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.

|---|---|---|---|

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. NoteIf 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. NoteIf Autorefraction Left Eye Sequence (0046,0052) is present, Measurement Laterality (0024,0113), if present, will have a value of L or B as appropriate. |

>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. |
