NATIONAL FOREWORD

This Indian Standard (Part 9) which is identical with ISO 11979-9 : 2006 ‘Ophthalmic implants - Intraocular lenses - Part 9: Multifocal intraocular lenses’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Ophthalmic Instruments and Appliances Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.

This standard is published in ten parts. The other parts of 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

Part 8 Fundamental requirements

Part 10 Phakic intraocular lenses

The IS/ISO 11979 series will supersede IS 14323 : 1996 ‘Intraocular lenses - Specification’ and after the publication of this series of standards, IS 14323 shall be treated as withdrawn.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in 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.
