After cataract surgery, patients should pay attention to strict eye hygiene, avoid eye contamination, no strenuous exercise or eye trauma, so as not to cause the surgical incision cracking and IOL displacement. Cataract is a common ophthalmic disease that causes painless, progressive vision loss. Surgery is required to restore vision. After cataract surgery, firstly, we should pay attention to avoid contamination of the eyes, for example, not to let the dirty water from washing hair and face into the eyes, not to touch the eyes with unclean hands, otherwise, once triggered by eye infections, it will seriously affect the recovery after surgery. Secondly, after cataract surgery, cataract patients should be careful not to perform particularly strenuous exercise, such as high jump, long jump, diving, etc., and should not allow the eyes to be traumatized, otherwise, the surgical incision site may crack, and it may cause the IOL to dislocate. After cataract surgery, it is recommended to take more rest and consult a doctor if there is any eye discomfort.
