CA 2529813

Methods, devices, and systems for predicting an optical acuity measure of an optical system of an eye. An optical acuity measure can be predicted by determining a point spread function based on a wavefront measurement of an eye, convolving a resolution target with the point spread function to produce an image, and predicting the optical acuity measure of the optical system of the eye based on the image.

La présente invention concerne des procédés, des dispositifs et des systèmes qui permettent de prédire une mesure d'acuité visuelle du système optique d'un oeil. Selon l'invention, on peut prédire une mesure de l'acuité visuelle en déterminant une fonction d'étalement ponctuel sur la base d'une mesure de surface d'onde d'un oeil, en convolutionnant une cible de résolution avec la fonction d'étalement ponctuel pour produire une image, et en prédisant la mesure d'acuité visuelle du système optique de l'oeil sur la base de l'image.
