Noteworthy news from medtech start-ups. This month we profile three emerging artificial retina developers: Nano Retina, 2C Tech Corp. and LambdaVision.

Artificial retinal prostheses are poised to make a dramatic impact by restoring at least partial vision to people blinded by degenerative ophthalmic diseases. A number of companies are developing complex implantable microelectronic innovations, many with external hardware components, to stimulate the retina and overcome the photoreceptor cell deterioration that is the hallmark of these diseases. LambdaVision Inc. is taking a unique approach to restoring vision by developing a flexible, protein-based retinal implant designed to provide higher resolution and to be less surgically invasive than competing technologies.

A look back at the biggest devices stories of the decade, in capsule form.

Brief summaries of recent advances in device research and clinical trials, including a promising new retinal implant and new findings in the field of radiation therapy.
