IAmA: 29yr old chick, born without irises and now have one artificial iris. AMA!
I was born with a condition called Aniridia, meaning without iris. It is bilateral, occurring in both eyes. I am adopted so not sure if it is genetic or sporadic.
I've grown up with stellate cataracts in both eyes, in September 2011 the cataract in my right eye thickened and I could not see out that eye so was scheduled for surgery on 20/12/11. I had to have a special artificial iris (Morcher ring) made to fit my eye, this was made in Germany. I still have the cataract in my left eye and am in no rush to have the surgery repeated while I can still see out of that eye.
I have some pictures here: http://imgur.com/a/DRkgm#0 , I hope this is enough proof.
