Local anaesthesia is a way of numbing part of the body, such as the eye and surrounding tissues, so surgery can be performed while you stay awake but comfortable.
How local anaesthesia is used in eye surgery
For many cataract, glaucoma, and retinal operations, numbing drops and carefully placed injections block pain and reduce eye movement while you remain able to breathe, swallow, and communicate normally.
This approach avoids the longer recovery and risks associated with a full general anaesthetic in many patients.
- Often combined with gentle sedation so you feel relaxed and drowsy
- The anaesthetist or nurse monitors your comfort throughout the procedure
- You will hear voices and may feel pressure or touch, but not sharp pain
- Most people can go home the same day with an escort
Before and after local anaesthetic eye surgery
You will usually be asked about medications, allergies, and medical conditions beforehand so the anaesthetic plan is safe and tailored to you.
After the operation the eyelids or face may feel numb or heavy for a few hours until the anaesthetic wears off.
- A patch or shield may be placed over the eye to protect it on the journey home
- Arrange for someone to accompany you, as driving is not allowed straight afterwards
- Follow instructions on eye drops, pain relief, and when to remove any dressing
- Contact the hospital urgently if you experience increasing pain, swelling, or breathing difficulties
