I had Cataract surgury over 4 weeks ago, After surgury my eyesight was super great in fact i have never ever been able to see that well, Now I have a white cloud when I try to read anything and have to use bifocales, I have been back to her 3 times and she keeps giving me more drops, She also said that I might need laser surgury in 6 months . My eyesight is getting worse every day.What could it be as she gives me no answers
