Anaesthesia for Cataract Surgery: Changes, Considerations and Current practice
The primary goals of anaesthesia for cataract surgery are to provide adequate analgesia, minimise patient anxiety and movement, and facilitate rapid postoperative recovery. Although general anaesthesia was historically the standard approach, it is now rarely used and is reserved for selected patients, including children, individuals with cognitive impairment, severe anxiety or claustrophobia and those with significant head tremor. Advances in phacoemulsification, foldable intraocular lenses and microincision techniques have driven a shift towards regional and topical anaesthetic approaches. Consequently, most cataract procedures are now performed as day-case surgeries under local anaesthesia.
