Eye ointment stays in the eye for a longer period of time, allowing the drug to be absorbed more fully, reducing the friction of the eyelid on the cornea, and preventing lid adhesions from occurring. Because eye ointment is viscous, it is often applied before bedtime so that it does not interfere with daily life and work. How to operate: With one hand, gently pull down the lower eyelid to fully expose the lower conjunctival sac, and with the other hand, squeeze a small amount of eye ointment into the conjunctival sac; if a glass rod is available, squeeze the eye ointment onto one end of the rod, parallel to the lid fissure, and place the rod in the conjunctival sac from the side, then close the eyelid and pull the rod out from the outside, taking care not to injure the cornea. Caution: 1. Squeeze out a little eye ointment before use and discard it, then squeeze out the eye ointment and apply it to the conjunctival sac. 2, each application of eye ointment only the size of a green bean can be used, without too much.
