Part Description

LP420716-5   Prism base direction
Corrective lenses use prism to adjust image perception with both eyes to a single fused image. Each lens may have a horizontal, in (towards the nose) or out (towards the temple) and/or vertical, up or down, prism base. Prism measurements are reported in X-Y orthogonal coordinates (horizontal in/out, vertical up/down) or P-B polar coordinates (prism plus the angle of the prism base direction). Prism lenses are commonly used to treat diplopia and strabismus. Source: Regenstrief LOINC

Change Reason
Release 2.71: PROPERTY: Update from "InvLen" to more accurately represent the concept of the direction of the prism base in degrees (0 to 359); COMPONENT: Updated "distance" to "direction" to more accurately represent the concept of the direction of the prism base; Status: Changed Status from Deprecated because this term is being used in the ISO specification for Ophthalmic examination device data ; Release 2.69: SHORTNAME: Term was ambiguous. Component and System were incongruous .;
