A treatment apparatus for surgical correction of presbyopia or defective eyesight in an eye of a patient. The treatment apparatus includes a laser device configured to treat lens tissue of the eye by irradiation of pulsed laser radiation with the laser radiation being focused on target points arranged in a pattern within the lens. An interface supplies measurement data on parameters of the eye and/or defective-eyesight data on the eyesight defect to be corrected in the eye, and defines a volume located within the lens using the supplied measurement data and defective-eyesight data, the volume being defined so as to achieve the desired correction of presbyopia or defective eyesight when removed.

Device and procedure to treat presbyopia

Visual displays of the geometry and/or topography of a portion of the eye is obtained from data generated during a number of angularly spaced scans taken across a meridional coronal section or of a marginal sector of the anterior surface of the eye, the data being processed for display, to thereby permit the optimization of the surgical placement and the configuration of lenses.
