Surgery for a corneal ulcer costs roughly $800 to $3,500, depending on the type of ulcer and the procedure needed.
Before the cost, the urgent part.
An ulcer that is getting worse is an emergency today
Eyes deteriorate faster than owners expect. A deep ulcer can perforate within hours, and a perforated eye is a far worse problem with a far worse outcome.
Go immediately for:
- A visible hole, dimple or crater in the surface of the eye
- The eye suddenly cloudy, blue or with something bulging through the surface
- Severe squinting, pawing, and the eye held shut
- Blood inside the eye
- An ulcer under treatment that is larger, deeper or more painful than yesterday
That last one matters most. Owners are often reassured by "we'll recheck in a week", and a deteriorating ulcer does not have a week.
The ladder — and why quotes vary so much
Different practices quote very different numbers because they are treating very different problems.
Simple superficial ulcers. A scratch to the surface layer. These heal on antibiotic drops and pain relief within about a week, cost very little, and need no surgery at all. Most ulcers are these.
Indolent ulcers (SCCEDs). The frustrating one. The surface layer will not stick down to the tissue beneath, so the ulcer sits there for weeks refusing to heal. Classic in middle-aged Boxers and many other breeds. Treatment is debridement followed by a grid keratotomy or diamond burr debridement — usually under sedation, moderate cost, and generally successful. It quite often takes more than one attempt, which is normal rather than a sign anything has gone wrong.
Deep ulcers, melting ulcers and descemetoceles. These need surgery. A conjunctival pedicle graft is the workhorse: a flap of the eye's own conjunctiva is dissected and sutured over the defect, bringing blood supply and structural support to an area at risk of rupturing. This is referral-level microsurgery and priced accordingly.
"Melting" ulcers
The name is accurate and alarming, and it deserves to be.
Enzymes — from bacteria such as Pseudomonas, and from the eye's own inflammatory cells — digest the corneal tissue, sometimes over hours. These need intensive medication, occasionally hourly around the clock, and frequently urgent surgery.
If you have been told your dog has a melting ulcer, treat every instruction about drop frequency as literal.
Why flat-faced breeds
Pugs, Shih Tzus, French Bulldogs, Boston Terriers, Pekingese and Persians are heavily over-represented, and three things combine:
- Prominent eyes with less protection from the skull
- Incomplete blinking, so the surface dries
- Reduced corneal sensation, meaning less blinking reflex and less obvious pain
If you own one of these breeds, treat any eye change as urgent. That single habit prevents a great deal of damage.
Cats are different
In cats, feline herpesvirus is the dominant cause of corneal ulceration. Debridement — the standard treatment for an indolent ulcer in a dog — can make herpetic ulcers considerably worse.
Treatment is antiviral rather than surgical. This distinction matters, and it is why a cat's ulcer is not managed like a dog's.
After a graft
- A cone at all times for several weeks, without exception
- Multiple daily drops, often several different ones on different schedules
- Rechecks frequently at first, then spacing out
- A permanent scar where the graft sits
That last point is worth setting straight. A successful graft leaves a visible pink or white mark that fades over months but does not disappear, and vision through that area is reduced. The eye is saved, but it does not become clear again. Owners routinely expect a perfect eye and feel let down by an excellent result.
Some grafts are trimmed at a second procedure months later to improve appearance and vision.
Who isn't a candidate
- Other: A simple superficial ulcer that will heal on medication alone — most ulcers do, and surgery is for those that will not or cannot.
- Other: Suspected feline herpesvirus ulceration, where debridement can make things considerably worse; cats are handled differently from dogs and this distinction matters.
- Other: An eye that is already blind, painful and structurally ruined, where enucleation is the kinder and cheaper answer than a graft that may fail.
Common questions
How much does corneal ulcer surgery cost for a dog?
Roughly $800 to $3,500. Debridement with a grid keratotomy or diamond burr for an indolent ulcer sits at the lower end and is often done under sedation. A conjunctival pedicle graft for a deep or melting ulcer is referral-level microsurgery under general anaesthesia and sits at the top, plus follow-up visits.
Can a corneal ulcer heal without surgery?
Most can. Simple superficial ulcers heal on antibiotic drops and pain relief within about a week. Surgery is for ulcers that will not heal — indolent ulcers where the surface will not adhere — or that are too deep to be left, where a graft supports the cornea and prevents rupture.
What is an indolent ulcer in dogs?
A superficial ulcer where the surface layer will not attach to the tissue beneath, so it persists for weeks despite treatment. Middle-aged Boxers are classically affected but many breeds get them. Treatment is debridement followed by grid keratotomy or diamond burr debridement, and it sometimes takes more than one attempt.
Will my dog go blind from a corneal ulcer?
Most ulcers heal without affecting vision. Deep ulcers that are grafted leave a permanent scar, so vision through that area is reduced but the eye is saved and remains functional. The serious risk is perforation, which can happen within hours in a deteriorating deep or melting ulcer and can cost the eye.
What is a conjunctival graft in dogs?
A flap of the eye's own conjunctiva, dissected and sutured over a deep corneal defect. It brings blood supply and structural support to an area at risk of rupturing. It leaves a permanent scar that fades over months, and is sometimes trimmed at a later procedure to improve appearance and vision.
