| description | Refractive power measurement increment is the specificity to which a keratometer can measure the refractive power, typically 0.25 diopters, but may be as small as 0.01 diopters. For example, a 0.25 diopter increment allows measurement of 0.25, 0.5, 0.75, 1.0 diopters, etc., while a 0.01 diopter increment allows finer measurement to a hundredth of a diopter. | |

| component | Refractive power measurement increment | |
| property | Type = Type: The Property Type is used for assays that identify the specific analyte in cases when the baseline presence of the analyte is known. | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
| system | Keratometer | |
| scale | Nom = Nominal: Nominal or categorical responses that do not have a natural ordering. (e.g., names of bacteria, reported as answers, categories of appearance that do not have a natural ordering, such as, yellow, clear, bloody. | |
