TRANSCRIPT
The BVA storyBuilding the bionic eye is a unique project, but like any medical device, it involves an iterative process bringing together the whole spectrum of expertise in our diverse team.
Bionic Vision Australia (BVA) is a national consortium of researchers working together to develop a bionic eye.
Our goal is to develop safe and effective retinal implants that can restore a sense of vision to people living with blindness. We are targetting two conditions: retinitis pigmentosa and age-related macular degeneration.
We are committed to training the next generation of experts in medical bionics.
Step 1: Design prototypesResearchers are developing two bionic vision devices:
The wide-view device combines novel technologies with materials that have been successfully used in other clinical implants. This approach incorporates a microchip with 98 stimulating electrodes and aims to provide increased mobility for patients to help them move safely in their environment.
The high-acuity device incorporates a number of exciting and new technologies to bring together a microchip and an implant with 1024 electrodes. The device aims to provide functional central vision to assist with tasks such as face recognition and reading large print.
Step 2: Establish safety and efficacy The design process goes hand in hand with ongoing safety and efficacy testing. This is a critical part of the project, to ensure that each design iteration is bringing us closer to delivering the best patient outcomes. This work involves vital feedback from the clinical and surgical teams and ensures our devices are compliant with Australian and international standards.
Step 3: Commence first patient testsOur ultimate goal is to improve the quality of life for people with degenerative vision conditions. We plan to carry out the first prototype human implant in 2013. Following successful patient tests the commercialisation process will commence.
