LOINC code28684-9
nameDeprecated Visual acuity.binocular Eye Autorefractor.man
descriptionThe relative ability of the visual organ to resolve detail that is usually expressed as the reciprocal of the minimum angular separation in minutes of two lines just resolvable as separate and that forms in the average human eye an angle of one minute.
statusDEPRECATED
status reasonErroneous - Auto refractors do not measure visual acuity; they measure refraction error, which is a combination of cylinder, sphere and axis.
