I'm evaluating different lens implant options as I consider cataract surgery. Some lenses correct for near; others for far; and one potentially does it all (but quite expensive). My question is if I am corrected for distance, I potentially won't be able to read the settings in my viewfinder? Yes, there is a diopter adjustment on the viewfinder (Sony A1), but it changes the focus of both the subject I am shooting and also the camera settings around the sides of the image. Can someone who has had cataract surgery/implants give me some guidance on how they dealt with this? I will be seeing the eye surgeon in about a month, so I'm trying to do a lot of homework so I am prepared to have a knowledgeable discussion with the doctor. Thanks in advance for any perspectives you can share.
Mike, hello!
The one thing you lose with Cataract surgery is Accommodation, of the ability to focus near and far. However, if you’ve been using glasses at all, you already were living with some compromise in that realm.
Getting to the point — as a photographer, go for the infinity-focus lens.
PROs: You will have everything from just beyond arm’s length to infinity in focus! It’s like having f/32 without defraction!
CONs: You need reading glasses - possibly two for computer distance and nearer work like reading or using your phone. A bifocal works well.
WHY NOT y or z?
Intermediate/near focus lenses will require you to wear glasses for seeing far and maybe even for driving. As a photographer, this will handicap you in the field.
Multi-focal lenses use concentric areas of varying focal length, so based on your pupil size, you can see distance or near. Seems like the “holy grail” but it has a significant number of folks complaining of light halos and chromatic aberrations. NOT what a shutterbug wants!
cataract surgery (with infinity lenses) literally gave me a new lease of life. I should also add that after surgery, there is a significant color shift, specially in the blue range, because cataracts impart a muddy yellow tinge to vision. I was astounded by how blues suddenly seemed so vibrant. It’s akin to an old painting after restoration
In terms of camera usage, I need readers to use my LCD, but through the viewfinder, it’s much like a bloke with no vision issues — clear as crystal. I have set my viewfinder to include most, if not all the info I need to set up a shot.
Hope this helps, and good luck with your surgeries.
