Dog Cataract Surgery Cost: The Workup, the Surgery, and Success Rates

Cataract surgery by phacoemulsification typically runs $2,700 to $4,500 for both eyes in 2026 at a boarded veterinary ophthalmologist, with some practices pricing per eye in the $1,600 to $2,500 range. The pre-surgical workup is separate and not optional: an electroretinogram (ERG) to confirm the retina still functions costs $300 to $600, and ocular ultrasound adds roughly $150 to $400. Add rechecks and post-operative medications and a realistic total lands between $3,500 and $5,500. Prices vary by region and clinic, and referral centers in major metros sit at the top of every range.

This is general information, not veterinary advice. Any eye that is red, painful, squinting, tearing heavily, or suddenly clouded needs a veterinarian now — especially in a diabetic dog, where cataract formation can trigger lens-induced uveitis and, untreated, glaucoma that ends vision permanently.

Why the Workup Comes Before the Surgery

Surgery on an eye with a dead retina restores nothing. That single sentence explains the ERG. The test measures electrical response from the retina and tells the ophthalmologist whether the eye can still see once the cloudy lens is removed. Ultrasound looks through the cataract to check the back of the eye for detachment, hemorrhage, or tumor. Skipping these steps to save $450 to $1,000 risks paying for surgery that cannot work. Bloodwork and a general health screen are usually required too, because the patient has to be a safe anesthesia candidate.

What the Surgery Involves

Phacoemulsification uses ultrasound to break up the clouded lens and removes it through a small incision, and an artificial lens is usually implanted. It is microsurgery, performed under general anesthesia by a veterinarian who has completed a residency in ophthalmology. Most patients go home the same day or the next morning.

Success Rates, Stated Honestly

At a boarded ophthalmologist, with a well-selected patient and a dedicated owner, vision restoration runs about 90 to 95 percent. That is a strong number, and it is also conditional. It assumes the retina works, the eye is not already inflamed beyond control, and the post-operative regimen is followed closely. Complications exist — glaucoma, retinal detachment, infection, and capsular opacification — and some require a second procedure. Ask the surgeon for their own complication rate, not a general figure.

The Diabetes Connection

Most diabetic dogs develop cataracts, often quickly — sometimes within months of diagnosis, occasionally within weeks. Good glucose control reduces the risk but does not eliminate it, and owners should hear that early rather than discover it as a surprise. Diabetic cataracts are also more likely to cause lens-induced uveitis, an inflammation that damages the eye while the cataract is “just being watched.” That is why monitoring and anti-inflammatory drops can be part of a wait-and-see plan, and why the wait-and-see plan still requires rechecks and money. There are no drug dosages on this page for a reason: the eye medications are prescribed and adjusted by the veterinarian treating that specific eye.

The Weeks After Surgery Are Part of the Cost

Post-operative care is a schedule, not a single visit. Expect multiple medicated eye drops several times a day for weeks, tapering over time, plus an Elizabethan collar for roughly two to four weeks, restricted activity, and rechecks at set intervals — commonly several in the first three months. Budget $100 to $300 for medications over the course of recovery, plus $50 to $150 per recheck. Owners who work long shifts or travel should arrange help in advance; missed drops are a leading cause of poor outcomes, and that is a cost in outcome, not just dollars.

Not Every Cataract Needs Surgery

Small, incomplete, or peripheral cataracts may never take meaningful vision, and some sit unchanged for years. The ophthalmologist’s staging — location, density, and how much of the lens is involved — decides whether surgery is worth the risk now, later, or never. A general practitioner can see that a cataract is present; grading it and judging the retina beneath it is ophthalmology work. If the recommendation is to wait, the plan should still include what to watch for and how often to recheck.
