Limit topical anesthetics to single use for initial symptom relief and to aid exam
Repeated use of topical anesthetics may be toxic to the corneal epithelium and may impair healing (e.g., risks corneal melting, ring infiltrates, and infection).[13][15][16]
Topical anesthetics can provide initial symptom relief and aid exam in patients with corneal abrasions or recurrent corneal erosions, but should be limited to single use by a medical professional.[13][15][16]
Patients should not receive topical anesthetics for use at home.[15]
