Answer

Anesthetics

Anesthetics are indicated for pain relief and for conjunctival and corneal scrapings. Local anesthetics stabilize the neuronal membrane and prevent the initiation and transmission of nerve impulses, thereby producing the local anesthetic action.

Proparacaine

Has a rapid onset of anesthesia that begins within 13-30 sec after instillation. Short duration of action (about 15-20 min). Since prolonged eye anesthesia can eliminate the patient's awareness of mechanical damage to the cornea, do not use outside of the ED. Frequent use of anesthetics may retard healing.
