Surgery
Chalazion surgery is a simple procedure that is generally performed as a day operation, and the person does not need to remain in the hospital for further medical care. The eyelid is injected with a local anesthetic, a clamp is put on the eyelid, then the eyelid is turned over, an incision is made on the inside of the eyelid, and the chalazion is drained and scraped out with a curette. A scar on the upper lid can cause discomfort as some people feel the scar as they blink. As surgery damages healthy tissue (e.g., by scarring tissue or possibly even causing blepharitis), given other options, less invasive treatment is preferable.Chalazion removal surgery is performed under local or general anesthesia. Commonly, general anesthesia is administered in children to make sure they stay still and no injury to the eye occurs. Local anesthesia is used in adults and it is applied with a small injection into the eyelid. The discomfort of the injection is minimized with the help of an anesthetic cream, which is applied locally. The chalazion can be removed in two ways, depending on the size of cyst. Relatively small chalazia are removed through a small cut at the back of the eyelid. The surgeon lifts the eyelid to access the back of its surface and makes an incision of approximately 3mm just on top of the chalazion. The lump is then removed, and pressure is applied for a few minutes to stop any oozing of blood that may occur because of the operation.
It carries a quite small risk of central retinal artery obstruction, focal depigmentation in dark-skinned patients, and inadvertent ocular penetration. It is considered a simple and effective treatment option, one with high success rates. It may give the same results as surgical treatment (I&C). Larger, long-standing lesions are best treated surgically. Considering the surgical risks, steroid injection is believed to be a safer procedure in marginal lesions and lesions close to lacrimal punctum.One injection alone has a success rate of about 80%; if requested, a second injection can be given 1–2 weeks later. Carbon dioxide laser
Chalazion excision using a CO2 laser is also a safer procedure, with minimal bleeding and no eye patching  required. See also
