Patent ID: 7496174

Claim:
A method, of treating an eye of a patient, comprising: providing a geometric representation of the eye, based, at least in part, on anatomic data obtained by an imaging apparatus; producing a first x-ray beam and a second x-ray beam, each beam having a width of less than about 6 mm; directing the first x-ray beam such that the first beam passes through a first region of a sclera of the eye to a target of a retina; and directing the second x-ray beam such that the second beam passes through a second region of the sclera to substantially the same target of the retina as the first beam, wherein the first region and second region of the sclera are selected based on the geometric representation of the eye; and wherein the first and second x-ray beams are directed such that central axes of the first and second x-ray beams are projected through the sclera at a distance of from about 0.5 mm to about 6 mm from a limbus of the eye.
