Local anesthesia of the eye
Unlike other parts of the body, the eye is very easy to anesthetize locally, which is necessary for almost every eye surgery and is also performed as standard. However, for children and in other special cases, general anesthesia is recommended for this type of surgery. For simple operations, there is an anesthetic in the form of a gel or eye drops, which is applied to the eye and makes the operation possible.
This type of anesthesia is perceived by the patient as very pleasant and uncomplicated and involves hardly any risks for the patient. If deeper interventions on the eye are necessary, it may be necessary to anaesthetize the eyeball after the local anaesthesia described above. In this case, the eyeball is anaesthetized with a syringe at two points on the side of the eyeball. This type of anaesthesia with the syringe is performed either under short anaesthesia or under local anaesthesia and can be uncomfortable for the patient in some cases.
Local anesthesia on the finger
Fingers are very well suited to be anaesthetised individually. The standard procedure here is the so-called Oberst conduction anaesthesia. There are 4 nerves in the fingers, which report the sensations such as pain and temperature from the finger to the brain.
They are located in pairs on the upper and lower sides of the fingers, to the right and left of the phalanx. By injecting anaesthetics around the bone, these nerves are anaesthetized and can no longer transmit the pain to the brain and the patient can no longer feel it and interventions on the finger are possible without pain. Toes can also be anaesthetized very well by this procedure, since the nerves run around the bone here just like on the fingers.
After the injection it takes only a few minutes and the finger starts to become numb until it is finally completely numb. Before the beginning of the procedure the doctor always checks again whether all sensation has actually gone. Mobility is not affected by the anaesthetic and is still possible because many of the muscles used to move the fingers are located in the forearm and are only connected to the fingers by long tendons.
