Alexandria, VA (November 3, 2010) – The American National Standards Institute (ANSI) Z80 Accredited Standards Committee for Ophthalmic Optics is pleased to announce a new standard for toric intraocular lenses (IOL) – ANSI Z80.30. The standard applies to any monofocal IOL whose primary indication is the reduction of astigmatism either in the correction of aphakia or the modification of the refractive power of a phakic eye. It does not include IOLs used to correct presbyopia.
The ANSI Z80.30 standard addresses the vocabulary, optical properties and test methods, mechanical properties and test methods, labeling, biocompatibility, sterility, shelf-life and transport stability, and clinical investigations necessary for IOLs. Specifically, it addresses the requirements and test methods for IOLs used to correct inherent residual astigmatism in the aphakic eye.
“After the crystalline lens of the eye has been removed, toric lens implants can modify the residual refractive state in such an eye in order to reduce pre-operatively or intra-operatively measured astigmatic refractive error that generally arises from the cornea,” said Dr. Carl Tubbs, chair of the ANSI Z80 subcommittee on Medical Ophthalmic Devices. “This standard will help to ensure that patients receive the best IOLs possible.”
The new ANSI Z80.30 standard for toric IOLs can be purchased at the ANSI web store.
