Quick answer: Cataract surgery in dogs (phacoemulsification) breaks up the cloudy lens with ultrasound, removes it through a small incision and usually places an artificial lens. Done by a veterinary ophthalmologist on a dog whose retina tests healthy, it restores functional vision in roughly 85 to 95 percent of cases. Typical US cost is about 2,500 to 5,000 dollars per eye including tests and follow-up, less than double for both eyes together. Recovery means a cone for two to three weeks, drops several times a day for about six weeks, and four to five rechecks. It is worth it when the cataract is affecting daily life, the retina is healthy and the dog is fit for anaesthesia. Small, slow cataracts can be monitored instead.
Who is a candidate
Three questions decide it. Is the retina behind the lens working? An electroretinogram (ERG) measures the retina's electrical response to light, and an ocular ultrasound checks for retinal detachment, since a new lens is pointless in front of a retina that cannot see. Is the eye quiet? Uncontrolled lens-induced uveitis or glaucoma has to be treated first. Is the dog fit for anaesthesia? Bloodwork, heart check, and for diabetics, stable glucose. Age alone is not a barrier; healthy 12 and 13-year-olds have surgery routinely.
What it costs
- Consultation and tests: the ophthalmology exam, ERG and ultrasound are usually a few hundred dollars and are worth doing even if you decide against surgery, because they tell you whether the eye can still see.
- Surgery: roughly 2,500 to 5,000 US dollars per eye all-in, with both eyes in one session typically less than double. Australian and UK prices sit in a similar band in local currency. Prices vary with region, whether an artificial lens is placed, and complication management.
- Aftercare: drops, rechecks and the cone are often bundled; ask.
- Insurance: most pet insurers cover cataract surgery if the condition is not pre-existing, so check the policy wording before the diagnosis is on file.
The procedure
Under general anaesthesia the surgeon makes a small incision at the edge of the cornea, opens the capsule that holds the lens, liquefies the cataract with an ultrasonic probe and suctions it out, then folds an artificial lens into the empty capsule so the dog can focus at normal distances. Both eyes are often done in the same session. The dog goes home the same day or the next morning.
Recovery, week by week
- Days 1 to 3: cone on at all times, several drops a day (anti-inflammatory, antibiotic, sometimes pressure-lowering), oral medication, quiet house, lead walks only. Many dogs are already tracking movement.
- Weeks 1 to 3: recheck at day one and week one; pressure checks; drops continue; no rubbing, swimming, rough play or head-shaking games.
- Weeks 4 to 6: cone off if the surgeon agrees; drops taper; activity returns.
- Months 3 to 12: periodic rechecks for pressure and for scar tissue on the lens capsule, which can be lasered if it clouds.
Complications to know about
Post-operative inflammation is expected and managed with drops. The ones that matter are glaucoma (a minority of eyes, more often in some breeds and in eyes that were inflamed before surgery), retinal detachment (rare, more likely in eyes with pre-existing retinal weakness), capsule opacification (common, treatable) and infection (rare). The surgeon's pre-op assessment is mostly about predicting and preventing these.
When monitoring is the better call
A small cataract that is not affecting daily life, a dog with retinal disease that will not benefit, a dog who is a poor anaesthetic risk, or a family for whom six weeks of drops is not realistic. Monitoring means pressure checks and treating inflammation early.

Supporting the eye before and after
Whether you operate or monitor, the retina and tear film keep working and keep needing nutrients. OcuLabs Vision Support Bites supply lutein 6 mg, astaxanthin 1 mg, beta-carotene 1.5 mg and algal DHA 100 mg per two-chew serving, which is the nutrition veterinary ophthalmologists typically want around surgery. Ask your surgeon when to start it; most are happy with daily eye nutrition once the post-operative drop schedule is settled. It supports the eye; it does not replace the surgery or the drops.
Frequently asked questions
How much does cataract surgery for a dog cost?
Roughly 2,500 to 5,000 US dollars per eye including tests and follow-up; both eyes together for somewhat less than double. Get an itemised quote from a veterinary ophthalmologist.
What is the success rate?
Around 85 to 95 percent of dogs with a healthy retina regain functional vision, and most keep it long term.
How long is recovery?
A cone for two to three weeks, drops for about six weeks, and rechecks at one day, one week, one month and three months.
Can every dog have surgery?
No. The retina must work, the eye must be quiet and the dog fit for anaesthesia.
What if I do not operate?
Many dogs live well with cataracts. The eye needs regular pressure checks and prompt treatment of any inflammation.
