#### C.8.25.9 Autorefraction Measurements Module

Table C.8.25.9-1 defines the Attributes used to represent the refractive measurements by an autorefractor of a patient's eyes. Usually both eyes are measured, but sometimes just one.

Table C.8.25.9-1. Autorefraction Measurements Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Autorefraction Right Eye Sequence | (0046,0050) | 1C | A Sequence that specifies refractive measurements of a patient's right eye. Only a single Item shall be included in this Sequence. Required if the right eye is measured. ### Note If Autorefraction Right Eye Sequence (0046,0050) is present, Measurement Laterality (0024,0113), if present, will have a value of R or B as appropriate.
>Sphere Power | (0046,0146) | 1 | Refractive power of the eye that is the same in all meridians, measured at distance (optical infinity), in diopters.
>Include Table C.8.25.6.1-1 “Cylinder Sequence Macro Attributes” |
>Pupil Size | (0046,0044) | 3 | The horizontal diameter measurement of the pupil, in mm.
>Corneal Size | (0046,0046) | 3 | The horizontal diameter measurement of the cornea, in mm.
Autorefraction Left Eye Sequence | (0046,0052) | 1C | A Sequence that specifies refractive measurements of a patient's left eye. Only a single Item shall be included in this Sequence. Required if the left eye is measured. ### Note If Autorefraction Left Eye Sequence (0046,0052) is present, Measurement Laterality (0024,0113), if present, will have a value of L or B as appropriate.
>Sphere Power | (0046,0146) | 1 | Refractive power of the eye that is the same in all meridians, measured at distance (optical infinity), in diopters.
>Include Table C.8.25.6.1-1 “Cylinder Sequence Macro Attributes” |
>Pupil Size | (0046,0044) | 3 | The horizontal diameter measurement of the pupil, in mm.
>Corneal Size | (0046,0046) | 3 | The horizontal diameter measurement of the cornea, in mm.
Distance Pupillary Distance | (0046,0060) | 3 | Distance in mm between the pupils when the patient's object of regard is in the distance, as measured by an autorefractor.
Near Pupillary Distance | (0046,0062) | 3 | Distance in mm between the pupils when the patient's object of regard is at near, as measured by an autorefractor.
