Overview
ISO 24157:2008/Amd 1:2020 is an important amendment to the international standard focused on ophthalmic optics and instruments, specifically addressing the reporting of aberrations of the human eye. This amendment updates the methods used to present and characterize ocular aberrations, contributing to the consistent and accurate assessment of visual optics across clinical and research settings. Developed by ISO Technical Committee ISO/TC 172/SC 7 on ophthalmic optics and instruments, the amendment reflects advancements in terminology and measurement techniques for eye aberrations.
Key Topics
The amendment introduces essential updates and clarifications related to the representation of aberrations in the human eye, including:
- Definition Improvements: Refinement of key terms such as the "line of sight," describing the path of light rays from the fixation point through the eye’s pupil to the foveola. This clarifies the optical axis relevant to measurement and correction of aberrations.
- Sampling Points: Addition of parameters regarding the number of sampling points used in aberration measurements, which impacts the precision and resolution of eye wavefront analysis.
- Mathematical Expressions: Revision of polynomial expansions and Zernike coefficients used to describe complex aberration patterns, enhancing standardized calculations for clinical diagnostics and lens design.
- Consistency with Related Standards: Aligning terminologies and measurement approaches with related ISO references, such as ISO 13666:2019, for coherent use in ophthalmic instrumentation.
Applications
ISO 24157:2008/Amd 1:2020 is widely applied in the following areas:
- Clinical Ophthalmology: Facilitates accurate diagnosis of visual defects by standardizing aberration reporting, improving the tailoring of corrective lenses and surgical procedures.
- Optical Instrument Development: Guides manufacturers in designing wavefront sensors, autorefractors, and other devices that measure and analyze ocular aberrations.
- Vision Research: Provides a reliable framework for comparing optical aberration data across studies, aiding in the development of new vision correction technologies such as customized contact lenses and intraocular lenses.
- Quality Assurance: Supports regulatory compliance and quality control in ophthalmic optics production by defining uniform reporting methods.
Related Standards
Professionals utilizing ISO 24157:2008/Amd 1:2020 should also consider relevant standards in ophthalmic optics and metrology that complement this amendment, including:
- ISO 13666:2019 - Eye and ophthalmic optics terminology, harmonizing terms like “line of sight” for consistency.
- ISO 8980 Series - Specifies requirements for ophthalmic lenses, which may incorporate aberration data in quality assessments.
- IEC 60601-2-41 - Medical electrical equipment standards for ophthalmic instruments, ensuring device safety and performance.
- ISO 8970 - General methods for optical instrument calibration pertinent to aberration measuring devices.
By adopting ISO 24157:2008/Amd 1:2020, eye care professionals, instrument manufacturers, and researchers enhance interoperability, measurement accuracy, and communication in the field of ophthalmic optics. This leads to better visual health outcomes through precise aberration analysis and customized optical solutions.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member 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, governmental and non-governmental, 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 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).
