Ophthalmic instruments - Ophthalmometers (ISO 10343:2009)
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.
Ophthalmische Instrumente - Ophthalmometer (ISO 10343:2009)
Diese Internationale Norm legt zusammen mit ISO 15004-1 Anforderungen und Prüfverfahren für kontinuierlich
oder digital anzeigende Ophthalmometer fest. Einige Typen von Ophthalmometern (in Tabelle 1 als
Klasse 1 bezeichnet) sind geeignet, Krümmungsradien von Kontaktlinsen nach ISO 18369-3:2006, 4.1 zu
messen. Es wird vorausgesetzt, dass die lokale Vorderfläche der Hornhaut und beide Oberflächen der
Kontaktlinse sphärisch oder torisch sind.
Diese Internationale Norm hat Vorrang vor ISO 15004-1, wenn Unterschiede vorliegen.
Instruments ophtalmiques - Ophtalmomètres (ISO 10343:2009)
L'ISO 10343:2009, conjointement à l'ISO 15004-1, spécifie les exigences et les méthodes d'essai relatives aux ophtalmomètres à indication continue ou numérique. Certains types d'ophtalmomètres permettent de mesurer les rayons de courbure des lentilles de contact conformément à l'ISO 18369-3:2006, 4.1. Il est admis que la surface locale avant de la cornée, ainsi que les surfaces des lentilles de contact sont sphériques ou toroïdales.
L'ISO 10343:2009 prévaut sur l'ISO 15004-1, dans le cas où une différence existe.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10343 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 7,
Ophthalmic optics and instruments.
This second edition cancels and replaces the first edition (ISO 10343:1997), which has undergone minor
revision to update normative references.
INTERNATIONAL STANDARD ISO 10343:2009(E)
Ophthalmic instruments — Ophthalmometers
1 Scope
This International Standard, together with ISO 15004-1, specifies requirements and test methods for
continuously or digitally indicating ophthalmometers. Certain types of ophthalmometer (designated as code 1
in Table 1) 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.
This International Standard takes priority over ISO 15004-1, if differences exist.
