After cataract surgery, patients need to pay attention to strictly maintain eye hygiene, avoid strenuous exercise, and do not subject the eyes to external impact. The corneal incision made by cataract surgery is self-closing and generally does not need to be sutured. After surgery, patients need to avoid contaminating their eyes, such as splashing dirty water into their eyes when washing their hair or face, or else there is a possibility that the dirty water may enter into the interior of the eye along the surgical incision, triggering eye infections, which may seriously affect the patient’s vision. Patients should also avoid strenuous exercise or external impact on the eye after surgery, otherwise the IOL implanted inside the eye will be easily displaced or shifted during the surgery, which will also affect the patient’s vision and visual quality. It is recommended that post-cataract surgery patients follow the doctor’s instructions, have regular checkups, and consult a doctor when discomfort occurs.
