My husband has LBD with mild Parkinsons at the age of 68. He had both cataracts replaced 2 weeks apart with no problems, but it was three years ago when the LBD was very mild. My only problem is with the 4 - 6 month wait.....things can change a lot in that amount of time with Dementia related diseases. If this was us, I would be pushing for a much faster time frame or even ask for referrals to other equally competent, understanding ophthalmologists. We got in the next week and two weeks later for his cataract surgeries. Good luck!
