Pixium Vision Implants Restore Sight in Rats with Retinal Degeneration, Humans Next (VIDEO)
Prima Vision, a company based in Paris, France, is reporting that its PRIMA wireless subretinal implants for people who lost their vision has show a great deal of promise in a pre-clinical trial. The technology is designed specifically for those whose natural photoreceptors no longer function, yet who retain retinal neurons that can be electrically activated. A bunch of the implants are injected into the back of the eye, each around 70-μm in width that represents a single pixel. The implants are basically tiny photovoltaic solar panels that emit electricity in response to light hitting their surface.

Eyenuk EyeArt Software Automatically Screens Fundus Images for Signs of Diabetic Retinopathy
Eyenuk, a Woodland Hills, California company, won the European CE mark for its EyeArt software that analyzes images of the retina taken using fundus cameras to help detect diabetic retinopathy (DR). The software requires nothing more than a well produced color retinal image and has shown a sensitivity of detecting DR often better than human professionals.
EyeArt is able to process entire batches of images, going through thousands in a matter of hours. This may allow entire populations to be screened for DR, hopefully saving many eyes and improving lives.

KAMRA Inlay Corneal Implant to Replace Reading Glasses FDA Approved
Owning reading glasses is a part of growing up, but for many people that start wearing them in their later years it can be downright awkward and uncomfortable. Now a new device, just approved by the FDA, may offer certain folks with presbyopia a new way of addressing the condition.
The KAMRA inlay from Acufocus (Irvine, CA) is implanted into the cornea of one of the eyes of the patient, leaving the second one untouched. The device is essentially a 3.8 mm ring with a 1.6 mm aperture in the center. Just like a diaphragm in a camera, having a narrow opening for light to pass through increases image focus. Of course a lot of the peripheral unfocused light is blocked by the implant, but because only one of the eyes gets it, patients will maintain distance vision without losing depth perception.

Eye Lenses Designed With Significantly Reduced Halo Effect
Extended depth of focus and multifocal lenses, including contact and intraocular ones, tend to create a halo effect in certain light conditions. It can be distracting and even dangerous, particularly at dusk and night when looking at bright point sources such as traffic lights. Researchers from Bar-Ilan University in Israel have come upon a way of substantially reducing this halo effect without making the manufacturing of the lenses any more difficult.
The technique requires a precise smoothing of the structures on the surface of the lenses. This was achieved by initially building a mathematical model of how light has to pass through the lens, followed by numerical simulations, and then actually creating the lenses. These were then implanted in 16 volunteers who rated the halos they saw. Impressively, the results demonstrated a substantial reduction in the size of the halos compared to commercially available lenses.

IRIS Fundus Camera Automatically Spots Eye Conditions (VIDEO)
Intelligent Retinal Imaging Systems, a company out of Pensacola, Florida, received FDA clearance for its IRIS automated fundus camera for screening patients for diabetic retinopathy, macular edema, glaucoma, and other eye related conditions. The device, the first of its kind, doesn’t require professional ophthalmologists to operate it, but does capture imagery of the back of the eye that is then processed to detect suspected conditions. The process takes about 15 minutes per patient. The retinal images of patients with potential abnormalities are then forwarded to professionals who can make diagnoses or recommend further screenings.
