But now I see

They use an acrylic plastic which is very very very cheap but turns yellow over time after exposure to UV. I make better optical polymers than that at work, as do many other people, and I can't figure out why they're not using them. Inertia? The opthamologist was surprised to hear that nearly all organic materials turn yellow under UV and that alternatives were available, but not used by the prosthesis makers. Weird.

Well there's a business opportunity for you, then. Here's a list of all the IOL manufacturers, each linked to their product specs. Sell them on some new polymers and, given the volume of cataract surgery, you could be rich beyond your dreams.

No market. The polymers they're using now are dirt cheap and their customers don't know the difference.

And I make more money than I need, or want.

Currently I'm making a material (actually 3 materials) to make better photovoltaic devices. It's cheap to make (yay!) and provides a very large financial benefit to our customers (yay!). I have a great high-transmittance optical material with a high refractive index which is a little pricey but is very rubust to x-rays and gamma rays (UV does nothing to it) but other than optics for satellites (too small a market to care about) its not worth anything... yet.

I had my 2nd cataract surgery 2 years and 4 months ago. By coincidence, I am having a laser procedure done on that eye today. There is a common problem following cataract surgery where the back of the capsule which holds the lens becomes cloudy from cells 'sticking' to it. I don't know the details of the mechanism but its probably due to the prosthesis* 20-30% of cases.

Yes I have some concerns about that. Sorry the laser thing didn't work out on the scheduled day. I hope the next go round will be more positive

Thanks for the good thoughts.

Could be worse ... but I still hate the fuzziness in the left eye (although it tests 20/20 which is really odd).

Shoot, I stare at high intensity UV all day [literally] ...and no knife is gettin' near my retinas! ....any time time soon, maybe my sixties...

Hmmm. Here I am just three weeks after the left eye op and it too tests 20/20 - sharp and colourful vision. But there's a haziness (not much like a floater) that drifts into place after a few moments and yes, things get a bit fuzzy and then a minute or two later sharp again. Obviously not a problem of the age of the new lens. It's kind of Hollywood soft focus. We live in hope

Ah! Just got the title;

"Amazing Grace, how sweet the sound,
That saved a wretch like me....
I once was lost but now am found,
Was blind, but now, I see.

Just had round two of laser surgery. Much better this time. We'll see how it turns out in a day or three.

Pretty good. As well as can be expected actually. Les inflammation than the first time too.

Best wishes for a good result and a speedy recovery, rubato.

[kristina]

That is good news, rubato.

And writing as someone who is almost certain to develop cataracts, I find your experience with the process lessens the fear I have of letting anyone anywhere near my eyeballs...

I am pleased it went well Rubato. Here is hoping for a great recovery.

[Beer Sponge]

Good luck with the recovery rubato!

Yeah, I'm with you, there is a high 'creep factor' there. Put it off as long as you can. But when it gets bad enough that you need it, you'll do it. It's really not that bad. Between my first > 14 years ago and the second eye 2.5 years ago, it improved significantly.

Thanks for the good wishes to all, it worked pretty well. Inflammation is gone and my vision is MUCH better now. YAY! An odd thing is that the left eye still tested 20/20 even though vision was very blurry. I'm not at all impressed with the sensitivity of the measurement.

Belatedly reading this - I'm glad it went well

Me too!

Removed my comment, which was aimed at Meade, (who would have seen the joke,) but could have been construed as being aimed at rubato, (who would not have.)

Plus it was questionably humorous in any case, so a win all round!

[Gob]

My humour questionable? Never !

Your truly determined and hate-filled poster can remove the comment while leaving the insult intact!


Troll-troll-troll your boat.

So you mean although I would have seen, now I don't get to see? I see.

rubato, I get your point but also look at it another way. I may have understood something in reference to me as amusing (perhaps owing to some prior comms between Gob and myself; perhaps realising it was aimed at me). But that same statement, if applied to some other person, might be taken seriously and cause offense.

On a simplistic level, where I'm comfortable, if Gob said "You're a pratt" and it was clearly said to me - I'd assume it in the friendly, pissed-in-a-bar, punch in the shoulder kind of way. But if you thought that Gob was saying that you are a pratt, I think you would be offended and probably rightly so. See? I wouldn't be offended if Meade and rubato names were swopped in the above quote - I'd just assume Gob had reason to think that his deleted statement would not have been seen by me as a joke if I thought it was aimed at me.

Well that's all right then

Cheers
Meade
