Weakened immune systems (susceptibility to infections), wind, dusty air, or a polluted environment, as well as bad habits such as regular rubbing of the eyes, can play a significant role in the development of barley. If it does not heal with medication, a surgical opening is performed. Barley removal is a small ophthalmic operation that takes place on the inside of the eyelid, from the conjunctiva. Purulent sebum excretion, which cannot be emptied, is removed and, in most cases, the inflammatory granulation tissue is also excised. At the end of barley removal surgery, there is no need to suture the wound. After the procedure, a pressure bandage is placed on the eye.
