Abstract

Un método para medir la presión intraocular bajo la superficie (202) de un ojo utilizando ondas electromagnéticas, en el que la radiación láser se dirige a la superficie (202) desde una distancia (200) para generar una vibración o una onda mecánica en la superficie (202) en al menos una localización de generación (204) en la superficie sobre la base de fenómenos fotoacústicos, siendo la localización de generación al menos un punto (204) donde la radiación láser golpea la superficie (202), las vibraciones de superficie debidas a la vibración o la onda mecánica generadas se detectan sobre la base de ondas electromagnéticas usando al menos una de entre una interferometría óptica, una tomografía de coherencia óptica y una vibrometría láser Doppler, la onda mecánica detectada se registra en al menos una localización de registro (206) para formar información de onda mecánica, y la información de presión de la presión intraocular bajo la superficie ocular (202) se determina basándose en al menos una señal registrada.
