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 Table C.8.25.11-2 “Subjective Refraction Measurements Macro Attributes”

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 Table C.8.25.11-2 “Subjective Refraction Measurements Macro Attributes”

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.

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”

Include Table C.8.25.6.2-1 “Prism Sequence Macro Attributes”

Vertex Distance

(0022,000F)

3

The distance from the corneal vertex of the eye to the back of the corrective lens, in mm.

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.
