Abstract

Se describe un tonometro mejorado que tiene un medio paquimétrico para medir un espesor corneal o de la cornea de un paciente para permitir la correccion de la medicion de la presion intraocular, donde la medicion del espesor corneal se desvía de un espesor corneal promedio de calibracion. En una modalidad preferida, una fuente de luz individual emite impulsos justo antes de la medicion de la presion intraocular, para iluminar una seccion corneal central, y un par de arreglos detectores de luz, laterales, se arreglan para reflejar oblicuamente la seccion corneal y para generar señales que se pueden procesar por un CPU para producir una medicion del espesor corneal. si la medicion del espesor corneal se desvía del espesor corneal promedio de calibracion, la CPU calcula una medicion de la presion intraocular, corregida por el espesor. La medicion de la presion intraocular, la medicion del espesor corneal, y/o la medicion de la presion intraocular, corregida, luego se pueden reportar por un medio de reporte.
