The first recorded use of local anaesthesia for surgery was the instillation of cocaine into the conjunctival sac in 1884 by an Austrian ophthalmologist, Karl Koller (18581944), at the suggestion of Sigmund Freud. In the UK, during the past 10 yr, a major change in anaesthetic practice has taken place and the majority of ophthalmic surgical patients now undergo regional rather than general anaesthesia. This change has been driven in part by the pressure to undertake surgical procedures as day cases. It is important to remember, however, that there are specific risks associated with local anaesthesia for intraocular surgery and that serious complications of general anaesthesia have always been uncommon in ophthalmology, despite the advanced age and poor state of health of many patients in this group.
