This is usually done from underneath the eyelid to avoid a scar on the skin. If the chalazion is located directly under the eyelids outer tissue, however, an excision from above may be more advisable so as not to inflict any unnecessary damage on the lid itself. Eyelid epidermis usually mends well, without leaving any visible scar. Depending on the chalazions texture, the excision procedure varies: while fluid matter can easily be removed under minimal invasion, by merely puncturing the chalazion and exerting pressure upon the surrounding tissue, hardened matter usually necessitates a larger incision, through which it can be scraped out. Any residual matter should be metabolized in the course of the subsequent healing process, generally aided by regular appliance of dry heat. The excision of larger chalazia may result in visible hematoma around the lid, which will wear off within three or four days, whereas the swelling may persist for longer. Chalazion excision is an ambulant treatment and normally does not take longer than fifteen minutes. Nevertheless, owing to the risks of infection and severe damage to the eyelid, such procedures should only be performed by a medical professional. Chalazia may recur, and they will usually be biopsied to rule out the possibility of a tumour. Antibiotic/corticosteroid eyedrops or ointment
A limited course of topical antibiotic/corticosteroid combination eyedrops or ointment such as tobramycin/dexamethasone may be effective in treating a chalazion.
Expansive legal definitions of death, such as Spain uses, also increase the pool of eligible donors by allowing physicians to declare a patient to be dead at an earlier stage, when the organs are still in good physical condition. Allowing or forbidding payment for organs affects the availability of organs. Generally, where organs cannot be bought or sold, quality and safety are high, but supply is not adequate to the demand. Where organs can be purchased, the supply increases. Iran adopted a system of paying kidney donors in 1988 and within 11 years it became the only country in the world to clear its waiting list for transplants. Healthy humans have two kidneys, a redundancy that enables living donors (inter vivos) to give a kidney to someone who needs it. The most common transplants are to close relatives, but people have given kidneys to other friends. The rarest type of donation is the undirected donation whereby a donor gives a kidney to a stranger. Less than a few hundred of such kidney donations have been performed. In recent years, searching for altruistic donors via the internet has also become a way to find life saving organs.
