6.2 PREPARING THE PATIENT
• Use an appropriate topical anaesthetic to
numb the cornea.
• Place a strip of fluorescein-soaked paper near the outer canthus in the lower conjunctival
sac. After a few seconds, the lacrimal fluid will be coloured and the paper may be removed.
When using drops, we recommend a 0.5% solution of fluorescein sodium. If using a 1% or
2% solution, use a glass rod to introduce a small quantity of liquid into the conjunctival sac.
