Local anaesthetics

Local anaesthetics for the eye

There are various reasons to use local anaesthetics in the eye:

  • pain caused by a corpus alienum and its surgical removal
  • other eye surgery
  • to facilitate diagnostic research, e.g. for measurement of eye pressure

Oxybuprocaine and  tetracaine have a short duration of action.

For the precise mechanism of action see the pain section.
