Our situation may be unique but I want to add a word of caution. My hubby is in the moderate stage of Alzheimers. He had cataract surgery last November. Both eyes...a few weeks apart. During the first surgery there were some issues with him hallucinating and "jerking". The doc said it was a difficult surgery because of the extent of the cataract and it took longer than ususal. For the second eye our doc used a different eye block for the surgery. That one went well. You may want to ask about options. About a month after the surgeries my hubby had a detatched retina and emergency surgery. Did the cataract surgery cause the detatched retina? No way to know. The recovery from the detatched retina surgery was brutal. We are still dealing with the aftermath. In both cases we had absolutely competent docs. That was not the issue.
