lenses — Specification’. It was superseded as IS/ISO 11979-8 : 2006 ‘Ophthalmic implants — Intraocular lenses: Part 1 Fundamental requirements’. The first revision of this standard has been undertaken to align it with the latest version of ISO 11979-8 : 2017.

This Indian Standard is published in various parts. The other parts in this series are:

Part 1 Vocabulary

Part 2 Optical properties and test methods

Part 3 Mechanical properties and test methods

Part 4 Labelling and information

Part 5 Biocompatibility

Part 6 Shelf-Life and transport stability

Part 7 Clinical investigations of intraocular lenses for the correction of aphakia

Part 10 Phakic intraocular lenses

The text of ISO standard may be approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in the Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
