Oxybuprocaine Hydrochloride is used as a ocular topical anesthesia for eye pressure measurement.

Eye Pressure Measurment

• One drop into the conjunctival sac is enough to anaesthetize the surface of the eye and allow tonometry after one minute. A further drop after 90 seconds provides adequate anaesthesia for contact lens fitting. Three drops at 90 second intervals provide enough anaesthesia to remove a foreign body from the corneal epithelium or to incise a meibomian cyst through the conjunctiva. After about an hour, corneal sensitivity returns to normal.
• Instill the recommended dosage into the eye dropwise.

Side effects are rare but the followings can appear-

• Eye irritation
• Blurred vision

Eye Irritation

Blurred vision

• Instillation may cause temporary stinging and blurring of vision.
• Dust and bacterial contamination of the anesthetised eye should be avoided.
• In normal concentrations, oxybuprocaine is less irritant than amethocaine when applied to the conjunctiva.
• Prolonged use of anesthetic eye drops may cause corneal damage.
