Proper use of neomycin, polymyxin b, and bacitracin

Squeeze a thin strip of ointment into this space. A 1-cm (approximately ⅓-inch) strip of ointment is usually enough, unless you have been told by your doctor to use a different amount. Let go of the eyelid and gently close the eyes. Keep the eyes closed for 1 or 2 minutes to allow the medicine to come into contact with the infection.
