What is Opthaine used for?

Opthaine is primarily used as a local anesthetic for the eye. Its active ingredient, proparacaine hydrochloride, works by blocking nerve signals in the cornea, which allows for temporary loss of sensation in the eye. This property is crucial during various procedures, such as tonometry (measuring intraocular pressure) or foreign body removal, where a sensation-free eye can enhance comfort and facilitate the examination or treatment. While other options mention treatments for infections, inflammation, or tear production, Opthaine specifically targets the local anesthesia aspect, making it an essential tool for veterinary ophthalmic procedures.
