I had a cataract operation 2 days ago and the difference in vision between the new lens and the old one is enormous with colours much punchier. Blues are really blue. Any colour matching is a job for one eye only from now on.
Maybe if we existed in the Ghost In The Shell universe:I will probably need this done fairly shortly.
Is it like the Steampunk William Gibson scenario where you can order Zeiss Icon eyes?
Should we start a thread on the retina replacement lens with the best bokeh?
I'm 69 and my doctor says that when I get my lenses replaced for cataracts, he can correct most of my vision--since I have extreme astigmatism...

I have had cataract surgery in both eyes. While it was a great improvement, it is not a panacea. Astigmatism can be corrected by either surgical means or with the replacement lens. Also, your eyes continue to age and your eyesight may eventually change necessitating glasses. Most insurance covers the surgery and plain lenses, but will not cover corrective lenses. The additional cost of the lenses might be on you.I'm 69 and my doctor says that when I get my lenses replaced for cataracts, he can correct most of my vision--since I have extreme astigmatism in addition to strong myopia, it'll be nice to have vision close to normal without glasses, though I'll probably still need them, the prescription will be much lower. He says sometimes he can get 20/20, but can't guarantee it.
In BC our public medical coverage covers the surgery and basic corrective lenses.
Mild levity and irony has no place on the Internet, I see... I'll learn eventually.I will help start the thread drift...
1.Human eye DOF is somewhat shallow.
2. Best backround blur (which is NOT what 'bokeh' is defined as, especially not by Zeiss' definition!) is anywhere outside of a very NARROW cone of view [away from where the eye is focused at the moment]
Only the fact that the eye can instantly re-focus, away from a very narrow and very shallow zone of focus, as it moves about the FOV is what gives the IMPRESSION of wide and need zone of focus, contrary to #1 and #2
As for 'bokeh' I rather doubt that improves with cataract lens replaement, as both the original and the replacement are optically very simple, and the original is superior in its ability to refocus for near vs. far because of its inherent flexibility (which gets stiffer as we age). Until Zeiss is able to come up with a compound variable focus lens cataract replacement for our original lens, the spherical distortion correction is what it is, leaving bokeh unchanged.
In BC our public medical coverage covers the surgery and basic corrective lenses. Lenses designed to treat astigmatism will cost you more.
True - but for those of us who also have extended medical (private supplementary) insurance, the "insured" options are more extensive.Well that is the case with all insurance - it will make you 'whole' again, but it won't make you better.

Yes I have heard and seen similar comments from our own NHS eye surgeons so it really is a win-win situationI'm 69 and my doctor says that when I get my lenses replaced for cataracts, he can correct most of my vision--since I have extreme astigmatism in addition to strong myopia, it'll be nice to have vision close to normal without glasses, though I'll probably still need them, the prescription will be much lower.

If this is true, that could be quite unfortunate. After a while, the implant cannot be removed easily as tissue grows around the edge.There was an intraocular lens maker several years ago who manufactures lenses without a UV coating, and many patients were able to see ultraviolet radiation. Apparently a number of people found this unnerving and the lens were reformulated.
