Well, generally speaking, after the surgery, it is possible to have halos in your eyes. And in common, there are two factors which can lead to this situation. First, if the corneal flap does not adhere properly after surgery, the halos can occur. Also, if the pupil is dilating to a size larger than the treatment zone, it can lead to halos too. But you should know that for most people, it will last more than 30 days to recover. And you also need to go and see the eye doctor, so that he can give some medical care. Also, after the surgery, you should pay more attention to your eyes, or it can be infected easily.
After cataract surgery, your eye may feel sensitive, for several days, you may even see a glare of halos. While, do not worry, it will disappear after several days. You can go back to work and do normal daily activities except for driving, and avoid lifting heavy stuff, which can increase intraocular pressure.
