ISO 10343:2014 specifies requirements and test methods for continuously or digitally indicating ophthalmometers. Certain types of ophthalmometer have sufficient resolution and range to adequately measure the radii of curvature of contact lenses. It is assumed that the local corneal front surface and both contact lens surfaces are spherical or toroidal.
Abstract
Overview
ISO 10343:2014 specifies requirements and test methods for continuously or digitally indicating ophthalmometers used to measure the radii of curvature and principal meridians of the corneal front surface and contact lenses. The standard assumes local corneal and contact-lens surfaces are spherical or toroidal and takes precedence over where differences exist. It covers instrument performance, optical checks, test devices, documentation, and marking for compliance.
