With the continuous improvement of cataract surgery techniques, more and more cataract patients are undergoing surgery and getting satisfactory results. However, there are some patients who just feel uncomfortable, dry, astringent and a little burning sensation in their eyes after the surgery. Why there is no such symptom before the operation and it appears after the operation? In fact, many people have dry eyes before surgery, but do not pay much attention to it and do not take it seriously. When the cataract surgery is done, the feeling of the eye is concerned, and the symptoms feel significantly worse. At the same time, surgery does cause some patients to develop dry eye in the short term after cataract surgery, called symptomatic dry eye, but the vast majority of patients can return to their pre-surgery condition after a period of time post-surgery, with the application of eye drops that relieve dry eye. Generally speaking, the dry eye symptoms after cataract surgery are mostly mild dry eye (no damage to the corneal conjunctiva). For patients who already had a certain degree of dry eye before the surgery, the surgery will not generally cause recurrent severe dry eye. Doctor’s tip: Patients should protect their eyes after surgery as prescribed by the doctor and follow up promptly. If you have symptoms of dry eye, go to the hospital in time.
