Definition

Noun: A surgical procedure in which the vitreous humor (the clear, gel-like substance that fills the center of the eye) is removed and typically replaced with a saline solution or other clear fluid. This is performed to treat various eye conditions that affect the retina and vitreous.

Usage

The word "vitrectomy" is a medical term used specifically in the context of ophthalmology (eye surgery). It refers to the procedure itself. * The surgeon performed a vitrectomy to repair the retinal detachment. * After the vitrectomy, the patient's vision gradually improved. * A vitrectomy is often necessary to remove blood from the vitreous cavity.
