Topical Anesthetic Eye Drops
· Topical anesthetics are frequently used to anesthetize the cornea in injury
· The five most commonly used topical ophthalmic anesthetics are proparacaine, tetracaine, benoxinate (oxybuprocaine), lidocaine and cocaine.
· The most common complication (minor) associated with anesthetic eye drop use involves the patient complaint of pain/burning when instilled. This can last up to 30 seconds. It is least commonly associated with proparacaine use.
· The most common complication (major) associated with anesthetic eye drop use involves corneal epithelial erosions. This can be seen even after routine normal use.
o Prolonged or excessive use can lead to ulcerations and keratitis
o Patients should NEVER be given drops to take home and some advocate that the drops should not be left in the room as the urge to take the bottle home may overwhelm a patient in pain
