The Argus II system costs about US$150,000, excluding the cost of the implantation surgery and training to learn to use the device. Second Sight had its IPO in 2014 and was listed on Nasdaq. [1] Production and development of the prosthesis was discontinued in 2020, [2] but taken over by the company Cortigent in 2023. [3]
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).
The Argus II is the retinal prosthesis the clinic used, and it allows some people who have lost their sight to. Allen Zderad saw his wife's face for the first time in a decade, thanks to a retinal ...
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.
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 Argus retinal prosthesis became the first approved treatment for the disease in February 2011, and is currently available in Germany, France, Italy, and the UK. [39] Interim results on 30 patients long term trials were published in 2012. [40] The Argus II retinal implant has also received market approval in the US. [41]
