Another case of listening to the "I heard it on the grapevine"...... Cataract surgery is performed literally 10s of thousands of times a day with miniscule failure rate. ALL surgeries, even minor procedures come with risk. The issue becomes first does the reward (i.e. seeing) outweigh the risk? Heck, you stand a larger chance of getting hit by a car in a parking lot than a failed cataract surgery performed by a "non-production" competent surgeon who specializes in the process. There are "cataract machine" centers and then there are surgeons who are thorough, cautious and detailed.... This is a case of ensuring YOU have done your homework in seeking a competent and reputable surgeon and surgical location. That is not done on forums like this, but by researching providers credentials, histories, ratings & reviews (though problem is most only report "issues" and never report successes). My wife has been through the process, starting eye issues unrelated to cataracts and then dealing with the cataracts. She chose a surgeon who had a fully equipped, state of the art surgical center, with a long history of outstanding outcomes who took every precaution, up to and including having her assessed by another expert who deals with eye disease and retina issues. There were several assessment and testing visits, including a pre-op visit the day before for each eye. End of story was two surgeries, two weeks apart, perfect outcome..... BUT....we did "OUR" homework....and in the process visited three surgeons and promptly dismissed one and then the other..... It takes WORK on YOUR part........as the Canadian Docs on YOuTube say at the end of every program...."YOU are incharge of YOUR own health!"...
