*Therefore this version remains current
ISO 11979-9:2006 is applicable to any intraocular lens whose optic provides two or more rotationally symmetric powers and whose primary indication is the correction of aphakia with the added benefit of useful vision at more than one distance (e.g. far and near).
The term "near vision" as used in ISO 11979-9:2006 includes useful vision at a distance of claimed benefit; e.g. near and/or intermediate distances.
