What are the differences between all the power maps displayed by the Pentacam\u00ae?<\/p>\n
Different corneal power maps are displayed by the Pentacam\u00ae:<\/p>\n
– Sagittal and Tangential Power map
\n– Refractive Power map
\n– True Net Power map (TNP)
\n– Total Corneal Refractive Power map (TCRP)<\/p>\n
Pentacam\u00ae measures height (elevation) data. These are converted into curvature (mm) and then converted into power values (diopter).<\/p>\n
Different factors are taken into consideration to calculate the different power maps of the Pentacam\u00ae:<\/p>\n
– The refractive effect (Snell\u2019s law of refraction)
\n– Inclusion of anterior\/posterior surfaces
\n– Correct refractive indices used
\n– Location of principle planes (Ray tracing)<\/p>\n
Refractive effect ; Inclusion anterior\/posterior surface; Correct refractive indices used; Ray tracing<\/p>\n
Sagittal map; Refractive power map; TNP; TCRP<\/p>\n
Above table shows the factors used to calculate the different power maps. \u00bfCu\u00e1les son las diferencias entre los mapas de la potencia que muestra el Pentacam\u00ae?<\/p>\n
El Pentacam\u00ae muestra diferentes mapas de la potencia corneal:<\/p>\n
– Mapa de la potencia sagital y tangencial
\n– Mapa de la potencia refractiva
\n– Mapa True Net Power (TNP)
\n– Mapa Total Corneal Refractive Power (TCRP)<\/p>\n
Pentacam\u00ae mide los datos de la altura (elevaci\u00f3n). Esta informaci\u00f3n se convierte en curvatura (mm) y despu\u00e9s en valores de potencia (dioptr\u00eda).<\/p>\n
Para calcular los diferentes mapas de la potencia del Pentacam\u00ae se tienen en cuenta diferentes factores:<\/p>\n
– El efecto refractivo (ley de refracci\u00f3n de Snell)
\n– Inclusi\u00f3n de las superficies anteriores\/posteriores
\n– \u00cdndices de refracci\u00f3n correctos utilizados
\n– Ubicaci\u00f3n de los planos principales (trazado de rayos)<\/p>\n
Efecto refractivo ; Inclusi\u00f3n de las superficies anteriores\/posteriores; \u00cdndices de refracci\u00f3n correctos utilizados; trazado de rayos<\/p>\n
Mapa sagital; mapa de la potencia refractiva; TNP; TCRP<\/p>\n
