Successful surgery cannot be achieved without thoughtful postoperative care. Patients should not press or squeeze their eyes after surgery to prevent the surgical incision from cracking, and should not wash their hair in the near future to let their eyes enter shampoo, which can cause eye infection. It is important to follow the doctor’s instructions to review the surgery on time, observe the changes in the operated eye and adjust the treatment plan. Order eye medication on time. The correct way to order eye drops is to wash your hands first. The patient is lying or sitting on his back. If you are ordering a suspension like D&B, first shake the bottle a few times. The patient’s eyes are glued to the top of the head. Peel the lower eyelid downward and dispense the eye drops into the eyelid. Be careful not to let the mouth of the drops bottle touch the eye or skin, causing eye contamination. Then cap the bottle and place it in a cool, ventilated place.
