3. A method for improving presbyopic patient's vision by removing a portion of the sclera tissue from an eye of a patient, said method comprising the steps of [ accommodation and/or treating presbyopia, the method comprising] :
selecting an ablative laser for removing sclera tissue by focusing said ablative laser to a spot size of about (5-800) microns on the corneal surface;
selecting a scanning mechanism for scanning said ablative laser;
coupling said ablative laser to a scanning device for scanning said ablative laser over a predetermined area outside the corneal limbus to remove said sclera tissue [ ;
removing sclera tissue from outside the corneal limbus area, said removing comprising forming a pattern of radial lines in the sclera to a depth of 500-600 microns, ] whereby a patient's near vision is improved by the increase of the corneal lens accommodation.
