a group of degenerative diseases that affects up to one in 3000 people and with no cure currently available it can result in a slow and complete loss of vision i'm dr janet abdomen and amsterdam the netherlands to see how an incredible new implant is giving people who are completely blind the chance to see again. fred van rennie's is one of 70 people around the world who are being fitted with the august 2 retinal prosthesis system a device that is giving back some sight to people suffering from certain types of blindness in the past i have seen i played football on the field kind of thinking i can walk i can only bicycle it was not in one time but in its own fairing very slowly by the time you were 34 you could not see yes i don't know. your wife tanya have you ever seen her face yes. when i was 34

and she was 29 i'm not 58 years old in my mind she is still 29 years old i get that you know i thought you played out how do you feel being only the 3rd person in the country to have this. yes this. is the surgeon who will be operating on friday. it's exciting technology that is basically a little microchip we implant in the eye. blind people that are affected by everything like this because those are thanks to this. light in a healthy i the photo receptors in the retina converts light into electro chemical impulses that are sent through the optic nerve and into the brain condition such as retinitis pigmentosa can stop the photoreceptors from working properly the argus to bypass is these damaged photo receptors using

a miniature video camera that sits on the patient's glasses this camera sense wireless signals via video processing unit to an implant which has been surgically placed on the damaged retina the implant then emit small pulses of electricity which travel along the optic nerve to the brain which learns to interpret these pulses as visual patterns when you begin to question but do not understand what they're saying is an artificial vision so they have to out with the pattern of light we send them because it's not the vision we have but what we're used to. love. during the surgery dr moreau will pin the electrode to the back of the eye which in turn will be attached to an aerial that will wrap around the i have

a real it's being anchored to the outside of the white it's just being on the hook and from the model it won't be seen when you look at the behind behind it. the complexity of the operation means the surgery can take up to 4 long hours. christopher firing white being. which is. he came right. through that he's the hero. of the moment of truth with. that faction of that group and pretty much. now. you know. who most done you happy with it yes that meant. plenty of these plays you said to still it might be. you didn't but it is another patient would want to not just pick mentos so who had

the device implanted 4 months ago. i love that i want your room i'm fine i think you have a job and just to be nice if you want to hear adult stuff that's exactly what i was 11 when i got diagnosed and yeah and when i was was 15 it get worse and worse and i think again not a bicycle anymore and yeah and when i was 18 and 19 in 2 years i lost 80 percent of my official feels it's only been 4 months since it's been 4 months it takes it takes a lot of time and you know i've got 3 film to wish and the 1st long days with 6 packs. and that's for when the conversation i had went to school whether and when it's cloudy or whether i used this one and i got 12 with extra contrast and when it's too cloudy i use this one i'm sure that you could get infrared heat seeking just a touch of. it's

a lot of preparation just in improving when i do this yeah i see this you can see that there's life lessons oh wow. when i do this i can see i can see and can you see can you see exactly i see light and. i don't see how many you are so you can actually tell there are stripes that i know that they're oh yeah i see their stripes. when you go stand over here. and it's gets it's going to much much better you know not show a little you know if i could see it it's got above me like yeah you know when i do this. i see exactly where it's going now if now you're standing in the right in the right leg so i can scan you and you can scan megs i actually. i now see something moving when. when when they're walking i see something moving

so you know it's you know a little i need a big big so you can tell the difference to people in that sense you know. even in the 4 months he's had the device it's great to hear the difference it's made to your rooms life while my orientation is it's a little bit better i feel safer and i'm more confident now. that. 2 weeks after the surgery fred has recovered enough to have the device turned on for the 1st time jessica nice to meet you you excited about today. yes a little bit from what we did yes what you hope to achieve this afternoon i hope. that i see your face ok. so you are as well you are well good looking. well us here at the glasses with the camera ok i'm recording transfer me. to the cable through to feed you and if you sense it

back to the call. i think it would be a video processing unit or something else yes. you know to turn off. all that. just. because. it's turned. in your. room. i think i. cannot show you what i. think you're called for its brain has to learn to process this as if you touch it and that will take time so you just try to listen to you we'll see and hear on the screen there's an approximation of what the cameras are so if you can hear to move around friends. i see myself on the computer.

he sees the peaks but the still desert and just over water with me it's my brain so i thought. you know it's been asleep for a while it's time to wake up. a huge part of the process for fred is to practice with a device so that his brain can learn to understand the signals it's receiving 4 months after it was 1st switched on i'm excited to see how he's getting on and i think i've prayed. for months exactly almost yes indeed it has a bit you want you want to know what but happened all the time. when we were going home at home i said all the trees that i dove to we're really out of the tree restless and all that and i don't rush out and at home and when we put on the light in our house also ready i see all the lights. that fell.

well amazing and on the set today she was sitting at the dinner table and i was chatting year and that's all. it was and i didn't fail a moment to do a great yeah yes it's a technique you know and. a lot of times you do one step back and doing steps forward. your if you had lost sight ok find out what your have just turned your head you know you have to lift the cap a friend of 1st a beginning but the beginning you're benefiting and ok yeah there's a clear point it could go to. the center that's my. ok there is something you're good to see and you can pinpoint is there it is but if you see now in the last 2 times see improvement already set improved so extremely

so the sky's the limit very good. got a little just not straight don't follow the. me very quickly to promote this. friend you just seen a pyramid a few months ago you saw last thing i think it's amazing. fred's brain will continue to learn to process the signal so there's no knowing how much insight will improve and at the same time scientists are developing the technology and software involved for people who have been living in darkness for so long the potential impact of this is enormous. discover new developments in surgery. in hiroshima japan to meet the surgeon
