Yes, dogs can have cataract surgery, and it is one of the most successful procedures in veterinary medicine
Dogs develop cataracts much like humans do — the lens becomes cloudy and vision fades. Unlike humans, dogs cannot tell you when they are struggling to see, so many owners do not notice until their dog bumps into furniture or hesitates on stairs. The good news is that cataract surgery in dogs has a high success rate. Most dogs regain useful vision after the procedure, though the timeline and outcome depend on the dog's age, overall health, and how long the cataract has been present.
The surgery itself is performed by a veterinary ophthalmologist — a veterinarian who specializes in eye care — not a general veterinarian. The surgeon removes the cloudy lens and often implants an artificial lens to restore focus. Recovery takes several weeks, and your dog will need close monitoring and medication during that time. The cost is significant (typically several thousand dollars per eye), so understanding what the procedure involves and what to expect afterward helps you make an informed decision.
Key Takeaways
- Cataract surgery in dogs is performed by a veterinary ophthalmologist and has a success rate of 80 to 90 percent for restoring vision.
- The procedure involves removing the cloudy lens and usually implanting an artificial lens to help your dog focus.
- Recovery requires strict activity restriction, multiple eye drops daily, and follow-up visits over several weeks.
- Dogs with diabetes, severe inflammation inside the eye, or other serious health problems may not be good candidates for surgery.
- Cost varies widely but typically ranges from several thousand dollars per eye depending on your location and the surgeon's experience.
How cataract surgery works in dogs
The surgeon makes a small incision in the eye and uses ultrasound (a technique called phacoemulsification) to break up the cloudy lens into tiny pieces, which are then suctioned out. Once the lens is removed, an artificial intraocular lens is inserted into the lens capsule — the membrane that held the original lens. This artificial lens helps your dog's eye focus light onto the retina, restoring clear vision.
The entire procedure usually takes 15 to 20 minutes per eye. Your dog will be under general anesthesia, so a pre-surgery blood test and physical exam are standard to make sure your dog can safely handle anesthesia. If both eyes have cataracts, surgeons typically operate on one eye first, wait a week or two to monitor healing, and then operate on the second eye.
Which dogs are good candidates for surgery
Age alone does not disqualify a dog from surgery. Senior dogs can have cataract surgery if they are otherwise healthy enough for anesthesia. What matters more is whether the cataract is the main reason your dog's vision is failing. If your dog also has retinal disease, glaucoma, or severe inflammation inside the eye, surgery may not restore vision even if the cataract is removed.
Your veterinary ophthalmologist will perform an ultrasound of the eye (called B-scan ultrasonography) to check the health of the retina before recommending surgery. Dogs with uncontrolled diabetes are often poor candidates because high blood sugar can cause new cataracts to form quickly and can slow healing. Dogs with severe dry eye or other surface problems may also face complications during recovery.
What recovery looks like at home
The first two weeks after surgery are the most critical. Your dog must wear a protective collar (cone) at all times to prevent scratching or rubbing the eye. You will need to give eye drops multiple times a day — usually four to six times — to prevent infection and reduce inflammation. Some dogs also receive oral pain medication or anti-inflammatory medication during this period.
Activity must be strictly limited. Your dog should not run, jump, play fetch, or swim for at least two weeks, and often longer. Short, leashed walks on flat ground are fine, but rough play or off-leash activity can damage the surgical site. Your veterinarian will schedule follow-up visits at one week, two weeks, and four weeks after surgery to check healing and adjust medications as needed.
Signs of complications during recovery
Most dogs heal without problems, but watch for redness that does not improve, discharge from the eye, cloudiness that worsens rather than improves, or your dog acting in pain (squinting, pawing at the eye, or reluctance to open the eye). Swelling around the eye or a change in the appearance of the pupil can also signal a problem. Contact your veterinarian or ophthalmologist when ready if you notice any of these signs.
Infection and inflammation are the most common complications, but both are treatable if caught early. Rarely, the artificial lens can shift out of position or the eye can develop glaucoma (high pressure inside the eye) after surgery. This is why follow-up visits are essential — your veterinarian checks eye pressure and lens position to catch problems before they affect vision.
Cost and what it covers
Cataract surgery in dogs typically costs between $2,500 and $4,000 per eye, though prices vary significantly by region and surgeon experience. Some specialty veterinary hospitals charge more, and rural areas may charge less. The cost usually includes the pre-surgery exam and blood work, the surgery itself, the artificial lens, anesthesia, and the first few post-operative visits. Eye drops and any additional medications are sometimes billed separately.
Pet insurance rarely covers cataract surgery because cataracts are often considered a pre-existing condition or a condition related to age. If your dog develops cataracts after you have had insurance in place, check your policy — some plans do cover surgery. Veterinary schools and some specialty hospitals offer reduced-cost surgery programs, though wait times can be longer.
Alternatives if surgery is not an option
If your dog is not a good candidate for surgery or you choose not to pursue it, your dog can still live a good life. Dogs adapt well to vision loss and rely heavily on smell and hearing. You can make your home safer by keeping furniture in the same place, using baby gates to block stairs, and keeping food and water bowls in consistent locations. A harness rather than a collar gives you better control on walks, and keeping your dog on leash in unfamiliar areas prevents accidents.
Some veterinarians prescribe eye drops containing lanosterol or other compounds marketed to slow cataract progression, though evidence for their effectiveness is limited. These drops are not a substitute for surgery and cannot reverse a cataract that is already present, but they may slow the cloudiness in the early stages. Talk with your veterinarian about whether these drops make sense for your dog's situation.
Frequently Asked Questions
At what age can dogs have cataract surgery?
Dogs of any age can have surgery if they are healthy enough for anesthesia. Senior dogs often do well, though pre-surgery blood work is especially important to check kidney and liver function. Your veterinarian will assess whether your individual dog can safely undergo anesthesia.
Will my dog's vision be completely normal after surgery?
Most dogs regain functional vision — they can navigate their home, see treats, and move around safely. Vision may not be as sharp as it was before the cataract formed, especially if the eye has other problems. Some dogs see better in bright light than dim light after surgery.
How long does it take to see improvement after cataract surgery?
Many dogs show improvement within days, though vision continues to improve over several weeks as swelling goes down and the eye heals. Full healing typically takes four to six weeks. If vision has not improved by six weeks, contact your ophthalmologist to rule out complications.
Can cataracts come back after surgery?
The original cataract cannot return because the lens has been removed. However, a new cataract can form in the other eye, or scar tissue can develop on the lens capsule (called posterior capsular opacification). This is less common in dogs than in humans but can happen.
What if only one eye has a cataract?
Surgery on one eye is still worthwhile because it restores vision in that eye and improves your dog's overall depth perception and ability to navigate. Many dogs do well with one eye treated and one eye untreated, especially if the untreated eye still has some vision.
