Embodiment Construction

[0040] The present invention uses a computer-guided scanning system to apply a pattern P of points S on a trabecular meshwork (TM), where the alignment of the pattern on the TM by the scanning system ensures that successive patterns fit together without overlap or excessive gaps to provide a continuous pattern of treatment light around the TM. This scanning system uses many of the same basic components as shown in FIG. 3 (and described in U.S. Published Application 2005 / 0288745 A1, which is hereby incorporated by reference), with the following exception: Rotation of the gonioscopic mirror is performed by the physician. Manual controls, and the geometry of the system and precise rotation of the alignment / processing pattern by the scanning system are configured to provide the physician with the vision needed to ensure the desired amount of movement of the gonioscope between successive pattern applications Guided, this desired amount will result in the split pattern P of light be...

Abstract

A system and method of performing therapy on target eye tissue. A light source produces a beam of light, and a scanning device deflects the light beam to produce an pattern of the light beam. An ophthalmic lens assembly includes a mirror for reflecting the light beam pattern onto the target eye tissue. The mirror is rotatable to angularly align the light beam pattern to the target tissue. Controlelectronics control the scanning device to apply the light beam pattern onto the reflective optical element at first and second angular orientations separated by a predetermined angle RA. The predetermined angle RA is set such that light beam patterns applied to the target tissue at the first and second angular orientations, which are also angularly aligned to the target tissue through rotation ofthe mirror, automatically are adjacently abutting to each other on the target tissue.

Description

[0001] related application [0002] [001] This application claims the benefit of US Provisional Application No. 60 / 906,992, filed March 13, 2007, which is hereby incorporated by reference. technical field [0003] [002] The present invention relates to the treatment of glaucoma, namely laser-based trabeculoplasty, and more particularly to computer-guided laser trabeculoplasty. Background technique [0004] [003] Glaucoma is well known to be a potentially debilitating group of ophthalmic diseases with a high risk of blindness. These conditions include, but are not limited to: open angle glaucoma, angle closure glaucoma, neovascular glaucoma, normal tension glaucoma, exfoliation and pigmentary glaucoma. Common in all of these conditions is the inability of the eye to adequately balance the secretion of the aqueous humor from the ciliary body with its removal through the trabecular meshwork (TM), thereby raising the internal intraocular pressure (TOP). High intraocular press...
