TL;DR: Visual impairment appears to be better correlated with macula and optic nerve hypoplasia and the development of cataracts, glaucoma, and corneal opacification.
Abstract: ANIRIDIA IS AN uncommon bilateral disorder affecting not only the iris, but the cornea, anterior chamber angle, lens, retina, and optic nerve as well.1 Although iris hypoplasia is the most apparent clinical manifestation of the aniridic eye, it is not the major determinant of visual function. Visual impairment appears to be better correlated with macula and optic nerve hypoplasia and the development of cataracts, glaucoma, and corneal opacification.

TL;DR: In this paper, a predetermined pattern characterized by a plurality of positions along the plurality of spatially distributed iris tissues of an eye of a patient is obtained, and a laser illumination light beam is aligned in accordance with one or more of the plurality.
Abstract: Systems and methods of improving vision using an ophthalmological laser system are provided. A predetermined pattern characterized by a plurality of positions along a plurality of spatially distributed iris tissues of an eye of a patient is obtained. A laser illumination light beam is aligned in accordance with one or more of the plurality of positions along the plurality of spatially distributed iris tissues. The laser illumination light beam is delivered in the predetermined pattern to the plurality of spatially distributed iris tissues of the patient. At least a subset of the spatially distributed iris tissues is cauterized by the delivery of the laser illumination light beam in the predetermined pattern, thereby resulting in a permanent decrease in diameter of the pupil of the eye.
