Two ASPH lenses, at last!

[JRG]

And a real solution to the problem of viewfinders that scratch your eyeglasses.

For the past couple of weeks, I've been undergoing cataract surgery and recovery. So now, each eye is equipped with a brand-new, aspheric lens implant. Incredible!

Colors are dazzling, images have sharp edges again, and the world again has things that are brilliant blue. I watched a stormy sunset last night, just to appreciate the subtlety in the color changes. And as a bonus, I don't need glasses to use a camera any more. (Surprise! There are 28mm framelines out there in the periphery! 😀)

So if you're starting to develop cataracts, look on the bright side (😉): The surgery is easier than an oil change for your car, and the end result is awesome. And go for the aspheric lenses --- they're worth it.

Quite inconclusive, would like to see the MTF graphs for the lenses. 😀

How's the bokeh - or is there any left? 😛

Leica implants, I trust?

Seriously, I'm very happy for you. My wife had one eye done a few weeks ago, and the improvement was vast.

Cheers,

R.

Here you go... I had it done January 2008 in my right eye and could not be happier. I was suggested to do some research as to the different types and ended up so opinionated that I specified manufacturer and model number. Attached are the MTF results and I added the Leica results as a comparison.

I chose the Tecnis Z9000 monofocal. The Acrysof SN60WF offered a better MTF but it had a slight yellow tint to filter blue - and I didnt want the colour cast.

Mine are Tecnis monofocals, too. But an aspheric model approved (here in the US) in January 2009.

Mine is aspherical as well... I will need the left one done within the next few years and am actually looking forward to it. The vision improvement is amazing. My right was so bad I could not focus the rangefinder - had 4 focus patches and could never work out which ones to align :bang:

Apart from the horror stories I read about people trying to get their brain to adjust to the multifocals and doctors pushing the higher margin products with their kickbacks, the fact they also had only half the MTF values of the monofocals was the no brainer for me.

It actually took a lot of searching to find those MTF charts then I had to stretch them to align the scales...

WOW. My eyes are maybe nonaspherical, but I am happy with them.

When it comes time, I'm insisting on Zeiss. Sonnars to be specific! 😉

Am I reading it right?
I feel like I am stepping into the future talking with a new human generation and cyborgs.
Is there a surgery that can make me smarter?

"My eyes are maybe nonaspherical, "

Actually, they get more aspheric as you age, which is why aspheric IOLs are a good idea.

 

[JRG]

"My right was so bad I could not focus the rangefinder "

Yeah, that was one of things that pushed me into surgery. I couldn't see the focus patch in my M4, and I know that's it crisp and bright.

I'd just get an O-ring instead.

Sorry, but I prefer my natural eyes as they are. In particular the idea of fixfocus eyes sucks.

 

[ampguy]

well you have 2 of them

well you have 2 of them

the left can be optimized for close, the R for far. This is what tennis players do.

Glad u like the result. Did you pay extra for the Superman's vision?

Edit: Sorry just couldn't resist. 😉

 

[agreenspan]

Do you have to wear UV/IR filter glasses?

 

[JRG]

"Sorry, but I prefer my natural eyes as they are"

Yeah, I'd have said that at your age. But they won't stay as "they are", most likely. And when there's no more blue, and you can't even see the focus patch (along with lots of other things), fixed focus starts to seem a downright trivial concern. Besides, there are multifocal IOLs and by the time you're ready, they'll be a better choice than they are at the moment.

"Do you have to wear UV/IR filter glasses?"

Nope. UV filtering is built in. Sunglasses are good for glare and heightened sensitivity to light, though.

I'm going in the opposite direction, my sight is getting better as I get older, last eye test 20/20 in my right (camera) eye, not far off that in my left eye. Had worn glasses for 20 years. I had my eyes tested recently again for a driving license renewal (no spectacles requirement on my license now 😀) and they told me an ophthalmologist was doing research into this and the numbers were very low, like about 5 in 1000 show improving sight. I just hope it doesn't reverse...

 

[JRG]

"my sight is getting better as I get older"

Congrats! But, you can still develop cataracts even though you're 20/20. In fact, they're nearly inevitable, if you live long enough. But make the most of your current excellent sight! 🙂

What if your eye sight "keeps on getting better" as you age, and then you switch from having had short sightness to far sightness. Then, the story continues, and your eye sight bounces back to being short sighted, but one the way, you go through the point of perfect eye sight again?

short sighted--------------20/20-------------far sighted---------20/20--------?
