Cataract surgery by phacoemulsification is frequently performed under surface anaesthesia. Facial nerve, which supplies the orbicularis oculi muscle, is blocked in addition for intraocular surgeries. Topical anaesthesia is known to cause endothelial and epithelial toxicity, allergy and surface keratopathy. [citation needed]
Systemic complications include local anesthetic toxicity, brainstem anesthesia, and stimulation of the oculocardiac reflex. Most commonly, patients will report discomfort during the performance of the block, such as the sensation of the needle during insertion and/or pressure behind the eye during injection.
When the cornea dries out it may stick to the eyelid and cause an abrasion when the eye reopens. [11] Exposure keratitis. 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.

Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
Brachial plexus block is a regional anesthesia technique that is sometimes employed as an alternative or as an adjunct to general anesthesia for surgery of the upper extremity. This technique involves the injection of local anesthetic agents in close proximity to the brachial plexus , temporarily blocking the sensation and ability to move the ...
This method of surgery reduced the need for an extended hospital stay and made out-patient surgery the standard. Patients who undergo cataract surgery rarely complain of pain or discomfort during the procedure, although those who have topical anaesthesia, rather than peribulbar block anaesthesia, may experience some discomfort.

Anesthesiology, anaesthesiology or anaesthesia is the medical specialty concerned with the total perioperative care of patients before, during and after surgery. [1] It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine. [2]
Manipulation under anesthesia (MUA) or fibrosis release procedures [1] is a noninvasive procedure to treat chronic pain which has been unmanageable by other methods. MUA is designed not only to relieve pain, but also to break up excessive scar tissue.
