These drugs, unlike general anaesthetics, cause a loss of feeling in specific areas while keeping the patient conscious. Local anaesthetics are used for pain relief, soreness, itching, and irritation associated with disturbance of the integrity of the skin and mucous membranes (cuts, bites, wounds, rashes, allergic conditions, fungal infections, skin sores, and cracking). They are used during opthalmological procedures such as tonometry and gonioscopy, removal of foreign bodies, and minor surgical interventions.
