Scleral Buckling Surgery Without Vitrectomy — Cost, Top Hospitals & Success Rates | MyMedicPlus

Scleral buckling surgery is a well-established ophthalmic surgical technique for repairing rhegmatogenous retinal detachment (RRD) — a condition where the neurosensory retina separates from the underlying retinal pigment epithelium through one or more retinal breaks. First developed in the 1950s by Dr. Charles Schepens, scleral buckling has been a cornerstone of retinal detachment repair for over seven decades and remains a highly effective procedure, particularly when performed without concurrent vitrectomy.

Rhegmatogenous retinal detachment affects approximately 1 in 10,000 people annually, with a lifetime risk of about 1 in 300. Risk factors include high myopia (nearsightedness), prior cataract surgery, ocular trauma, lattice degeneration, and a family history of retinal detachment. Without treatment, retinal detachment progresses to involve the entire retina, leading to permanent vision loss. Retinal detachment is therefore considered an ophthalmologic emergency requiring prompt surgical intervention.

The principle of scleral buckling is elegantly simple: a silicone band or sponge is sutured to the outer surface of the eye (the sclera), creating an indentation (buckle) that pushes the scleral wall inward toward the detached retina. This reduces vitreous traction on the retinal break, brings the retinal pigment epithelium into contact with the detached retina, and allows the subretinal fluid to absorb. Combined with cryotherapy or laser retinopexy to seal the retinal break, scleral buckling achieves retinal reattachment in 80% to 90% of uncomplicated cases without the need to enter the eye (vitrectomy), preserving the natural vitreous gel and avoiding vitrectomy-related complications.

Scleral buckling without vitrectomy is primarily used for specific types and presentations of retinal detachment where the technique offers distinct advantages over vitrectomy-based approaches.

• Uncomplicated rhegmatogenous retinal detachment — retinal detachment caused by one or more identifiable retinal breaks, without significant vitreous hemorrhage or proliferative vitreoretinopathy
• Retinal detachment in young and phakic patients — patients with a clear natural lens (no cataract), where vitrectomy would accelerate cataract formation
• Inferior retinal detachments — detachments in the lower portion of the retina where gas tamponade positioning after vitrectomy would be impractical
• Retinal detachment with dialysis — large peripheral retinal tears (dialyses), often from trauma, that respond well to scleral buckling
• Retinal detachment in myopic eyes — high myopia with peripheral retinal breaks amenable to external support
• Pediatric retinal detachment — children and adolescents who may not comply with post-vitrectomy positioning requirements
• Recurrent retinal detachment — as a supplemental procedure to support a previously repaired retina when new peripheral breaks develop

The ideal candidate for scleral buckling without vitrectomy is a patient with a relatively uncomplicated rhegmatogenous retinal detachment where all retinal breaks can be identified and localized, the vitreous is clear (no significant hemorrhage obscuring visualization), and there is no advanced proliferative vitreoretinopathy (PVR grade C or higher). Young, phakic (non-pseudophakic) patients are particularly good candidates because vitrectomy in this population accelerates cataract development, often requiring additional surgery within 1 to 2 years.

Scleral buckling is also preferred for patients who cannot comply with the strict face-down or lateral positioning required after vitrectomy with gas tamponade, including very young children, elderly patients with orthopedic limitations, and patients with cognitive impairments. Patients whose work or travel plans preclude the flight restrictions associated with intraocular gas are similarly well-suited to scleral buckling. The procedure is also appropriate for patients with inferior retinal detachments, where gas tamponade is biomechanically ineffective.

Contraindications to scleral buckling without vitrectomy include dense vitreous hemorrhage preventing visualization of retinal breaks, advanced PVR with fixed retinal folds, posterior retinal breaks near the optic nerve or macula that cannot be supported by an external buckle, and cases where all retinal breaks cannot be definitively identified. Prior scleral surgery, strabismus surgery with extensive scleral scarring, or thin sclera (e.g., in patients with high myopia or scleral ectasia) may increase surgical complexity. In these situations, vitrectomy — either alone or combined with scleral buckling — is the preferred approach.

The scleral buckling procedure begins with a 360-degree conjunctival peritomy (opening the conjunctiva around the cornea) to expose the sclera and the four rectus muscles. The retinal breaks are localized using indirect ophthalmoscopy with scleral depression, and their positions are marked on the sclera. Cryotherapy is then applied to the sclera overlying each retinal break, creating an adhesive inflammatory reaction that will permanently seal the break once the retina reattaches.

