Abstract
The apparatus for correction presbyopia comprises a photorefractive surgery laser beam device operating by means of a control program capable of managing the following instructions: extent of at least a first circular area of intervention, which determines at least first laser beam aiming parameters; at least a first depth of intervention in the first area of intervention, which determines at least first intensity and/or duration parameters for the laser beam; at least a first activation of the laser beam with the first aiming parameters an the first intensity and/or duration parameters; extent of at least a second circular area of intervention, concentric, superimposed and with a diameter different from the first area of intervention, which determines at least second laser beam aiming parameters; at least a second depth of intervention in the second area of intervention, which determines at least second intensity and/or duration parameters for the laser beam; and at least a second activation of the laser beam, following on from the first activation, with the second aiming parameters and the second intensity and/or duration parameters.

- A method of correcting presbyopia by operating a photorefractory surgery laser beam device to emit a laser beam by means of a program controlling said device, comprising the steps of;
determining an extent of at least a first circular area of intervention, which determines at least first parameters for aiming said laser beam;
determining at least a first depth of intervention in said at least first area of intervention, which determines at least first intensity and/or duration parameters for said laser beam;
activating at least a first activation of said laser beam with said first aiming parameters and said first intensity and/or duration parameters;
determining an extent of at least a second circular area of intervention, concentric, superimposed and with a diameter different from said first area of intervention, which determines at least second parameters for aiming said laser beam;
determining at least a second depth of intervention in said at least second area of intervention, which determines at least second intensity and/or duration parameters for said laser beam; and
activating at least a second activation of said laser beam, following on from said first activation, with said second aiming parameters and said second intensity and/or duration parameters. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
