A corneal ulcer is a scratch or wound on the surface of the eye. While most superficial ulcers heal with eye drops alone, deep or non-healing ulcers require surgery to prevent eye rupture and vision loss. Corneal ulcers are common in dogs — caused by scratches, foreign objects, trauma, and entropion.
The cost of dog corneal ulcer surgery ranges from $500 for simple debridement to $3,000+ for complex graft surgery, with an average of $1,500.
How Much Does Corneal Ulcer Surgery Cost?
| Procedure | Cost Range | When Used |
|---|---|---|
| Medical management (no surgery) | $50–$200 | Superficial ulcers — antibiotic drops, pain medication |
| Debridement + grid keratotomy | $500–$1,000 | Indolent (non-healing) superficial ulcers |
| Conjunctival flap / graft | $1,000–$2,500 | Deep ulcers, descemetoceles |
| Corneal transplant (penetrating keratoplasty) | $2,500–$5,000+ | Full-thickness corneal perforation (rare) |
| Conjunctival pedicle flap | $800–$2,000 | Deep ulcers with risk of perforation |
| Corneoconjunctival transposition | $1,500–$3,000 | Large or central corneal defects |
When Does a Corneal Ulcer Need Surgery?
Most superficial corneal ulcers heal with eye drops within 7–10 days. Surgery is needed when:
- •The ulcer is deep: Penetrates more than 50% of the corneal thickness (risk of perforation).
- •The ulcer won't heal (indolent): Superficial ulcers that haven't healed in 7–14 days despite medical treatment need debridement ($500–$1,000).
- •Descemetocele: The ulcer is so deep that only Descemet's membrane remains — the eye is about to rupture. Emergency surgery required.
- •Corneal perforation: The cornea has ruptured and the eye is open. Emergency surgery to save the eye.
- •Melting ulcer: Bacterial enzymes are dissolving the cornea (especially with Pseudomonas infections). Urgent surgery needed.

| Board-certified ophthalmologist | $700–$1,200 | $1,000–$3,000 |

Causes of Corneal Ulcers in Dogs
- •Trauma: Scratches from branches, claws, or foreign objects. The most common cause.
- •Entropion: Inward-rolling eyelids rub the cornea, causing chronic ulcers.
- •Cherry eye: Exposed gland causes irritation and secondary ulcers.
- •Dry eye (KCS): Insufficient tears lead to corneal drying and ulceration.
- •Foreign body: Plant material, sand, or debris trapped under the eyelid.
- •Chemical burns: Exposure to irritants (shampoo, cleaning products).
- •Facial nerve paralysis: Inability to blink leaves the cornea exposed and dry.
Signs of a Corneal Ulcer
- •Squinting or holding eye closed
- •Excessive tearing
- •Redness of the conjunctiva
- •Cloudy or opaque spot on the eye surface
- •Pawing at the eye
- •Sensitivity to light
- •Discharge (clear, yellow, or green)
- •If you see these signs, take your dog to the vet immediately. A simple superficial ulcer can deepen and threaten the eye within 24–48 hours. Early treatment with eye drops ($50–$200) can prevent the need for surgery ($500–$3,000).
Frequently Asked Questions
How much does corneal ulcer surgery cost for a dog?
Dog corneal ulcer surgery costs $500 to $3,000+ depending on severity. Debridement for non-healing ulcers costs $500–$1,000. Conjunctival flap or graft surgery for deep ulcers costs $1,000–$2,500. Corneal transplant for perforated corneas costs $2,500–$5,000+. Total including blood work, anesthesia, medications, and follow-up is $1,000–$4,500.
Does pet insurance cover corneal ulcer surgery?
Yes, most pet insurance covers corneal ulcer surgery when medically necessary (deep ulcer, non-healing ulcer, perforation). Reimbursement is typically 70–90% after your deductible. Early treatment with eye drops ($50–$200) is also typically covered.
Can a corneal ulcer heal without surgery?
Yes. Most superficial corneal ulcers heal with antibiotic and lubricating eye drops within 7–10 days. Surgery is only needed for deep ulcers, non-healing (indolent) ulcers, or ulcers at risk of perforation. If your dog's ulcer hasn't improved in 7 days, your vet may recommend surgery.
What happens if a corneal ulcer is left untreated?
Untreated corneal ulcers can deepen, leading to descemetocele (pre-perforation), corneal perforation (eye rupture), infection inside the eye (endophthalmitis), and loss of the eye. A $50–$200 treatment with eye drops early on can prevent a $1,000–$5,000 surgery — or eye removal.
How long does corneal ulcer surgery recovery take?
Recovery takes 2–6 weeks depending on the procedure. Debridement: 1–2 weeks. Conjunctival flap: 4–8 weeks (flap is trimmed at 4–6 weeks). Corneal graft: 6–12 weeks. Eye drops are required 3–4 times daily during recovery. E-collar must be worn until the cornea is healed.
