D2D. If your poor night vision is due to a dense or mature cataract, your night vision will certainly be improved after cataract surgery.
However, if you have already been experiencing poor night vision even before the development of cataracts, then your poor night vision may be due to a problem in your retinal as opposed to the cataract. For cases of this nature, cataract surgery will NOT be able to improve your night vision.
Hope this helps!
