Used during ophthalmic examinations and procedures including tonometry (eye pressure measurement), gonioscopy, corneal sensitivity testing, foreign body removal, and minor eye surgeries. Also utilized for contact lens fitting procedures.
Benoxinate is a local anesthetic that blocks sodium channels in nerve fibers, preventing the generation and transmission of nerve impulses. This temporarily inhibits sensation in the applied area without affecting consciousness.
For ophthalmic use only. Should not be used for long-term treatment as repeated use may delay corneal healing. Rarely, allergic reactions can occur, especially with repeated exposure. Patients should be advised not to rub eyes while anesthetic is active to prevent injury.
