Cataract patients with a large difference in vision between the two eyes after surgery are usually unable to adapt on their own. Cataract patients with a large gap in vision between the two eyes after surgery need to go to the ophthalmology department of the hospital in a timely manner for examination to find out the cause, and then treat the cause of the problem, which is usually more difficult to adapt. For patients who have had cataract surgery in one eye only and still have a cataract in the other eye, it is possible to equalize the vision in both eyes after having surgery in the other eye. For patients with a large difference in vision due to inconsistency in the refractive status of the two eyes after cataract surgery, glasses can be worn to correct the difference and balance the vision of the two eyes. Patients after cataract surgery are advised to follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
