Ophthalmic instruments. Ophthalmometers1 Scope This International Standard, together with ISO 150041, specifies requirements and test methods for continuously or digitally indicating ophthalmometers. Certain types of ophthalmometer have sufficient resolution and range (see Table 2) to adequately measure the radii of curvature of contact lenses complying with ISO 183693: 2006, 4. 1. 3, and Clause 5. It is assumed that the local corneal front surface and both contact lens surfaces are
