Commonly used antibiotic eye ointments in clinical practice include erythromycin eye ointment, chlortetracycline eye ointment, tobramycin eye ointment, ofloxacin eye ointment, fusidic acid eye gel, lomefloxacin eye gel, etc. Eye ointment is usually used twice a day. Make sure to read the name and expiration date of the medication before using it, and wash your hands before and after using it. When using the medication, use your index finger to gently pull down the lower eyelid of the eye and gently squeeze the medication into the space between the lower eyelid and the eye, and do not touch any part of the bottle of the eye medication to avoid contaminating the eye medication or hurting the eye. After ordering the eye medication, gently press the inner corner of the eye for about five minutes and close the eye for at least ten minutes.
