Crossed eyes aren’t just a childhood condition. An estimated 4% of the US population has strabismus — misaligned eyes — and a significant portion are adults who either never had it corrected or whose alignment has shifted over time. Surgery is often the best solution for both groups. And it’s more affordable than most people expect, especially with medical insurance.
What Is Strabismus Surgery?
Strabismus surgery corrects misalignment of the eyes by adjusting the tension in the eye muscles — either weakening overactive muscles (by moving their attachment point further back on the eye) or tightening underactive ones (by removing a section of muscle to shorten it). It’s done under general anesthesia in children and local or general anesthesia in adults.
The American Association for Pediatric Ophthalmology and Strabismus (AAPOS) estimates that 3–4% of children have strabismus, and the condition is one of the most common reasons children see a pediatric ophthalmologist. In 2022, the AAO noted that adult strabismus surgery has increased significantly over the past decade — driven by adults correcting childhood strabismus and acquired cases from neurological conditions, thyroid eye disease, and other causes.
Cost Breakdown: What You’ll Pay
The total cost depends on whether one or both eyes need surgery (many cases involve both), the setting (ASC vs. hospital), and the complexity.
| Cost Component | Uninsured Estimate | With Insurance (typical OOP) |
|---|---|---|
| Pediatric ophthalmologist fee (1 eye) | $1,800–$3,500 | $200–$700 coinsurance |
| Pediatric ophthalmologist fee (2 eyes) | $2,500–$4,500 | $300–$900 coinsurance |
| Anesthesia (general, children) | $800–$1,500 | $100–$400 |
| Anesthesia (local/MAC, adults) | $400–$800 | $75–$250 |
| Facility fee (ASC) | $3,500–$7,000 | $500–$1,800 |
| Facility fee (hospital OR) | $7,000–$14,000 | $1,000–$3,500 |
| Post-op visits | $100–$200 each | Specialist copay each |
| Adjustable suture fee (adult cases) | $300–$800 | Often covered |
| Total typical range (ASC, uninsured) | $6,100–$13,000 | $800–$2,900 |
Pediatric vs. Adult: What’s Different
Children almost always receive general anesthesia — they can’t cooperate with local anesthesia for a delicate eye muscle procedure. General anesthesia for kids costs more than MAC sedation for adults, and it adds to the requirement for a hospital or ASC with full pediatric anesthesia capabilities.
Adults have the option of adjustable sutures — a technique where the surgeon uses a slip-knot that can be refined in the office the next day while the patient is awake and cooperative. Adjustable sutures improve alignment accuracy and reduce the need for reoperation. This adds a modest fee ($300–$800) but is often covered by insurance and is generally worth it for adult cases.
Yes — strabismus surgery is medically necessary and covered under medical insurance for both children and adults. Unlike cosmetic procedures, misaligned eyes affect binocular vision, depth perception, and sometimes amblyopia (lazy eye). Insurers routinely authorize it. Confirm CPT code 67311–67318 is covered under your plan and that your surgeon is in-network before scheduling.
How Many Surgeries Will You Need?
Strabismus surgery is remarkably effective, but it’s not always a one-and-done procedure. Research from the AAO shows that approximately 20–30% of strabismus patients require a second surgery to achieve optimal alignment — particularly for large-angle or complex deviations. Plan your budget accordingly.
For children with esotropia (crossed eyes turning inward), a single surgery has high success rates. For adults with long-standing exotropia or cases caused by thyroid eye disease, two or more surgeries over time are more common.
Post-op prism glasses are sometimes needed temporarily while the eyes re-learn to work together — these add $100–$400 to your costs.
What Affects Cost Most
Number of muscles operated on: One muscle = lower cost; four muscles (both eyes, two muscles each) = significantly higher surgeon and anesthesia fees.
Complexity of the deviation: Large angles, prior surgery, or restrictive causes (like thyroid eye disease) add surgical time and complexity.
Geography: Pediatric ophthalmologists in major metro areas charge 20–40% more than regional centers.
Facility choice: An ASC runs 40–60% cheaper than a hospital OR — appropriate for most straightforward strabismus cases.
Don’t wait too long on pediatric strabismus. In children under 8, untreated strabismus can cause amblyopia (lazy eye) as the brain suppresses input from the misaligned eye. Early surgery — often combined with patching therapy — gives children the best chance of developing normal binocular vision. Every year of delay after age 7–8 reduces the potential visual improvement.
Financing and Cost Reduction Strategies
- Confirm ASC eligibility first — most strabismus cases qualify. ASCs save $3,000–$7,000 on facility fees.
- Ask about the OOP maximum — if your child has had other procedures (tonsils, ear tubes, etc.) earlier in the year, you may be close to your annual OOP max.
- Use an HSA or FSA — strabismus surgery is fully FSA/HSA eligible for both the child and the parent’s account covering dependent children.
- Request the itemized estimate in advance — most surgical practices will give you a written estimate. Compare ASC vs. hospital charges side by side.
- CareCredit — widely accepted at pediatric ophthalmology practices for the patient portion.
Questions to Ask Your Surgeon
- Are you recommending adjustable sutures for my adult case?
- How many muscles will you operate on?
- What’s your personal reoperation rate for this type of strabismus?
- Can this be done at an ASC, or does my child’s age/history require a hospital setting?
- Will prism glasses be needed post-op while alignment stabilizes?
Strabismus surgery has transformed quality of life for millions of patients — improving depth perception, social confidence, and visual function. With medical insurance, it’s one of the more accessible eye surgeries from a cost perspective. The key is planning ahead, choosing an ASC when possible, and picking a surgeon with strong experience in your specific type of deviation.
