Chemical injury can occur if cleaning solutions such as povidone-iodine (Betadine), chlorhexidine or alcohol are inadvertently spilt into the eye, for example when the face, neck or shoulder is being prepped for surgery. [4] [1] Therefore, the anaesthetist ensures that the eyes are fully closed and remain closed throughout the procedure.
During the surgery, it has to be ensured that no carbon dioxide retention occurs. If this occurs, the choroid swells up and ocular contents may prolapse as soon as the eye is opened. The advantages of general anaesthesia is that it produces complete akinesia, controlled intraocular pressure and safe operating environment. It is the safest ...

The patient is unconscious and ready for surgery. This stage is divided into four planes: The eyes roll, then become fixed; eyelid and swallow reflexes are lost.
Anaesthesia may be placed topically as eyedrops or injected next to (peribulbar) or behind (retrobulbar) the eye [6] or sub-tenons. Local anaesthetic nerve blocking has been recommended to facilitate surgery. [2] Topical anaesthetics may be used at the same time as an intracameral lidocaine injection to reduce pain during the operation. [6]

Proper anesthesia is essential for ocular surgery. A facial nerve block may occasionally be performed to reduce lid squeezing. General anesthesia is recommended for children, traumatic eye injuries with cataract, for very apprehensive or uncooperative patients and animals. Cardiovascular monitoring is preferable in local anesthesia and is ...
