Artificial Cornea To Reach Patients This Year 94

kkleiner writes "A German-led team of researchers has developed a new version of an ophthalmological polymer to which the eye will bond and still function normally. 'The new polymer could help restore sight to thousands waiting for corneal transplants around the world. The artificial cornea has passed clinical trials and is ready to see expanded use in patients this year. ... In order to work in the human body, an artificial cornea has to meet some stringent requirements. First, it has to bond to the human eye around its edge. ... The center of the artificial cornea, however, does not promote cell growth and remains clear so that it can be seen through. The artificial cornea also has to move freely with the eyelid and balance moisture on its faces.'"

    So you'd have your cornea removed and a new one put in? As someone who's had many eye injuries in my life, let me be the first to say "ouch".

    Actually, a cornea transplant isn't painful at all. You are asleep for the whole operation...Recovery on the other hand, while not painful to the eye, is a pain in the ass. I had to have such a transplant done due to a degenerative eye disease and I for one would love something like what this article is talking about. It would be much nicer to have the whole cornea replaced instead of just a section of it (which is what I had done, a small section about the size of my pupil was replaced.)

    I read through the whole article until I got near the end. It was only then that I realized that while the article said "cornea" I kept thinking "retina" for some unknown reason. In any case, an artificial cornea is a terrific breakthrough. People who use laser eye surgery to correct their vision can only do so a limited number of times. After that, a cornea would need to be replaced. Ideally, a replacement cornea would be able to correct vision without further adjustments.

    More interestingly, an artificial cornea can do things to improve the health of the eye. For example, an artificial cornea could be made to block UV rays or even be polarized. I'm still waiting for telescopic vision corneas but I doubt that will happen. But the idea of having built-in sunglasses is interesting to me... not that I would have it done unless it were necessary to replace my cornea anyway...

    You could polarize the eyes differently, so you don't need glasses for 3D movies anymore.

10.0 times 0.1 is hardly ever 1.0.
