Restoring Vision

At UI Health, our ophthalmology experts create new possibilities that help restore vision.

Argus II Retinal Implant

UI Health is one few centers in the United States to offer the Argus II retinal prosthesis to help restore vision in patients with retinitis pigmentosa (RP). RP is a rare, inherited eye condition that progressively robs eyesight, eventually leading to near- or total blindness.

The Argus II consists of a miniature camera housed in a pair of glasses that converts video images into electrical impulses that are transmitted wirelessly to an array of electrodes implanted on the surface of the retina. The pulses stimulate the retina’s remaining light-sensitive cells, which send signals through the optic nerve to the brain, where they are translated into images. Over time, patients learn to interpret the visual patterns with their retinal implant, allowing these patients to gain greater independence performing daily tasks.


Learning to See Again with the Argus II

In 2016, Robert Selby of Hazelwood, Missouri, was the first patient at UI Health to receive an Argus implant.

Says Dr. Jennifer Lim, director of the Retina Service at UI Health. "Its humbling and gratifying that after so many years of following the development of this kind of technology, that now I can see it work in one of my own patients."


PROSE: Prosthetic Replacement of the Ocular Surface Ecosystem

Our Contact Lens Service is the only Chicago-area provider and one of handful of sites in the U.S. that offers the BostonSight PROSE treatment to restore the sight of patients with complex corneal disease. During PROSE treatment, doctors custom design and fit prosthetic devices to replace or support damaged ocular functions — improving and restoring vision while reducing pain and light sensitivity.

The prosthetic devices created during PROSE treatment are transparent domes, about the size of a nickel. They look similar to an oversized hard contact lens and resemble a margarita glass without the stem in shape. Devices fit under the eyelids, vaulting the damaged cornea and resting on the sclera (the relatively insensitive white tissue of the eye). Worn during waking hours, patients are trained in daily application, removal and cleaning as part of the treatment process. The PROSE devices improve blurry vision by masking surface corneal irregularities and transmitting a sharp image to the back of the eye. PROSE reduces symptoms and supports healing by restoring a healthy ocular surface environment, and prevents damage by protecting the cornea against the environment and eyelids

Artificial Cornea Program

The Artificial Cornea Program at UI Health helps people with severe eye disease or injury for whom traditional corneal transplantation from human donors is not an option. Artificial cornea implantation, called keratoprosthesis, or k-pro, is a procedure designed to help patients whose conditions are the most difficult to treat. Our program is the largest program of its kind in the Midwest.
