Wills Eye Gets Green Light for US Feasibility Study of Retina Implant’s Alpha AMS

August 3, 2018: By Joan McKenna

The US FDA has given Wills Eye Hospital the go-ahead to begin an early feasibility study of Retina Implant’s Alpha AMS subretinal implant in patients blinded by retinitis pigmentosa.

The prosthesis is designed to replace non-functioning and absent photoreceptor cells by stimulating the remaining components of the visual system to restore limited functional vision. The device’s chip has 1,600 photodiodes.

Germany-based Retina Implant gained CE marking for the Alpha AMS in 2016.

Wills Eye, based in Philadelphia, is the only study site in the US. The study will enroll up to eight patients. A larger pivotal study will follow if results are promising.
