Some individuals have thicker Meibomian gland secretions than others and, therefore, have a greater risk of developing a chalazion. If you have had one chalazion, you are at greater risk of developing another one in the future. People with acne rosacea , because of alterations within the oil glands of the face, are at greater risk of developing chalazia. The regular use of warm compresses applied to the closed eyelids for five minutes before bedtime can be helpful in preventing the Meibomian glands from clogging during the night. In people with seborrhea of the lids and recurrent chalazia, warm compresses and careful cleansing of the lid margins can be helpful for prevention. Some patients with recurrent chalazia can benefit by chronic use of oral low-dose tetracycline , which changes the metabolism of the oil-producing glands.
Sometimes, as a last resort, surgery is performed. 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 patients feel the scar as they blink. Of course, as surgeries are intrusive and damage healthy tissue (., leaving behind scar tissue or possibly even causing blepharitis ), given other options, less intrusive treatment is always preferable. Similarly, chalazia may recur once the eye is predisposed and surgical intervention each time is not possible. So surgery should be considered only as a last resort, performed on as few as 5% of all chalazia patients.
