👉 Brontoscopy is a surgical procedure that involves removing the skin and fat from the eyelids to improve vision. It is used to treat various conditions, including glaucoma, retinopathy of prematurity, and cataracts. The surgeon makes small incisions in the lid and then removes the skin and fat using tools such as an instrument called a brontoscope. This procedure can be performed under general anesthesia or with local anesthesia provided by a doctor.
