Yes, dogs can have cataract surgery, and it's the only way to restore vision once a cataract forms

A cataract in a dog's eye clouds the lens the same way it does in humans. Unlike in people, where glasses or drops might slow early cataracts, dogs have no non-surgical options. Once a cataract blocks enough light, surgery is the only treatment that restores sight. The surgery itself — phacoemulsification, the standard procedure — removes the clouded lens and usually implants an artificial one. Most dogs see well afterward, though some adjust to life without the lens if surgery isn't an option.

The decision to operate depends on how much the cataract affects your dog's vision, your dog's overall health, and the cost. A cataract that hasn't yet caused blindness may not need when ready surgery. A cataract that has already blinded one or both eyes is urgent, because the longer you wait, the higher the risk of complications like lens rupture or inflammation that can make surgery harder or impossible.

Key Takeaways

  • Cataract surgery in dogs uses phacoemulsification to remove the clouded lens and restore vision, and it's the only treatment that works once a cataract forms.
  • Surgery costs between $1,500 and $3,500 per eye at most veterinary ophthalmology clinics, and pet insurance may cover part of it if cataracts aren't listed as a pre-existing condition.
  • Your dog must be in good overall health and have no other eye diseases like glaucoma or retinal problems before surgery can be recommended.
  • Recovery takes two to four weeks, and your dog will need antibiotic and anti-inflammatory eye drops multiple times daily during that time.
  • If surgery isn't an option, most dogs adapt to blindness and live normal lives with familiar surroundings and consistent routines.

How cataract surgery works in dogs

The surgeon uses an ultrasonic probe to break up the clouded lens into tiny pieces, then suctions those pieces out through a small incision. This is phacoemulsification, and it's gentler on the eye than older surgical methods. The incision is usually so small it doesn't need stitches.

After the lens is removed, the surgeon typically implants an artificial intraocular lens (IOL). This restores the eye's ability to focus light onto the retina, so your dog's vision is closer to normal. Some dogs do well without an implanted lens — they see, but with less sharp focus — though this is less common in dogs than in humans.

The whole procedure takes 10 to 20 minutes per eye. Your dog will be under general anesthesia, so pre-surgery bloodwork and a physical exam are required to make sure your dog can safely handle anesthesia.

What cataract surgery costs and whether insurance covers it

Cataract surgery at a veterinary ophthalmology clinic typically costs $1,500 to $3,500 per eye. The price depends on the clinic's location, the surgeon's experience, whether an artificial lens is implanted, and whether complications arise during surgery. A general veterinarian cannot perform this surgery — you will need a referral to a board-certified veterinary ophthalmologist.

Pet insurance may cover part of the cost if your policy includes surgery coverage and cataracts are not listed as a pre-existing condition. Check your policy documents or call your insurer before scheduling surgery. Some policies have annual caps or require you to pay upfront and then seek reimbursement. If your dog was diagnosed with cataracts before you bought insurance, that condition is usually excluded.

If cost is a barrier, ask the ophthalmology clinic whether they offer payment plans or know of financial information programs. Some clinics work with organizations that help pay for surgery in cases of financial hardship, though these are not common.

Health screening before surgery can happen

Before a veterinary ophthalmologist will recommend surgery, your dog must have a full eye exam to rule out other problems that would make surgery risky or unsuccessful. The surgeon will check for glaucoma (high pressure inside the eye), retinal disease, lens rupture, or severe inflammation. Any of these can mean surgery won't restore vision or could make things worse.

Your dog will also need bloodwork and a physical exam to confirm they're healthy enough for general anesthesia. Older dogs or dogs with heart, kidney, or liver disease may still be candidates, but the anesthesia risk is higher and must be weighed against the benefit of restored vision.

If your dog has cataracts in both eyes, the surgeon will usually operate on one eye first, wait a week or two for it to heal, then do the second eye. This lets the first eye recover and gives you a chance to see how well your dog adapts to the new vision before committing to a second surgery.

