Yes, dogs can have cataract surgery, and it is often the most effective way to restore their vision

Cataract surgery in dogs works much like it does in humans. A veterinary surgeon removes the clouded lens and usually replaces it with an artificial intraocular lens (IOL). The procedure takes about 15 minutes per eye and is performed under general anesthesia. Success rates are high — studies show that 80 to 90 percent of dogs regain useful vision after surgery, and many see as well as they did before cataracts formed.

The decision to pursue surgery depends on how much the cataracts are affecting your dog's quality of life, your dog's overall health, and your ability to manage post-surgery care. A veterinary ophthalmologist (a vet who specializes in eye surgery) will examine your dog to determine whether surgery is a realistic option.

Key Takeaways

  • Cataract surgery restores vision in most dogs and involves removing the clouded lens and usually inserting an artificial lens.
  • A veterinary ophthalmologist must examine your dog first to check for other eye problems and overall health before recommending surgery.
  • Surgery costs between $2,500 and $4,000 per eye and is not covered by most pet insurance plans, though some policies offer partial reimbursement.
  • Recovery takes 2 to 4 weeks, and your dog will need eye drops multiple times daily and strict activity restriction during that time.
  • Dogs with uncontrolled diabetes, severe dry eye, or retinal disease may not be good candidates for surgery.

How to know if your dog is a candidate for surgery

Not every dog with cataracts should have surgery. Your veterinary ophthalmologist will run several tests before recommending the procedure. They will check your dog's retina using an ultrasound or electroretinogram (ERG) to make sure the light-sensing cells at the back of the eye still work. If the retina is damaged, surgery will not restore vision because the eye cannot process light signals.

Your vet will also assess your dog's overall health. Dogs with uncontrolled diabetes are poor candidates because high blood sugar slows healing and increases infection risk. Severe dry eye (keratoconjunctivitis sicca, or KCS) is another barrier — the eye needs adequate tear production to heal properly after surgery. Your vet may recommend treating dry eye first, then reassessing whether surgery is possible.

Age alone is not a disqualifying factor. Older dogs can have successful cataract surgery if they are otherwise healthy and can tolerate anesthesia. Your vet will discuss your dog's specific health history and any medications they take.

What the surgery involves and what to expect during recovery

The procedure itself is outpatient surgery — your dog goes home the same day. The surgeon makes a small incision in the eye, uses ultrasound to break up the clouded lens (a process called phacoemulsification), and removes the pieces. If your dog is a good candidate, an artificial lens is inserted to restore focus. If not, your dog will still see better without the cataract, though vision will be slightly blurry.

Recovery is strict for the first two to four weeks. Your dog must wear a protective cone (Elizabethan collar) to prevent scratching or rubbing the eye. Activity must be limited — no running, jumping, or rough play. You will need to give eye drops four to six times daily, sometimes more. These drops prevent infection, reduce inflammation, and help the eye heal. Your vet will provide a detailed schedule and show you how to administer them without touching the eye.

Most dogs adjust quickly to the cone and restricted activity. Swelling and mild discharge are normal in the first week. You should contact your vet if you see excessive discharge, redness that worsens after day three, or if your dog seems to be in pain. Follow-up exams are scheduled at one week, two weeks, and six weeks after surgery.

Cost and what pet insurance may cover

Cataract surgery typically costs between $2,500 and $4,000 per eye, depending on your location, the surgeon's experience, and whether complications arise. This includes the pre-surgery exam, the procedure itself, and the first few post-surgery visits. If both eyes need surgery, many surgeons recommend operating on one eye first, waiting a few weeks, then doing the second eye.

Most standard pet insurance plans do not cover cataract surgery because they classify it as a pre-existing condition once cataracts are diagnosed. However, some insurers offer accident-and-illness plans that may reimburse a percentage of the cost if the policy was purchased before cataracts were detected. A few plans specifically cover hereditary cataracts in certain breeds. Contact your insurance company to ask what your policy covers — the answer varies widely by plan and provider.

Some veterinary schools and teaching hospitals offer reduced-cost surgery performed by students under supervision. If cost is a barrier, ask your regular vet whether a teaching hospital near you offers this option.

Alternatives if surgery is not possible or chosen

If your dog is not a candidate for surgery or you decide not to pursue it, cataracts will continue to progress and eventually cause blindness. However, many dogs adapt well to vision loss, especially if it happens gradually. Dogs rely heavily on smell and hearing, and a blind dog can live a full, happy life with some environmental adjustments.

There is no medication or eye drop that reverses cataracts or stops them from forming. Some older research suggested that certain supplements might slow progression, but current evidence does not support this. Your vet may recommend antioxidant supplements or omega-3 fatty acids for general eye health, but these will not prevent or treat cataracts.

If your dog is going blind, your vet can help you make your home safer by keeping furniture in consistent places, using baby gates to block stairs, and maintaining a predictable routine. Many dogs who lose vision gradually do not show obvious signs of distress and continue to enjoy their lives.

Hereditary cataracts and breed-specific considerations

Some dog breeds are genetically predisposed to cataracts, including Poodles, Cocker Spaniels, Boston Terriers, and Siberian Huskies. If your dog is from a breed with hereditary cataracts, your vet may recommend surgery sooner rather than later, because these cataracts often progress quickly and can lead to secondary glaucoma (increased eye pressure) if left untreated.

If you have a young dog with hereditary cataracts, surgery can restore vision during their most active years. Breeders of dogs with hereditary cataracts should screen their breeding dogs with a veterinary ophthalmologist and avoid breeding dogs that carry the gene, though this is not always done.

Questions to ask your veterinary ophthalmologist

Before committing to surgery, write down these questions and bring them to your consultation:

  • What is the condition of my dog's retina, and will it support vision after surgery?
  • Does my dog have any other eye problems that might affect the outcome?
  • Is my dog healthy enough for general anesthesia, or do you recommend additional pre-surgery bloodwork?
  • What is your success rate for dogs like mine, and what complications have you seen?
  • Will you use an artificial lens, or will my dog see without one?
  • What is the total cost, and what is included in that price?
  • What happens if complications occur during or after surgery?
  • How long will recovery take, and what restrictions will my dog need?

Frequently Asked Questions

How long does a dog have before cataracts cause blindness?

This varies widely. Some dogs develop cataracts slowly over years, while others progress to blindness in months. Hereditary cataracts in young dogs often progress faster than age-related cataracts in seniors. Your vet can estimate progression based on how much of the lens is clouded and how quickly changes are happening at your dog's check-ups.

Can cataracts come back after surgery?

True cataracts do not return, but a condition called posterior capsular opacification (PCO) can develop in the membrane left behind after lens removal. This occurs in about 20 percent of dogs within a few years of surgery. PCO is usually mild and does not require treatment, but if it affects vision, a quick laser procedure can clear it.

What if my dog goes blind before I can afford surgery?

Dogs adapt to blindness better than many people expect. Keep your home layout consistent, use verbal cues, and avoid moving furniture. Your dog will navigate using smell and memory. Many blind dogs live comfortably for years. Talk to your vet about safety modifications and whether your dog shows signs of pain or distress.

Is cataract surgery painful for dogs?

The surgery itself is painless because your dog is under general anesthesia. After surgery, mild discomfort is normal for a few days, similar to a scratchy feeling in the eye. Your vet will prescribe pain medication if needed. Severe pain is not normal and should be reported when ready.

Can I use human eye drops on my dog after surgery?

No. Human eye drops are formulated differently and may irritate a dog's eye or interfere with healing. Use only the drops your veterinary surgeon prescribes. If you run out before your next appointment, contact your vet — do not substitute.
