About your sister; her viewpoint does not strike me as particularly healthy. For 20+ years I've been told that science would cure my macular degeneration, and my mother was told the same thing about HER eyes for 20+ years before me. Living life waiting for a cure is unhealthy, as it can lead to depression when that cure doesn't arrive, and unproductive for obvious reasons.
I read articles like this and take them with a grain of salt. They're neat little curiosities, but they get shoved in the same mental pile as all of the stories about terahertz processors, holographic memory, and privatized spaceflight that we'll have "some day Real Soon Now." So don't hold your breath.
A bit of advice (which I'm sure she's heard a hundred times before) for your sister; don't wait for a cure. Assume that it's never going to happen, and get on with your life. It's a whole lot easier than you think.

For me with a history of retinal detachment since the age of 22 this is good news indeed. Fixing the retina by installing a pea-sized bit of silicone inside the outer layer of the eyeball is such a medical kludge...
Re:Great news for people with retinal ablation (Score:2)
The question I have about your comment however is: if your retina is detaching, wouldn't this technology be just as ineffective as your existing retina?
This seems to be a pretty invasive procedure and might even make your problem worse as the retina is 'elevated' to insert the arrays.
This could probably speed or complicate your problem based on the type of retinal detachment you have. (more information on retinal detachment here: http://www.vrmny.com/retinal_detachment.htm [vrmny.com]
Re:Great news for people with retinal ablation (Score:1)
Regarding my operation, the retina was reattached in the corrective surgery but I was told that it could start coming off again in the future.
In my case I was given a choice between a "quick-and-dirty" laser fix and a more thorough surgery ("Scleral buckle" on the page you linked to). In the former treatment the borders of the detached area would be burnt with the laser to prevent further degradation, but the results would not be as good. In fact, if the detachment continued after the burn-in the resulting damage would become even more severe than without the operation.
Re:Great news for people with retinal ablation (Score:1)
Further damage is avoided by reducing the chance of hemmorage in the eye and the susequent scar tissue which tore the retina before.
This article mentions the brain compensating for the new voltages the implant provides. Given that my good eye is usually 20/20, I hope subjects like myself are used in this study.
Re:Great news for people with retinal ablation (Score:1)
As far as I know that's the stuff they used to fix my retina.
It's a completely passive fix. First they cut open the outer layer of the eye (the white stuff) at the point of the retinal detachment. Then they create scar tissue with a cold probe cooled with liquid nitrogen to roughen up the inside of the eye. Finally they insert the pea-sized silicone piece in the cut to press the now rough background of the eye against the retina. The idea is that the scar tissue inside the eye hooks up with the detached retina. If I lift my eyelid I can see the silicone piece underneath the scar.
It was a surprisingly painless operation. A full anesthesia during surgery and about a week in the hospital with only moderate pain medication (first a nerve block and later codeine and paracetamol).

And the best thing... I dont really see how this technology could be abused. Many other implants and biotech research projects are accused of being too much sci-fi (stem cell research, organ transplants, organ growth etc).

I think the most difficult part about this is how the nerves will react. I think they're very right about the brain needing training to adapt to this. I'm pretty confident it could do it, but I don't know how much training it would take.
I thought the process with the dissolving film was an incredible idea too.
I hope this one pulls through. Does anyone with a neuroscience background have any thoughts on the feasibility of this one?

I think if they are there though, the training would be critical. I don't think they would properly line up initially, as you've said. My guess though, is that the brain would eventually rewire things (maybe downstream from the brain too) to sort out the image correctly. That would be the training phase. The fact that the brain can massively rework itself to recover from trauma indicates to me that this is possible.
Once again, I'm no neuroscientist (I've decided that in biology there are neuroscientists and everyone else, and I'm in the latter category) but I have a fair amount of faith in this if it works as well as they say. The problem would be the time and effort to train the person to see correctly.

It took people some hours to adjust, but then they could react properly again to their environment (walking and the like).
So, yes, our visual cortex is very flexible to unexpected visual stimuli modifications, and seems to adjusts in a relatively short time...

