A corneal repair on a cat costs 650 to 3,400 in the US, 550 to 2,820 GBP in the UK, and 1,700 to 11,100 CNY in China, and the number is set by depth rather than by the length of the cut. A 4 mm scratch that stays in the surface layer is a 450 to 800 procedure. The same 4 mm, once it reaches the stroma or punches through, becomes 850 to 1,600, then 1,700 to 2,900. Owners are quoted wildly different figures for what sounds like one injury because 3 different grades are being priced.
Depth, not length, decides the bill
Every estimate on this page has the same 3 layers: a workup, the repair itself, and 14 to 21 days of aftercare. The grading below follows what the surgeon sees at the slit lamp, and the grade picks the technique, the suture count, and the table time.
| Grade | What is done | US (USD) | UK (GBP) | China (CNY) |
|---|---|---|---|---|
| 1: surface only | 0-4 sutures, 10-20 minutes, bandage lens | 450-800 | 380-650 | 1,200-2,600 |
| 2: into the stroma | 6-14 sutures at 9-0 or 10-0, lid closure 24-72 hours | 850-1,600 | 700-1,300 | 2,500-5,500 |
| 3: perforation | Conjunctival graft or adhesive plus bandage lens, 45-90 minutes | 1,700-2,900 | 1,400-2,400 | 5,000-9,500 |
| Workup | Stain, pressure, tear test, depth measure, 10-15 minutes | 120-300 | 100-250 | 300-900 |
| Aftercare | 14-21 days, 2-3 rechecks, cone, 1 stain at day 7 | 80-200 | 70-170 | 200-700 |
At 7.2 CNY to the dollar, the same grade lands 2 to 3 times higher in the US or the UK than in China, and the multiple grows with the grade: grade 1 is close to 2 times, grade 3 is nearer 3. Grade 3 is where the gap is made, because a graft needs a surgeon who does them weekly, and those sit in cities where the hourly rate is already the highest in the country.
Grade 1: 450 to 800 buys 20 minutes and 0 to 4 sutures
A defect that has not broken the surface layer often needs no suture at all. The surgeon debrides loose tissue, places a bandage contact lens, and closes the eyelids with 1 to 3 temporary stitches for 24 to 72 hours so the lid acts as a living bandage. Table time is 10 to 20 minutes, and the whole visit can be under 1 hour. This is also the grade where a general practice will operate, which is why the low end is 450 and not 1,200.
Grade 2: 850 to 1,600 once the stroma opens
Stromal loss means load-bearing tissue is gone. Sutures run 6 to 14, placed 1 to 2 mm apart with 9-0 or 10-0 material, and each one has to be tight enough to seal and loose enough not to cut through 0.5 mm of tissue. The eye is usually closed for 24 to 72 hours afterwards, and the cat is on a cone for 14 days. A quiet eye that starts to water and squint at day 3 is the pattern that sends a grade 2 back to the table, and a second anesthesia is another 350 to 600. Suture spacing also sets the removal date: 21 to 28 days for 9-0 material, and 10 to 14 days for 10-0 in a cat that will not hold still for a slit lamp.
Grade 3: 1,700 to 2,900 and a graft
Once the defect is a descemetocele or a full perforation, the eye is one blink from losing its fluid. Repair is a conjunctival pedicle graft, a small flap of tissue rotated over the hole and sutured at 2 to 4 points, or surgical adhesive with a bandage lens when the hole is under 2 mm. Table time is 45 to 90 minutes and the surgery is done by an ophthalmologist, not a general practitioner. A graft that fails means 1 more procedure at 1,200 to 2,000, so the first attempt is the cheap one.
The 10-minute tests that assign the grade
Four readings decide everything. Fluorescein stain shows the defect and, after 1 minute, whether fluid is leaking through it, which is the difference between grade 2 and grade 3. A depth measurement at the slit lamp separates surface loss from stromal loss. Eye pressure under 8 mmHg suggests the eye is already leaking. A tear reading under 10 mm per minute changes the plan, because a dry cornea heals slowly and a graft on it is at higher risk. All 4 are done in the same 10 to 15 minutes and cost 120 to 300 in the US.
Aftercare: 14 to 21 days, 2 to 3 checks
Rechecks land at day 3, day 7, and day 14 to 21, and each one includes a stain to confirm the defect is shrinking. The cone stays on for the whole stretch, not for the days it looks calm, because 1 rub at day 5 can undo 12 sutures. Suture removal, when non-dissolving material is used, is a separate 60 to 120 visit at 21 to 28 days.
Why 2 quotes 8 km apart differ by 700
The difference is almost always who holds the knife. A general practice that sutures simple defects charges 450 to 900. An ophthalmologist charges 850 to 2,900 for the same eye because the equipment, the graft material, and the surgical time are priced differently. Ask which grade the quote assumes, and ask what happens to the price if the stain at surgery shows a deeper defect than the exam suggested.
When to skip the comparison and go now
A cornea that is leaking, a pupil that is distorted, or a cat that is suddenly squinting and holding 1 eye shut needs to be seen within 24 hours, and a perforation within 6 to 12 hours. Waiting 2 days to compare 3 hospitals is how a 450 grade 1 becomes a 2,900 grade 3. For a wound elsewhere on the body, our page on wound repair covers the same 3-layer split; for a planned operation rather than an emergency, hernia repair shows how much of a bill is anesthesia.

Frequently asked
Can a corneal ulcer heal without surgery and save the 450?
A superficial ulcer that is not infected often closes in 5 to 10 days with a bandage lens and a cone, and that is the 120 to 300 workup plus 2 rechecks rather than 450. The catch is depth: once the stroma is involved or the eye is leaking, waiting turns a 850 repair into a 1,700 to 2,900 graft, and a melting cornea can perforate within 48 hours.
Why do UK quotes look lower than US quotes for grade 3?
They are not, once currency is applied. A 1,400 to 2,400 GBP graft becomes roughly 1,780 to 3,050 USD at 1.27, which sits inside the US band of 1,700 to 2,900. The UK low end looks lower because more of the aftercare is bundled into the surgical fee rather than billed as 2 or 3 separate rechecks at 70 to 170 each.
What happens if the graft fails?
A failed graft shows up as a leaking or bulging site at day 3 to day 10, and the usual next step is a second graft or, if the eye cannot be saved, enucleation. Budget 1,200 to 2,000 for the repeat procedure, and ask before the first surgery whether the quoted fee includes 1 revision or charges it as a new operation.
