Table C.8.25.16-5 CALCULATED IOL MACRO

Attribute Name Tag Type Attribute Description
IOL Manufacturer (0022,1093) 1 Name of the manufacturer that produced the lens.
Implant Name (0022,1095) 1 The (product) name of the lens.
Lens Constant Sequence (0022,1092) 1 Constants used in calculation of intraocular lens power. These constants are a characteristic of the model of intraocular lens being considered for use in cataract surgery. One or more Items shall be included in this sequence.
>Concept Name Code Sequence (0040,A043) 1 Constant type used in calculation of intraocular lens power. Only a single Item shall be included in this sequence.
>>Include 'Code Sequence Macro' Table 8.8-1. Defined Context ID is 4237
>Numeric Value (0040,A30A) 1 The value of the constant used.
IOL Power Sequence (0022,1090) 1 Information needed to select the intraocular lens power for cataract surgery. One or more Items shall be included in this sequence.
>IOL Power (0022,1053) 1 The intraocular lens power, in diopters.
>Predicted Refractive Error (0022,1054) 1 The predicted postoperative refractive error (i.e. amount of near or far sightedness), in diopters.
>Implant Part Number (0022,1097) 2 The (product) identifier of the lens.
IOL Power for Exact Emmetropia (0022,1121) 2 The IOL power that would be required to achieve exact emmetropia, or no need for glasses at distance after surgery, in diopters.
IOL Power for Exact Target Refraction (0022,1122) 2 The IOL power that would be required to exactly achieve the Target Refraction (0022,1037), in diopters.
