...from a photography point of view, of course! I'll be talking to a cataract surgeon next month about my lens replacement options. I've always been extremely nearsighted - uncorrected, I'm really good at seeing splinters in fingers, but even glasses or contacts just barely get my distance vision good enough for a drivers license. I think that's one reason I like photography - if I get the focus good I can zoom in and see details that I'd otherwise miss
I've been told I should consider the extra expense of a multi focal corrective lens, and in theory, I'm really excited about the idea of being able to read the bedroom clock from bed, but I'm wondering if any of you who've had cataract surgery have chosen these multi focal lenses, and if so, how they've affected your photography. Do they affect your ability to focus your shots? Do the halos/rings some people report interfere with your photography? Thanks in advance for sharing your experience.

There is a 2nd type of multifocal lens called Vivity. This type does not have the circles and does not generate halos. It is also a toric lens and can correct astigmatism. I had these lenses inserted this past March and April.
Prior to the cataract surgery, I was very near sighted with a diopter of about -6 and it was getting worse each time I went in for an eye exam. Plus the cataracts were getting bad enough that driving at night was horrible the way lights looked like big blobs of light. And in fact I had stopped driving at night.
In actuality, the common multifocal lenses with the circles do give a wider range of correction than do the Vivity. But the cost is the halos that I did not want to have. And this has been the case. I have no halos whatsoever now that surgery is over.
The option I chose was this. For Vivigy lenses, think of dividing your vision into 4 regions -- distance, not as far distance, reasonably close and up close. When specifying what you want for each eye, you get 3 of the 4 regions. You can make both eyes the same, or offset on one eye, and this is what I did. My dominant eye is my left eye, so I went for distance, not as far distance, and reasonably close. And for the right eye, I chose not as far distance, reasonably close and up close.
What I find is that I do have presbyopia. We all encounter this problem as we age. Even though my right eye is supposed to allow me to see up close, it is a weak up close. Sitting at my computer, my right eye can read my two screens without a problem while the left eye is not as clear. But when I go outside, my eyes stop down and I can't tell any difference in the two eyes. Everything is clear. And I no longer need corrective lenses for driving. And driving at night is easy. Headlights and taillights are not blobs any longer and there are NO halos.
I did buy a new pair of glasses and I can see far and near with them. For far, they clean up a small amount of residual astigmatism. And for closeup, I can easily read my cell phone. But some things need extra help and I keep the drugstore cheepies around with 3.5x just in case I need to see something really small.
Additionally, I went to COSTCO with my prescription and had them provide me a pair that is for arm's length and up close, and these I really like using while at the computer. In fact, they are perfectly clear to about 5 or 6 feet, and for reading, the whole page is clear without tilting my head up or down for best focus as I do with the full range glasses.
When my first eye was done, I found my distance vision was not as sharp as it should be, and the surgeon did some calculations that determined that the lens needed to be turned a degree or two. This was done while the 2nd eye was operated on. He told me for rotation, he only needed to make a very tiny hole and to insert a tool to reach in and nudge the rotation the needed amount. The result was incredible. Close to 20:15 in that eye. Just a touch of astigmatism remaining, but not so much that it impacts the vision very much. The 2nd eye did not need that extra rotation.
My insurance + medicare covered the cost of a standard cataract surgery and I was resposible for the cost of the upgrade.
Very, very pleased with my vision now. I started wearing glasses at age 13 and now, 60 years later, I can enjoy life without glasses when I want to. And no problem using the camera without glasses. Everything is clear. Could have never done this before the surgery.
