Adults:
For short ophthalmic procedures, use a 0.4% solution. Instil 1 drop into the conjunctival sac, and tonometry can be performed after 60 seconds. A further drop, given after a 90 second interval, provides enough anaesthesia for fitting contact lenses. Giving 3 drops at 90 second intervals produces enough anaesthesia within 5 minutes to remove a foreign body from the corneal epithelium or to incise a meibomian cyst through the conjunctiva. To limit systemic absorption, press on the lacrimal sac at the medial canthus for one minute during and after instillation. Avoid use in heart block, epilepsy, impaired cardiac conduction, or myasthenia gravis, and do not apply to inflamed or infected tissue or damaged mucosa. Protect the anaesthetised eye from dust and bacterial contamination, since prolonged application can damage the cornea. Do not drive until normal vision has returned.
Side Effects
Hypersensitivity reactions; brief stinging and blurred vision; CNS excitation; muscle twitching and tremors; convulsions.
