During the refraction measurement, the necessary correction is established: the spherical power (in diopter), the cylindrical power (in diopter), the axis direction(in degrees) for any cylindrical correction, the prism (in diopter)and any additional power of the reading area (in diopter), the so-called reading addition #### Purpose The purpose of a refraction measurement is to determine the correction (through glasses or lenses) with which the patient can see optimally. #### Patient Population Adults and children from the age that they can interpret a picture chart."> <extension url="http://hl7.org/fhir/StructureDefinition/translation"> <extension url="lang"> <valueCode value="nl-NL" /> </extension> <extension url="content"> <valueMarkdown value="De refractiemeting is een meting waarbij de brekingsafwijking van het oog wordt bepaald. Bij de refractiemeting wordt de benodigde correctie bepaald: de sferische sterkte (in dioptrie),de cylindrische sterkte (in dioptrie), de asrichting (in graden) voor de eventuele cilindrische sterkte , de prisma (in dioptrie) en de eventuele extra sterkte van het leesgedeelte (in dioptrie) , de zogenaamde leesadditie. #### Purpose Het doel van een refractiemeting is het bepalen van de correctie (door middel van bril of lenzen) waarmee de patiënt optimaal kan zien. #### Patient Population Volwassenen en kinderen vanaf de leeftijd dat ze een plaatjeskaart kunnen interpreteren." /> </extension> </extension> </description> <copyright value="Copyright and related rights waived via CC0, https://creativecommons.org/publicdomain/zero/1.0/.
