What Is Scleral Buckle Surgery?
Scleral buckle surgery is an operation to repair a retinal detachment — a condition where the retina separates from the back wall of the eye. Your surgeon places a small silicone band or sponge on the outside of the eye, pushing the eye wall inward to support the retina while a freezing treatment (cryotherapy) seals the tear.
Unlike vitrectomy, which operates inside the eye, scleral buckle works entirely from the outside. The silicone element stays in place permanently — invisible, painless once healed, and providing lasting support.
The question on your mind: is a permanent implant safe? Yes. The buckle becomes incorporated into your eye’s tissue over time. Fewer than 5% of patients ever need it removed.
What Conditions Does Scleral Buckle Treat?
- Rhegmatogenous Retinal Detachment — Repairs detachments caused by a retinal tear, particularly in younger patients or those with tears in the lower portion of the eye.
- Retinal Dialysis — A tear at the edge of the retina, often caused by eye trauma. Scleral buckle’s permanent support makes it the preferred repair for this condition.
In complex cases — such as those with scar tissue on the retina or very large tears — scleral buckle may be combined with vitrectomy.
How Scleral Buckle Surgery Works
The procedure has three key steps:
First, the tear is sealed. A cryotherapy probe (freezing) is applied to the outside of the eye over the retinal tear. The freezing bonds the retina to the tissue beneath it, forming a permanent seal over 1–2 weeks.
Second, the buckle is placed. A silicone sponge or band is sutured to the sclera (the white wall of the eye) over the tear. The buckle indents the eye wall inward, relieving traction on the retina and allowing it to settle back into place.
Third, fluid may be drained. If fluid has collected beneath the detached retina, your surgeon may drain it to help the retina reattach more quickly.
One long-term effect to know about: The buckle slightly changes your eye’s shape, causing a permanent shift toward nearsightedness (typically 1–2 diopters). You will need updated glasses once healed.
What to Expect
Before Your Surgery
Retinal detachment is urgent. Surgery is typically scheduled within 24–72 hours of diagnosis — sooner if the macula (central retina) is still attached.
- Nothing to eat or drink for 6–8 hours before surgery
- Arrange a driver — you cannot drive home after surgery
- Plan for 4–6 hours total at the surgical facility (prep, surgery, and recovery)
- Expect 1–2 weeks off work for desk jobs; 3–4 weeks for physical labor
During the Surgery
Scleral buckle surgery is not painful. Your eye is completely numbed with local anesthesia, and you’ll receive IV sedation to stay comfortable. Most patients are awake but drowsy — you may feel mild pressure, a cold sensation from the cryotherapy, and gentle tugging, but not pain. The surgery takes 1–2 hours.
After Your Surgery
The first 1–2 weeks are the hardest part of recovery. Expect moderate pain and significant swelling — scleral buckle causes more discomfort than vitrectomy because the surgeon repositions the muscles that control eye movement. Pain improves daily with prescribed medications.
What’s normal: Eyelid swelling (peaks at 48 hours, resolves in 1–2 weeks), a red patch on the white of the eye (harmless), temporary double vision, and blurry vision that improves over weeks.
Unlike vitrectomy with a gas bubble, scleral buckle alone typically does not require strict head positioning. You can sleep and move normally.
When to call us immediately at (310) 269-8565:
- Severe pain that worsens instead of improving
- A shadow or curtain returning in your vision
- Sudden decrease in vision
- Redness with discharge, fever, or pain out of proportion to expected recovery
Follow-up schedule: Day 1, Week 1, Week 2, Week 4, and Weeks 8–12. Your new glasses prescription is typically obtained around week 8–12.
Risks and Side Effects
Your retina specialist will discuss the specific risks relevant to your case.
Common side effects (expected):
- Pain and soreness — moderate for 1–2 weeks; managed with prescribed medication
- Swelling and red eye — peaks at 48 hours; resolves over 1–4 weeks
- Temporary double vision — affects roughly one-third of patients; usually resolves within 2–4 weeks
- Myopic shift (increased nearsightedness) — permanent; corrected with updated glasses
Rare but serious risks:
- Re-detachment requiring additional surgery — 5–15% of cases; with reoperation, overall success exceeds 90%
- Persistent double vision (strabismus) — about 3% of patients need corrective surgery
- Buckle erosion or infection — very rare (less than 2%); may require buckle removal
- Scar tissue on the retina (PVR) — 5–10% of cases; may require vitrectomy
- Intraocular infection — extremely rare (less than 0.05%); requires emergency treatment
Perspective on risk: The risks of surgery are low compared to the near-certain vision loss from an untreated retinal detachment.
Results and Recovery
Scleral buckle is one of the most successful retinal surgeries. In appropriate cases, the retina reattaches after a single surgery 85–90% of the time. With reoperation if needed, the overall success rate reaches 92–98%.
Visual outcomes depend on timing. If the macula was still attached at surgery, 85–95% of patients achieve driving-level vision (20/40 or better). If the macula was already detached, outcomes are more variable — every additional day reduces the chance of full recovery.
Why scleral buckle for certain patients: It preserves the natural lens — avoiding vitrectomy’s higher cataract risk (30–50% over 10 years vs. 5–15% with buckle). This matters most for younger patients.
Recovery timeline:
- Week 1: Pain improving; vision very blurry; rest and limited activity
- Weeks 2–3: Pain minimal; swelling resolving; light activity and desk work possible
- Weeks 4–6: Vision noticeably better; most restrictions lifted; return to exercise and driving
- Weeks 8–12: Vision approaching final level; new glasses prescription obtained
- Months 3–6: Final vision stable; complete normal lifestyle
