Annex AA OPHTHALMIC REFRACTIVE MEASUREMENTS STORAGE SOP CLASSES (Normative)

AA.1 Scope

Refractive instruments are the most commonly used instruments in eye care. At present many of them have the capability for digital output, but their data is most often addressed by manual input into a paper or electronic record. Lensometry, Autorefraction, Keratometry, Subjective Refraction, and Visual Acuity Measurements SOP Classes support devices such as lensometers, auto-refractors, keratometers, autophoropters, and autoprojectors.

AA.2 Behavior of a SCP

For a device that is both a SCU and a SCP of these Storage SOP Classes, in addition to the behavior for the Storage Service Class specified in B.2.2, the following additional requirements are specified for Structured Reporting Storage SOP Classes:

— A SCP of these SOP Class shall support Level 2 Conformance as defined in Section B.4.1.

Note: This requirement means that all Type 1, Type 2, and Type 3 Attributes defined in the Information Object Definition and Private Attributes associated with the SOP Class will be stored and may be accessed.
