Silicone band or sponge used to repair a detached retina is called what?

• A. Scleral buckle
• B. Vitrectomy
• C. Phacoemulsification
• D. Intraocular lens (IOL)

Answer: (A)

The concept here is how retinal detachment can be repaired from the outside of the eye. A silicone band or sponge placed around the sclera creates an external buckle that indents the wall of the eye toward the retina. This indentation reduces traction and supports the area of the retina around the tear, helping the retina to reattach when the tear is sealed with laser or cryopexy. The other procedures listed—vitrectomy (removing the vitreous gel), phacoemulsification (cataract removal), and implanting an intraocular lens—are different surgeries for other eye problems and do not use an external scleral buckle to repair detachment.
