22、ber 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, governmen
23、tal and nongovernmental, 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
24、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

31、aocular lenses are used to correct refractive errors in patients with a noncataractous crystalline lens. They are typically used for patients with higher amounts of myopia or hyperopia. Originally, they contained a spherical monofocal optic to correct spherical errors but later variations utilized a
32、 toric optic to also correct refractive astigmatism. Phakic intraocular lenses with a multifocal optic can be used to correct presbyopia in patients that have lost the ability to accommodate.The requirements and recommendations in the ISO series of standards for aphakic intraocular lenses for the mo
33、st part also apply to phakic intraocular lenses. Those standards should be reviewed for guidance that would also be applicable to phakic intraocular lenses (e.g. shelflife testing, biocompatibility testing, etc.).This document provides requirements and recommendations for phakic intraocular lens inv
34、estigations of new models. Risk analysis should be used to determine the investigational design, if needed, for models that are modifications of parent phakic models. For modifications of a parent phakic model refer to ISO/TR 22979. ISO 2018 All rights reserved vBS EN ISO 1197910:2018This page delib

36、ation to modify its refractive power.There are three main categories of phakic intraocular lenses depending on the optical design:a) Phakic monofocal (PIOL);b) Phakic multifocal (PMIOL); andc) Phakic toric (PTIOL).Each of these categories is further designated for implantation in either the anterior
37、 or posterior chamber of the anterior segment of the eye.The basic phakic IOL requirements apply to all the types. Additional requirements apply to PMIOL and PTIOL designs.This document addresses specific clinical requirements for phakic IOLs that are not addressed in the other parts of ISO 11979.2
