WASHINGTON: Doctors in US have successfully implanted an artificial retina in two near-blind patients to allow them to see objects, light and people standing before them.
Thiran Jayasundera and David N Zacks, from the University of Michigan Kellogg Eye Center performed the surgeries for patients with end-stage retinitis pigmentosa (RP), a degenerative and blinding eye disease.
"We are pleased with both patients' progress at this point, and we are hopeful and optimistic that the artificial retina will enable them to see objects, light and people standing before them," Jayasundera said.
"We believe the device will help them navigate a little better at home, be more independent, and have the pleasure of seeing things that the rest of us take for granted," said Jayasundara.
The device Argus II Retinal Prosthesis System was approved by the US Food and Drug Administration last year. The retinal prosthesis is not activated until the patient has sufficiently recovered from surgery.
The patient then undergoes training to adapt to the new vision, a process that can take from one to three months.
