When a child has an infectious disease such as conjunctivitis or keratitis, eye drops are needed to treat it. When the medicine is put into the eye, it acts directly on the localized lesion and has a therapeutic effect. However, because the eyes are constantly blinking, the eye space is very small, and children often cry when using medication, so the eye medicine can only stay in the eye for a short period of time, so the eye drops should be dripped diligently in order to ensure that the medicine can really play its therapeutic role. Eye medicines are divided into eye drops and eye ointment. Eye drops are aqueous, drops into the eye does not affect vision, so it is suitable for daytime drops. Eye ointment is a paste, on the after vision, children generally can not accept, easy to rub the eyes, affecting the efficacy of the eye ointment is generally applied before bedtime. Parents are advised to seek the child’s cooperation before applying the eye drops. Cooperative children can be placed in the sitting or supine position with their faces facing upwards. An uncooperative child can be placed in a sitting or supine position, face up. An uncooperative child can be held by a parent who holds the child’s torso and hands, while the parent’s legs are held between the child’s legs and the other parent immobilizes the child’s head, face up. Before administering the drops, parents must check the name of the medicine on the bottle and check it before administering the medicine. When dropping the medicine, the parent’s left hand fingers downward peel down the eyelid, after exposure of the right hand holding the bottle of medicine aimed at the eye 1-2 drops, and then continue to peel down the eye for a few seconds, so that the medicine stays in the eye, and then let go of the child to let the eyes closed, which ensures that the medicine stays in the eye for a while longer. After the eye drops, the medicine sometimes flows down the nasolacrimal duct into the pharynx, and the child may feel a bitter taste in the mouth. Water can be used to rinse the mouth to remove any residual medicine in the mouth. If possible it is best to press on the tear duct area of the tear point for 2-3 minutes after the eye drops are put in. When applying eye ointment, the child should also be positioned face up, with the lower eyelid peeled back to squeeze the ointment into the eye, or with a small, clean, smooth glass rod dipped in eye ointment.
