A retinal detachment occurs when the retina — the light-sensitive layer lining the back of the eye — pulls away from its normal position, threatening permanent vision loss if left untreated. Scleral buckle surgery attaches a small band of silicone or sponge material to the outer wall of the eye (the sclera). This band gently indents the eye wall inward, relieving the pulling force (traction) on the retina and helping it settle back into place.
Who typically needs this
- Recommended for many cases of rhegmatogenous retinal detachment (caused by a retinal tear or hole).
- Often preferred in younger patients with clear vitreous gel, or detachments with tears in certain locations.
- Considered when the detachment is not complicated by extensive scar tissue.
- Treated urgently — sudden flashes, new floaters, or a curtain-like shadow in vision should prompt same-day eye evaluation.
What to expect
- Performed under local or general anesthesia.
- The surgeon locates the retinal tear(s) and seals them with cryotherapy (freezing) or laser.
- A silicone band is attached around the outside of the eye to indent the wall and relieve traction on the retina.
- Fluid that has collected under the retina may be drained through a small opening.
- The band is usually left in place permanently and is not visible from outside once healed.
Recovery
- Some redness, swelling, and discomfort are normal for one to two weeks.
- Vision is blurry initially and improves gradually over weeks to a few months.
- The eye's focusing power may change slightly because of the buckle, sometimes requiring an updated glasses prescription.
- Follow-up visits are needed to confirm the retina stays attached and heals well.
Risks to know about
- The retina can fail to reattach or can re-detach, sometimes requiring further surgery.
- Double vision, infection, or bleeding can occur, and the buckle itself can rarely cause discomfort or need removal later.
- A shift toward nearsightedness (myopic shift) is common because of the buckle.
- As with any eye surgery, rare but serious risks include severe infection or permanent vision loss.
Frequently asked questions
Is retinal detachment an emergency?
Yes — sudden flashes of light, a shower of new floaters, or a shadow or curtain in your vision should be evaluated by an eye doctor immediately, ideally the same day.
Will the silicone band be visible?
No, it sits on the outer eye wall beneath the surrounding tissue and is not visible once healed.
Will my vision return to normal?
Vision often improves significantly, but how much depends on whether the macula (central retina) was affected and for how long before surgery.
Is scleral buckle the only option for retinal detachment?
No — vitrectomy, pneumatic retinopexy, or a combination may be used instead, depending on the type and location of the detachment.
