Cataract surgery at your eye is very unusual. Were these congenital cataracts, or diabetic cataracts? Given your natural lens could still focus because you are only 30 not the typical 70's cataract patient your loss of ability to focus even with Symfony IOLs is going to be much more noticeable to you than much older people. I would suggest you use the search feature and read the many informative posts by people that have opted for the Symfony IOL. While a quality IOL I think it is NOT living up the the commercial hype that were claimed for it. Your options are to discuss with your surgeon and work through it or at some point get an independent second opinion.
