P-Caine 0.5% Ophthalmic Solution 0.4Ml belongs to the class of 'ophthalmic anaesthetics', primarily used to numb the eye or eyes before surgery, after injury, and other tests or medical procedures. Ocular anaesthesia numbs the eye/eyes to facilitate pain-free surgery, and rapid recovery, and minimize the risks associated with the surgery. 

P-Caine 0.5% Ophthalmic Solution 0.4Ml contains 'Proparacaine hydrochloride,' a numbing medication that blocks the transmission of pain signals from the nerve endings of the eye to the brain. This blockage causes the loss of pain sensation, thus helping numb the area and relieving pain during a medical procedure. P-Caine 0.5% Ophthalmic Solution 0.4Ml is a rapidly acting anaesthetic that facilitates numbness within 30 seconds.

Your doctor will decide the dose and duration based on the severity of your pain and response to treatment.
