Hi
My friend in Spain has had it, around 4/5 years ago now I think. She used to wear contacts and like most of us got fed up when you then have to wear glasses for reading. An elderly friend of hers got it done first and ended up with 20/20 vision in her 70s which then prompted my friend to have it done. I'd never heard of it before but it may have been pioneered in Spain. Then our optician mentioned it to my hubby if his eyes got worse. My friend has had no problems and doesn't need any glasses at all.
My Dad who's vision was pretty bad had his cats done and lens replacement and can see so much better now, still needs glasses but not such a strong prescription.
I gather that it's less risky than laser as its a common op and you're not scraping away tissue which happens with laser. I'd be more inclined to go with lens replacement than laser.
I got fed up with having to wear contacts for distance but then couldn't read with them in, can read perfectly well without them in but then can't see distance! So tried multi focals but found it compromised distance when wearing sunglasses and at night, so now have the one short eye and one long eye! Takes a bit of getting used to and it's not totally perfect but so much easier than glasses on off or perched on nose!
hope this helps!
