#### C.8.25.16 Intraocular Lens Calculations Module

Table C.8.25.16-1 defines the Attributes used to calculate the power of an intraocular lens to be placed in a patient's eye. This is typically done for both eyes for comparison, but may be for just one eye. Values used may be measurements acquired using the axial length measurements device, manually entered, or derived from a referenced SOP class or other data source.

Table C.8.25.16-1. Intraocular Lens Calculations Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Intraocular Lens Calculations Right Eye Sequence | (0022,1300) | 1C | Calculations of intraocular lens power for a patient's right eye. One or more Items shall be included in this Sequence. Required if the device calculated intraocular lens power for the right eye. ### Note If Intraocular Lens Calculations Right Eye Sequence (0022,1300) is present, Measurement Laterality (0024,0113), if present, will have a value of R or B as appropriate.
>Include Table C.8.25.16-2 “Intraocular Lens Calculations Macro Attributes” |
Intraocular Lens Calculations Left Eye Sequence | (0022,1310) | 1C | Calculations of intraocular lens power for a patient's left eye. One or more Items shall be included in this Sequence. Required if the device calculated intraocular lens power for the left eye. ### Note If Intraocular Lens Calculations Left Eye Sequence (0022,1310) is present, Measurement Laterality (0024,0113), if present, will have a value of L or B as appropriate.

###### C.8.25.16.1.1 Referenced SOP Sequence

Data in an IOL Calculations SOP Instance will frequently be gathered from other SOP instances, such as ophthalmic axial measurements SOP Instances or refractive measurements SOP Instances. If this occurs, a reference to the SOP instances is desired in attribute Referenced SOP Sequence (0008,1199).
