  • Patent number: 10898073
    Abstract: Optoelectronic binocular instrument for the automatic correction of presbyopia and method for the binocular correction of the presbyopia. The instrument has two optoelectronic lenses (103, 110; 203, 204) and a capturing subsystem for taking images of the eye. By means of the pupil tracking, which performs the processing of the eye's images, the system determines the distance where the subject is looking at. The pupil tracking works at a very high speed, using a high-performance graphic processor and a highly parallelized algorithm for pupil tracking. The method consists of two phases. In the first one a calibration is accomplished, the subject is asked to look at targets at different distances and the size and position of the pupil is measured. In the second phase the correction is performed by the instrument, the system continuously captures and processes images to calculate the correction to apply and, finally, corrects the presbyopia by applying said correction.

  • Publication number: 20030086063
    Abstract: A wavefront aberration of an eye is determined, e.g., in real time. The eye is illuminated, and the light reflected from the retina is converted into spots with a device such as a Hartmann-Shack detector. The displacement of each spot from where it would be in the absence of aberration allows calculation of the aberration. Each spot is located by an iterative technique in which a corresponding centroid is located in a box drawn on the image data, a smaller box is defined around the centroid, the centroid is located in the smaller box, and so on. The wavefront aberration is calculated from the centroid locations by using a matrix in which unusable data can be eliminated simply by eliminating rows of the matrix. Aberrations for different pupil sizes are handled in data taken for a single pupil size by renormalization.
