Oxybuprocaine is primarily used as a local anesthetic in ophthalmology. It is applied to the surface of the eye to numb it before procedures such as tonometry, removal of foreign bodies, or minor surgical interventions. The anesthetic effect is rapid and short-lasting, making it suitable for quick diagnostic tests or minor treatments. Additionally, it can be used to relieve pain and discomfort caused by eye injuries or irritations. Its effectiveness and quick onset make it a valuable tool in eye care, ensuring patient comfort during various ophthalmic procedures.
