SIST EN ISO 10343:2014 PDF

ISO 10343:2009, together with ISO 15004-1, specifies requirements and test methods for continuously or digitally indicating ophthalmometers. Certain types of ophthalmometer are capable of measuring radii of curvature of contact lenses as described in ISO 18369-3:2006, 4.1. It is assumed that the local corneal front surface and both contact lens surfaces are spherical or toroidal. ISO 10343:2009 takes priority over ISO 15004-1, if differences exist.
