Complications of local anaesthesia for ophthalmic surgery.

Topical local anaesthetic agents frequently sting, and are occasionally associated with temporary clouding of the cornea, making surgery more difficult [38]. This clouding was most often seen with cocaine and is much less common with amethocaine or oxybuprocaine. Corneal anaesthesia necessitates protection,of the eye by ensur ing that it is closed and protected by a pad.