Long term testing needs to be done too; since the eyes deteriorate with age (which can adversely affect the results of current corrective surgery, such as LASIK where if you get it done too soon, you'll need glasses again by the time you're 35-40) I'd love to know what will happen to this technology.
Don't get me wrong; it's way cool. But these are my eyes, dammit!
Re:How long... (Score:4, Informative)
It's true that if you have LASIK surgery you may require glasses again when you are older, but this is due to the natural aging process of the eye, not the LASIK surgery. Your risk of needing reading glasses when you're old remains exactly the same as if you never had any eye surgery.
Your eye has special muscles that reshape the curve of your eye's natural lens. These muscles weaken over time, and can't change shape to focus on objects near to you. This is what reading glasses correct, and is a different problem than what LASIK corrects.

I used to want those, but now I've upped my sights (so to speak). Now I want tinted contact lenses that change into "sunglasses" in bright light, like those variable-tint "sun sensor" glasses. They'd basically be enhancing the degree to which your iris can vary the amount of light that gets into your eye -- that'd be a "bionic" device I'd happily pay for.

The question of availability has already been asked, and the answer clearly is in a long long time. I'm glad to hear they found some desperate person to accept to test the technology as soon as 2002 (don't misunderstand me, I'd be desperate too if I lost my eyes), but come on. It won't work right the first time, nor the second. And then they'll have to conduct large-scale studies to optimize the huge amount of parameters and tunings such operations involve. I don't expect such operations becoming common before ten or twenty years.
But moreover, how much will this cost? Ultra-thin ceramic films don't grow on trees, and I'd be surprised they'd become cheap, relatively speaking, anyday soon. Besides I guess that people able to put millimeter-sized implants at the back of the eye are not selling their skills for free, far from it. I think only a few crazy millionaires will have a chance to try it in the next few years, if even they dare, or their insurances allow them.

I mean geez, that noise got old fast, not to mention that it makes it hard to be discrete when you're using your bionic vision on the hot chick standing next to you.

On another note, the article doesn't say anything about whether the arrays act more like rods (high-speed night vision) or cones (high-detail colour images). Or does it act like a video camera? It would also make sense to implant the array near or on the fovea (center of the retina, all cones only), so that the array produces the images in the center of the person's vision. If the implant wasn't at the fovea, they would seem to be looking away from you when they're actually looking at you. Also, if the implant acted more like rods, this could be weird for the person.
But all this talk of cutting open the eye and doing all that squishy stuff freaks me out too.

Space as a research environment (Score:1)
Dr. Ignatiev at the University of Houston [uh.edu] is in charge of a NASA-funded effort to develop "Space Vacuum Epitaxy", where researchers try to take advantage of the vacuum of space as a growth environment. The problem is, near-earth space simply isn't low enough pressure to work well, meaning that the researchers need to have their experiments behind a "wake-shield" - basically a big metal plate that pushes unwanted gas molecules out of the way.
The upshot is that space vacuum epitaxy is hugely expensive. Better and more controlled vacuums may be achieved on earth at a tiny fraction of the cost of a single shuttle launch. While I'm glad NASA funds research efforts like this, many such projects, even while producing cool results, often end up with the conclusion that doing the work in space is neither necessary nor desirable.

Retinal research (Score:4, Informative)
Additionally, these studies are making several assumptions about the nature of retinal degenerations in that bionic based implants will be able to successfully interface with the ganglion cells or the output cells of the retina. I have read nothing that examines the field effects of these chips. In other words, how do we know that when these chips are activated that they just stimulate the ganglion cells? Basic physics tells us that there should be field effects that also might influence amacrine cells, horizontal cells, remaining bipolar cells etc...
The other assumption that almost no-one in the visual research community has addressed is the intrinsic circuitry of the retina in cases of retinal degeneration. The underlying assumption is that in retinitis pigmentosa and macular degenerations the photoreceptors degenerate from a variety of primary insults (genetic and environmental) and the rest of the retina remains relatively intact. Preliminary research by myself and others indicate that this is NOT the case. The retina continues to degenerate and remodel itself with large numbers of retinal cell subclasses that dissappear and move into other layers of the retina among other dramatic changes.
This does not neccessarily shut the door on retinal transplantation research, rather it indicates that there are other issues that need to be addressed and straightforward transplantations (biologic and bionic based) are not neccessarily going to work in the short term. I think eventually they will work with a combination of pharmacotherapy and/or gene therapy, but we are probably 50 years or more off. Therefore in response to another poster who has a family member who suffers from retinitis pigmentosa and refuses to learn braille, I would suggest that she does not hold out hope that a cure will be just around the corner and make the effort to learn braille and use other methods such as computer mods with large text etc... to compensate.
