Abstract
An iridocorneal angle of the eye can be opened with a plurality of treatment locations at least about 2 mm radially outward from a limbus of the eye. The opening on the angle can be beneficial for treating both narrow angle glaucoma and open angle glaucoma. The plurality of treatment locations located away from the limbus can decrease invasiveness and complexity of the procedure. The plurality of treatment locations at least about 2 mm away from the limbus can provide tensioning to zonules coupled to the lens of the eye to flatten the lens of the eye, which can allow the iris to move posteriorly so as to open the iridocorneal angle. The plurality of treatment locations may comprise scleral locations, in which shrinkage of scleral tissue at the plurality of treatment locations provides tensioning to the zonules.
