Abstract
End-stage age-related macular degeneration (AMD) is defined as either bilateral advanced central geographic atrophy or untreatable disciform scarring from neovascular AMD. Profound loss of central vision leads to a dramatic reduction in quality of life for the 1.75 million individuals in the USA with diagnosed AMD. Despite novel therapies for patients with active neovascular AMD, there exists no treatment for end-stage AMD. The Implantable Miniature Telescope™ prosthesis received US FDA approval in July 2010 for treating severe-to-profound vision impairment (20/160 to 20/800 visual acuity) caused by bilateral central scotomas associated with end-stage AMD. The visual prosthetic is implanted into the lens capsule after cataract extraction to improve vision by reducing the size of the patient’s central scotoma in the implanted eye. Peripheral vision is maintained through the fellow eye. Results from a large multicenter clinical trial demonstrated that the visual prosthetic provided a ≥two-line improvement in visual acuity in over 90% of patients with an accompanying improvement in quality of life.
