ISO 10343:1997 Ophthalmic instruments -- Ophthalmometers
standard by International Organization for Standardization, 07/01/1997
More info
Full Description
This International Standard, together with ISO 15004, specifies requirements and test methods for continuously or digitally indicating ophthalmometers. Certain types of ophthalmometers (designated as code 1 in table 1) are capable of measuring radii of curvature of contact lenses as described in ISO 103381). It is assumed that the local cornea1 front surface and both contact lens surfaces are spherical or toroidal.
This International Standard takes priority over ISO 15004, if differences exist.
