Table C.8.25.16-8 specifies and describes the attributes for the Cornea Measurement Macro used in IOL calculation.

**Table C.8.25.16-8. Cornea Measurement Macro Attributes**

Steepest meridian as defined by the greatest power of curvature and shortest radius of curvature. |
|||

The radius of curvature of the principal meridians of the cornea, measured in mm. |
|||

The refractive power of the cornea at the principal meridians, measured in diopters. |
|||

The meridian where the radius of curvature or corneal power is measured, in degrees. |
|||

Flattest meridian as defined by the least power of curvature and longest radius of curvature. |
|||

The radius of curvature of the principal meridians of the cornea, measured in mm. |
|||

The refractive power of the cornea at the principal meridians, measured in diopters. |
|||

The meridian where the radius of curvature or corneal power is measured, in degrees. |
|||

The translation factor specific to each keratometer that derives a number for power from the measured radius of curvature of the cornea. |
|||

The refractive translation factor specific for the cornea when deriving a number of power from the measured radius of curvature of the posterior surface of cornea. Required if Cornea Measurement Type Code Sequence (0046,0116) contains an item with the value (DCM, 111759, "Posterior Cornea Surface Measurement"). |
|||

The refractive translation factor specific for the aqueous humor when deriving a number of power from the measured radius of curvature of the posterior surface of cornea. Required if Cornea Measurement Type Code Sequence (0046,0116) contains an item with the value (DCM, 111759, "Posterior Cornea Surface Measurement"). |
