For some people, eye pain will happen after the cataract surgery. For the reasons, I have to say that you may get eye infection or overuse your eyes after the surgery. And you should know that a cataract is a clouding of the normally clear lens of the eye, and if there are some problems on it, cataract surgery is needed. After the surgery, it will take about 3 weeks for your eyes to recover. At this period, your eyes will become sensitive and fragile. If you do not take care, it can make your eyes infected in the recovery period. Also, watching TV or computer in the first week will just make your eyes feel painful. So you need to pay more attention to these. Anyway, just be careful about your eyes.
All right, I believe that you must be upset about the suffering of cataract surgery. But from what we can see, it is natural for a cataract patient to get some subsequent problems after the surgery. And that is resulted from the remaining infections in your eyes. So you must follow the doctor's advice and get some follow-up checkup in the hospital to prevent glaucoma from happening.
