For the longest time, treatment of eye diseases has gone a little like this:&lt;p&gt;Refractive errors? Wear some glasses, contacts, or have LASIK&lt;p&gt;Corneal diseases? Tricker because you need a donor, but corneal transplant.&lt;p&gt;Glaucoma? There&apos;s a handful surgeries for that depending on type, and a plethora of drugs.&lt;p&gt;Cataract? I&apos;ll take an interocular lens, please.&lt;p&gt;Partially detached retina? There are moderately successful surgeries to reattach it, rates of success depending a lot on the health of the retina.&lt;p&gt;Retinal diseases? Sorry, you&apos;re screwed.&lt;p&gt;My left eye was removed when I was in my teens, and the retina of my right eye is damaged fairly extensively due to retinopathy (from being born 2mo premature). It&apos;s lead to various complications over the years, as well.&lt;p&gt;My biggest fear is going blind. I nearly am, and I think I still have a little PTSD from the last round of eye problems.&lt;p&gt;Now, 576 greyscale pixels isn&apos;t much, but it&apos;s only going to improve over time.&lt;p&gt;It&apos;s really exciting to think that people in my situation, and possibly even myself someday, will not have to face the prospect of total blindness from retinal disease.</text><parent_chain></parent_chain></comment><story><title>Laser-powered bionic eye gives vision to the blind</title><url>http://www.extremetech.com/extreme/132918-the-laser-powered-bionic-eye-that-gives-576-pixel-grayscale-vision-to-the-blind</url><text></text></story>

Obviously that this gets approved is a great achievement, but there is _huge_ room for improvement.</text><parent_chain></parent_chain></comment><story><title>Laser-powered bionic eye gives vision to the blind</title><url>http://www.extremetech.com/extreme/132918-the-laser-powered-bionic-eye-that-gives-576-pixel-grayscale-vision-to-the-blind</url><text></text></story>
