This document is a brief summary only. On the day of your surgery your anaesthetist will answer all of your questions and together you will decide on the best anaesthetic technique for you.
“Topical” anaesthesia has been suggested as a suitable anaesthetic technique for you. It is not suitable for other patients such as those who are very anxious, have breathing difficulties, can’t communicate easily or have potentially difficult surgery.
“Topical” anaesthesia has several advantages – you will be able to see from the eye immediately following the surgery, which reduces the risk of a fall compared with having a pad over the eye. There will be a transparent shield over the eye for protection. It is uncommon* to get complications such as bruising around the eye.
Topical anaesthesia avoids the rare* risks of local anaesthetic injections.
You will have a small plastic tube, an intravenous cannula, inserted into a vein in your arm so that medications can be quickly given if needed. You may receive a sedative medication which will help you relax, make the time pass quickly and limit any memory of what follows. You will be given anaesthetic drops on to the surface of the eye and the surgeon will use additional local anaesthetic inside your eye. You may have tape across your forehead to reduce the risk of head movement. Your other eye will be taped shut for protection. You will feel the surgeon touching you and you may hear the staff talking and see light and shapes.
What are the anaesthetic risks?
- Bruising where the intravenous cannula was inserted is common*
- Pain or discomfort during the surgery is common* but it is usually minor and transitory and needs no treatment.
If the pain is persistent and significant to you then you must tell the surgeon and the pain will be treated with additional local anaesthesia or sedation.
- Incomplete anaesthesia contributing to surgical complications is uncommon*.
- Problems with your heart, blood pressure or breathing resulting in a longer stay in hospital are uncommon*.
- Post-operative pain is more common than with other local anaesthetic techniques and is usually relieved by simple pain-killers such as paracetamol.
* Definitions used
- Very common (1 in 10) such as getting the flu or food poisoning this year.
- Common (1 in 100) such as winning any prize in one game of Saturday Lotto.
- Uncommon (1 in 1000) such as winning the trifecta in a 13-horse race.
- Rare (1 in 10,000) such as being struck by lightning.
- Very rare (1 in 100,000) such as dying from a snake, bee or other venomous bite or sting.