Recovery and aftercare at home

Recovery takes two to four weeks. During this time, your dog will need antibiotic eye drops and anti-inflammatory drops (usually a steroid) multiple times daily — often four to six times per day for the first week, then tapering down. You will also need to prevent your dog from rubbing or scratching the eye, which means an Elizabethan collar (cone) for at least the first two weeks.

Keep your dog calm and avoid rough play, jumping, or swimming during recovery. Restrict exercise to short, leashed walks. Dust, dirt, and water can irritate the healing eye, so keep your dog away from dusty areas and don't bathe your dog's face.

Your dog will have follow-up exams at one week, two weeks, and four weeks after surgery. The surgeon will check that the eye is healing, the artificial lens is in place, and inflammation is decreasing. If you notice discharge, swelling, redness, or if your dog seems to be in pain, contact the surgeon right away — these can be signs of infection or other complications.

What to expect if your dog doesn't have surgery

If surgery isn't an option — because of cost, health problems, or other reasons — your dog can still live a full life. Dogs rely much less on vision than humans do. They navigate by smell, hearing, and memory of their surroundings. A dog that goes blind gradually (as happens with cataracts) often adapts better than one that loses sight suddenly.

Keep your home layout consistent so your dog doesn't bump into furniture. Use verbal cues and let your dog follow familiar scents and sounds. Many blind dogs play, eat, sleep, and interact with their families almost normally. Some owners find that a blind dog is actually calmer and less reactive to visual stimuli.

Even without surgery, your dog should still see an ophthalmologist once to rule out glaucoma or other painful conditions that need treatment. Glaucoma can cause severe pain even if the eye is already blind, so it's important to know whether it's present.

Complications and long-term outcomes

Most dogs have good outcomes after cataract surgery. Vision improves in 80 to 90 percent of cases. The most common complications are inflammation inside the eye (uveitis), which is usually controlled with drops, and a condition called posterior capsular opacification, where scar tissue clouds the back of the lens implant. This can sometimes be treated with a laser procedure.

Rarely, the artificial lens can move out of position or the eye can develop glaucoma months or years after surgery. This is why long-term follow-up exams are important. Your dog should see the ophthalmologist once a year after surgery to check for these late complications.

If your dog had cataracts in one eye and the surgery was successful, there's a good chance cataracts will eventually form in the other eye. This is especially true if cataracts are hereditary in your dog's breed. Discuss with your ophthalmologist whether your dog should have the second eye done preventively or whether you should wait and see.

Frequently Asked Questions

How old does a dog have to be to have cataract surgery?

There's no strict age limit. Puppies can have cataracts (usually inherited) and can have surgery. Older dogs can have surgery as long as they're healthy enough for anesthesia. The decision is based on your dog's overall health, not age alone. Your veterinarian can help you decide whether the risks of anesthesia outweigh the benefit of restored vision.

Will my dog's vision be as good as it was before the cataract?

Usually yes, especially if an artificial lens is implanted. Most dogs see nearly as well as they did before. However, the artificial lens doesn't adjust focus the way a natural lens does, so your dog may see distance and close-up objects slightly differently than before. Most dogs adapt quickly.

Can cataracts come back after surgery?

The cataract itself won't return in the eye that was operated on, because the clouded lens has been removed. However, cataracts can form in the other eye if your dog has both eyes affected. Scar tissue can also cloud the back of an artificial lens over time, but this is usually treatable.

What if my dog has cataracts in both eyes — do I have to do both at once?

No. Surgeons typically operate on one eye first, wait one to two weeks for it to heal, then do the other eye. This approach is safer because it lets your dog recover from anesthesia once and gives you time to see how the first eye heals before committing to a second surgery.

Is there any medicine that can stop a cataract from getting worse?

No medication has been proven to stop or reverse cataracts in dogs. Some supplements claim to slow cataract progression, but there's no strong evidence they work. Surgery is the only treatment that restores vision once a cataract forms.
