What Is the Success Rate of Scleral Buckling for Retinal Detachments?

Scleral buckling is a traditional yet highly effective surgical procedure used to repair a rhegmatogenous retinal detachment. Unlike a vitrectomy, which works from the inside of the eye, a scleral buckle is an "exoplant" procedure. The surgeon sutures a silicone band or sponge around the outside of the eye (the sclera). This band creates an inward indentation, or "buckle," which pushes the wall of the eye back into contact with the detached retina. This closes the retinal tear and allows the underlying fluid to be absorbed, re-establishing the critical connection between the retina and its blood supply.

Primary Reattachment Success Rates

Clinical data from 2026 indicates that the primary success rate for scleral buckling is between 85 percent and 90 percent. This rate is highest in "uncomplicated" detachments where the macula is still attached (Mac-On) and there is no significant proliferative vitreoretinopathy (PVR), which is internal scarring. If the first surgery does not result in full reattachment, a second procedure (often a vitrectomy) can bring the final "ultimate" reattachment rate to over 95 percent.

Long-Term Visual Outcomes

While the anatomical success of reattaching the retina is very high, visual success depends heavily on the timing of the surgery. If the macula (the center of vision) was detached before the buckle was placed, the final visual acuity may be limited even if the retina is perfectly flat. In 2026, studies show that 60 percent of "Mac-Off" patients achieve 20/40 vision or better after healing, whereas nearly 90 percent of "Mac-On" patients maintain their pre-detachment vision levels. Because the buckle stays on the eye permanently, these results are generally very stable over the long term.

Scleral Buckling vs. Vitrectomy in 2026

In the modern surgical environment, scleral buckling is often preferred for younger patients (under age 50). This is because buckling does not cause the rapid development of cataracts, which is a near-certain side effect of vitrectomy surgery. Additionally, buckling is highly effective for "inferior" detachments (at the bottom of the eye), where gas bubbles used in other surgeries may not provide enough pressure. Many 2026 surgeons also utilize a "combined" approach for complex cases to maximize the chances of a one-stop success.

Risks and Potential Complications

Because the buckle changes the physical shape of the eye, the most common "side effect" is a change in the eye's refractive error. Most patients become more nearsighted (myopic) by 1 to 2 diopters after the procedure because the buckle slightly elongates the eye. Other risks in 2026 include "buckle extrusion" (where the band works its way through the tissue years later) or infection of the silicone material, though these occur in less than 1 percent of cases. Double vision (strabismus) can also occur if the buckle interferes with the movement of the extraocular muscles.

FAQs on Scleral Buckling Success

Can the buckle be felt or seen?

No. The buckle is placed deep behind the eyelids and is covered by the conjunctiva (the clear skin of the eye). It is not visible to the naked eye, and because it is sutured to the sclera, you cannot feel it moving when you blink or look around.

Does a scleral buckle ever need to be removed?

In the vast majority of cases, the buckle remains on the eye for life. It is only removed if it becomes infected or if it begins to erode through the surface of the eye. Removing a buckle after the retina has healed does not usually cause the retina to detach again, but it is avoided unless medically necessary.

Is the recovery easier than a vitrectomy?

The "positioning" recovery is often easier because you usually do not have to maintain a face down posture. However, the external part of the eye is often more sore and swollen for the first 2 weeks compared to a vitrectomy, as the surgeon has to work with the muscles on the outside of the globe.

When to Discuss a Scleral Buckle with Your Surgeon

If you are a young patient with a "fresh" retinal detachment, you should specifically ask your surgeon if you are a candidate for a scleral buckle rather than a vitrectomy. Preserving your natural lens and avoiding a cataract is a significant advantage in 2026. While the surgery requires a high level of technical skill, its 90 percent success rate and long term stability make it a "gold standard" for retinal repair that has stood the test of time.
