What is vitrectomy?

Vitrectomy is defined as the surgical procedure involving the removal of the vitreous humor, which is the clear gel-like substance that fills the space between the lens and the retina of the eye. This procedure is often performed to treat various eye conditions, such as vitreous hemorrhage, retinal detachment, or advanced diabetic retinopathy. By removing the vitreous humor, surgeons can gain access to the retina, allowing them to repair any damage or perform additional procedures that may be necessary for the patient's vision.

While repair of a detached retina is a possible outcome following vitrectomy, the primary definition of the procedure itself is the removal of the vitreous humor. Other choices present methods related to eye treatment but do not accurately define vitrectomy. For example, transplantation of eye tissue refers to a completely different process involving the replacement of damaged tissues, and laser treatment for retinal disorders is a separate intervention that might be done in conjunction with vitrectomy but is not part of the vitrectomy procedure itself.
