ii) Anaesthesia Step 1: Inform the participant that he/she may experience a transient stinging sensation. Request for the participant to direct their gaze upwards. Depress the lower eyelid and place one drop of LA in the inferior palpebral fornix. Do this for both eyes. Request for the patient to blink gently for at least 3 times. Step 2: Once the stinging subsides, request for the participant to direct their gaze downwards. Elevate the patient's upper eyelid and place a drop of LA on the bulbar conjunctiva on the most superior point possible. Do this for both eyes. Request for the patient to blink gently for at least 3 times. Step 3: Repeat step 2 once more. The participant should not be able to feel any stinging sensations of the eye at this point.
