The second version, the Argus II, was designed to be smaller and easier to implant, and was co-invented by Mark Humayun of the USC Eye Institute, who had been involved in the clinical testing of the Argus I. [12] [11] The Argus II was first tested in Mexico in 2006, and then a 30-person clinical trial was conducted in 10 medical centers across ...
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
Humayun co-invented the Argus II retinal prosthesis, [23] a retinal implant designed to help patients with genetic retinitis pigmentosa. [ 24 ] [ 25 ] More than 30 clinical trial participants in Argus II trial launched in 2007 at sites in the U.S. and Europe.
The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy ...
In February 2013, the US Food and Drug Administration approved the use of the Argus II Retinal Prosthesis System , [11] making it the first FDA-approved implant to treat retinal degeneration. The device may help adults with RP who have lost the ability to perceive shapes and movement to be more mobile and to perform day-to-day activities.
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
Photovoltaic retinal prosthesis is a technology for restoration of sight to patients blinded by degenerative retinal diseases, such as retinitis pigmentosa and age-related macular degeneration (AMD), when patients lose the 'image capturing' photoreceptors, but neurons in the 'image-processing' inner retinal layers are relatively well-preserved.

The trademarked "Natural Yellow" material is available in three hydrophilic IOLs. Dr. Patrick H. Benz of Benz Research and Development created the first IOL material to incorporate the same UV-A blocking and violet light filtering chromophore that's present in the human crystalline lens in order to attempt to protect the retina after cataract ...