A silicone sponge (segmental buckle) or solid silicone band (encircling buckle) is then sutured to the scleral surface to create the buckling effect. A segmental buckle is used when retinal breaks are limited to one or two quadrants, while an encircling band (360-degree circumferential buckle) is preferred when breaks are widespread, in cases with significant lattice degeneration, or when there is a higher risk of developing new breaks. The height and position of the buckle are carefully adjusted under indirect ophthalmoscopic visualization to ensure the retinal break sits precisely on the buckle crest.

Subretinal fluid drainage may or may not be performed depending on the surgeon's preference and the volume of subretinal fluid. Non-drainage techniques are associated with lower complication rates but may result in slower visual recovery. When drainage is performed, a small scleral incision is made to release subretinal fluid, facilitating immediate retinal reattachment. Intravitreal air or gas injection may be added to provide temporary internal tamponade, especially when the retinal break is located superiorly.

An important variation is the chandelier-assisted scleral buckle, which uses an internal fiber-optic light source to improve visualization during buckle placement, particularly in pseudophakic eyes where indirect ophthalmoscopic view may be suboptimal. Modern advances also include laser retinopexy as an alternative to cryotherapy for sealing retinal breaks, offering more precise treatment with potentially less inflammatory response.

Scleral buckling without vitrectomy offers several distinct advantages over vitrectomy-based approaches for appropriate candidates. The most significant benefit is preservation of the natural vitreous body, which maintains the eye's natural optical properties and protects the crystalline lens from accelerated cataract formation. In phakic patients, vitrectomy leads to cataract development within 1 to 2 years in approximately 80% of cases, often requiring additional surgery. Scleral buckling avoids this cascade entirely.

The procedure achieves primary anatomical success (retinal reattachment) in 80% to 90% of uncomplicated cases, with final anatomical success rates exceeding 95% when re-operations are included. The SPR (Scleral Buckling vs. Primary Vitrectomy in Rhegmatogenous Retinal Detachment) multicenter study demonstrated equivalent anatomical and functional outcomes between scleral buckling and vitrectomy for uncomplicated phakic retinal detachments, with fewer secondary procedures needed in the scleral buckling group.

Additional benefits include the absence of intraocular gas, meaning patients have no altitude or air travel restrictions post-operatively and do not need to maintain specific head positioning. The external approach preserves intraocular structures and carries a lower risk of iatrogenic retinal tears compared to vitrectomy. Long-term visual outcomes are favorable, particularly when the macula remains attached at the time of surgery — visual acuity of 20/40 or better is achieved in approximately 60% to 70% of patients with macula-on detachments. Even in macula-off detachments, visual recovery to 20/50 or better occurs in about 40% to 50% of cases.

Redetachment is the most significant risk, occurring in 10% to 20% of cases after primary scleral buckling. Causes include missed retinal breaks, inadequate cryotherapy, buckle malposition, or the development of new breaks. Redetachment typically requires additional surgery, often combining scleral buckle revision with vitrectomy. Proliferative vitreoretinopathy (PVR), the formation of scar-like membranes on the retinal surface that contract and re-detach the retina, is the leading cause of surgical failure and occurs in approximately 5% to 10% of cases.

Refractive change (induced myopia) is one of the most common side effects, occurring in virtually all patients with encircling bands. The buckle increases the axial length of the eye, typically inducing 1 to 3 diopters of myopic shift. This change is permanent and may require updating glasses or contact lens prescriptions. Diplopia (double vision) occurs in 3% to 10% of cases due to disturbance of the extraocular muscles during surgery, altered globe position from the buckle, or muscle imbalance. Most cases resolve spontaneously within weeks to months, but persistent diplopia may require strabismus surgery or buckle modification.

Buckle-related complications include infection (1-2%), extrusion (the buckle eroding through the conjunctiva, 2-5%), and buckle migration or displacement. Anterior segment ischemia can occur if excessive scleral indentation or muscle manipulation compromises ciliary artery blood flow, presenting as anterior chamber inflammation, corneal edema, and pain. Subretinal hemorrhage during drainage of subretinal fluid occurs in approximately 1% to 3% of cases when drainage is performed. Vitreous hemorrhage, choroidal detachment, and raised intraocular pressure are additional complications, each occurring in fewer than 5% of cases.

