The halos after the cataracts surgery may caused by the intraocular lenses. I heard that halos can occur because the Intraocular lens are present all over the day and mainly during night. Anyway, you'd better see a doctor and have your eyes checked to find what really going on on your eyes. Good luck.
It is not ok for your eyes. It means that your cataract surgery doesn't treat your eyes fully. The capsule membrane turbidity after the cataract surgery may cause your situation. You'd better go to the hospital to have a full check on the eyes. Wish you be healthy at both eyes.
Well, you should know that cataract is quite a serious eye disease and it could lead to a lot of symptoms, and the halos you described is one of them. Indeed, there will be some lasting impact on your eyes after taking the surgery since it will take some time to recover. So, you don't have to worry. If you really want to know where went wrong, you might as well consult the professional doctor.
