C.8.25.11 Subjective Refractive Measurements Module

Table C.8.25.11-1 defines the Attributes used to represent the subjective refractive measurements of a patient’s eyes. Usually both eyes are measured, but sometimes just one.

Table C.8.25.11-1SUBJECTIVE REFRACTIVE MEASUREMENTS MODULE ATTRIBUTES

Attribute Name Tag Type Attribute Description
Subjective Refraction Right Eye Sequence (0046,0097) 1C A sequence that specifies the subjective 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.
>Include ‘Subjective Refractive Measurements Macro' Table C.X.8.11-2
Subjective Refraction Left Eye Sequence (0046,0098) 1C A sequence that specifies the subjective 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.
>Include ‘Subjective Refractive Measurements Macro' Table C.X.8.11-2
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 a phoropter.
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 a phoropter.
Intermediate Pupillary Distance (0046,0063) 3 Distance in mm between the pupils when the patient’s object of regard is at an intermediate distance, as measured by a phoropter.
Other Pupillary Distance (0046,0064) 3 Distance in mm between the pupils when the patient’s object of regard is at the distance specified in the attribute Add Other Sequence (0046,0102), as measured by a phoropter.

Table C.8.25.11-2 describes the attributes used for the Subjective Refractive Measurements Macro

Table C.8.25.11-2SUBJECTIVE REFRACTIVE MEASUREMENTS MACRO

Attribute Name Tag Type Attribute Description
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 'Cylinder Sequence Macro' Table C.8.25.6.1-1
Include ‘Prism Sequence Macro’ Table C.8.25.6.2-1
Add Near Sequence (0046,0100) 1C A sequence that specifies refractive measurements of the eye to correct for inability to focus at near while wearing the distance prescription. Only a single item shall be included in this sequence. Required if near point refraction is done.
>Add Power (0046,0104) 1 Additional power relative to the distance correction, expressed in diopters, that allows best corrected visual acuity at the defined viewing distance.
>Viewing Distance (0046,0106) 3 The distance, in cm, for testing visual acuity corresponding to the value of Add Power (0046,0104) in this sequence.
Add Intermediate Sequence (0046,0101) 1C A sequence that specifies refractive measurements of the eye to correct for inability to focus at intermediate distance while wearing the distance prescription. Only a single item shall be included in this sequence. Required if intermediate point refraction is done.
>Add Power (0046,0104) 1 Additional power relative to the distance correction, expressed in diopters, that allows best corrected visual acuity at the defined viewing distance.
>Viewing Distance (0046,0106) 3 The distance, in cm, for testing visual acuity using the value of Add Power (0046,0104) in this sequence item.
Add Other Sequence (0046,0102) 1C A sequence that specifies refractive measurements of the eye to correct for inability to focus at the below specified distance while wearing the distance prescription. Only a single item shall be included in this sequence. Required if refraction is done at less than distance (optical infinity), but at a distance other than “near” or “intermediate”.
>Add Power (0046,0104) 1 Additional power relative to the distance correction, expressed in diopters, that allows best corrected visual acuity at the defined viewing distance.
>Viewing Distance (0046,0106) 3 The distance, in cm, for testing visual acuity corresponding to the value of Add Power (0046,0104) in this sequence item.
