Patent ID: RE40002

Claim:
A laser beam ophthalmological surgery method for treating presbyopic presbyopia in a patient's eye by ablating the sclera comprising the steps of: selecting a pulsed ablation laser having a pulsed output beam of predetermined wavelength; selecting a beam spot controller mechanism for reducing and focusing said selected ablative laser's output beam onto a predetermined spot size on the surface of the cornea eye ; selecting a scanning mechanism for scanning said ablative laser output beam; coupling said ablative laser beam to a scanning device for scanning said ablative laser over a predetermined area of the corneal sclera; and controlling said scanning mechanism to deliver said ablative laser beam in a predetermined pattern in said predetermined area onto the surface of the cornea eye to photoablate the sclera tissue outside the limbus to a depth of 80 - 90 % of the thickness of the scleral tissue , whereby a presbyopic patient's vision is corrected by expansion of the sclera.