Recovery from scleral buckling surgery is gradual, with the first 1 to 2 weeks involving the most significant discomfort and visual disruption. Patients typically experience moderate eye pain, foreign body sensation, swelling and redness of the eyelids and conjunctiva, and blurred vision in the immediate post-operative period. Pain is managed with oral analgesics and topical anti-inflammatory eye drops. Cold compresses applied to the closed eyelid help reduce swelling. Most patients use antibiotic and steroid eye drops for 4 to 6 weeks post-operatively.

Vision is usually blurry for the first several weeks as subretinal fluid absorbs and the retina gradually reattaches and recovers function. Patients should avoid heavy lifting, strenuous exercise, and activities that increase intraocular pressure (such as straining or bending over) for 2 to 4 weeks. Swimming and contact sports should be avoided for at least 6 weeks. Most patients can return to desk work within 1 to 2 weeks, though visual demands may require longer recovery.

Follow-up visits are scheduled at 1 day, 1 week, 2 weeks, 4 to 6 weeks, 3 months, 6 months, and then annually after surgery. At each visit, the surgeon examines retinal attachment status, buckle position, intraocular pressure, and visual acuity. Refraction for new glasses is typically performed at 6 to 8 weeks once the eye has stabilized. Long-term follow-up is important because the fellow (unoperated) eye has a 10% to 15% lifetime risk of retinal detachment, and patients should be educated about symptoms of new detachment (flashes, floaters, visual field loss) requiring emergency evaluation.

The cost of scleral buckling surgery depends on geographic location, surgical facility, the complexity of the detachment, and whether the procedure is performed as an emergency or scheduled case. In the United States, total costs for scleral buckling typically range from $6,000 to $15,000, including surgeon fees, facility charges, anesthesia, and post-operative care. In the United Kingdom, NHS covers emergency retinal detachment surgery; private costs range from 3,000 to 8,000 GBP. Medical tourism destinations such as India offer the procedure at $1,500 to $4,000.

Key cost factors include the type of buckle material used (segmental sponge vs. encircling band), whether the procedure is performed under local or general anesthesia, operating room time, and whether additional procedures such as subretinal fluid drainage or intravitreal gas injection are needed. Post-operative medications (antibiotic and steroid eye drops) add a modest cost, and new prescription glasses may be needed due to refractive change. If the initial surgery is unsuccessful and re-operation is required, costs increase accordingly.

Scleral buckling for retinal detachment is considered a medically necessary procedure and is covered by virtually all health insurance plans and national health systems. However, out-of-pocket costs for deductibles, co-pays, and out-of-network providers can be significant. Patients should confirm coverage and obtain pre-authorization when possible. For medical tourists, the total cost package should include preoperative evaluation, the surgical procedure, post-operative medications, follow-up visits for at least 6 weeks, and contingency for re-operation if needed. Arrangements for emergency care capability at the destination are essential given the urgent nature of retinal detachment management.

Pars plana vitrectomy (PPV) is the primary alternative to scleral buckling for retinal detachment repair. Vitrectomy involves removing the vitreous gel from inside the eye, directly visualizing and treating retinal breaks with laser or cryotherapy, and using gas (SF6 or C3F8) or silicone oil as internal tamponade to hold the retina in place while it heals. PPV is preferred for pseudophakic patients, those with posterior breaks, cases with significant vitreous opacity or hemorrhage, and advanced PVR. Its main disadvantages include accelerated cataract formation in phakic patients and the need for strict post-operative positioning.

Combined scleral buckling with vitrectomy offers the advantages of both techniques and is used for complex retinal detachments, particularly those with multiple breaks in different quadrants, PVR, or giant retinal tears. The combined approach achieves higher primary success rates (90-95%) in complex cases compared to either technique alone but involves longer operating time and a slightly higher complication profile. Some surgeons advocate combined surgery as a primary approach for all detachments.

Pneumatic retinopexy is a less invasive office-based alternative for selected retinal detachments with a single break or a small cluster of breaks in the superior retina. It involves injecting an expansile gas bubble into the vitreous cavity and applying cryotherapy or laser around the break. Success rates are 60% to 80% with a single procedure. It is the least invasive option but has the narrowest indications and highest re-operation rate. Laser barricade retinopexy can be used for subclinical retinal detachments (those without symptoms and limited in extent) to create a barrier that prevents progression, though this does not reattach already detached retina.
