Cataracts in cats: signs, treatment options, & surgery cost
$2,000 – $4,000 per eye
$3,000 – $8,000 both eyes
$300 – $800 pre-surgical diagnostics
How much does cat cataract surgery cost?
Cat cataract surgery costs $2,000 to $8,000 depending on whether one or both eyes need treatment, the severity of the condition, your geographic location, and the veterinary ophthalmologist performing the procedure. For a single eye, expect to pay $2,000 to $4,000. Bilateral surgery on both eyes typically runs $3,000 to $8,000.
| Procedure | Average Cost |
|---|---|
| Cataract surgery (one eye) | $2,000 – $4,000 |
| Cataract surgery (both eyes) | $3,000 – $8,000 |
| Pre-surgical diagnostics (bloodwork, ultrasound, ERG) | $300 – $800 |
| Post-operative medications (eye drops, anti-inflammatories) | $50 – $200 |
| Follow-up veterinary visits | $50 – $150 per visit |
Cataract surgery on cats is almost always performed by a board-certified veterinary ophthalmologist, which accounts for the higher price point compared to general veterinary procedures. The total bill usually includes the initial consultation, anesthesia, operating room time, the surgical procedure itself, hospitalization, and take-home medications.
Geography also plays a significant role in pricing. Pet parents in major metropolitan areas and coastal cities tend to pay closer to the upper end of the range, while those in rural areas or the Midwest may see lower costs.
If cost is a concern, ask your veterinary ophthalmologist about payment plans or financing options through services like CareCredit. Some veterinary schools with ophthalmology programs also offer reduced-cost procedures performed by supervised residents.
What are cataracts in cats?
A cataract is an opacity or cloudiness that develops in the lens of a cat's eye, interfering with the normal passage of light and reducing vision. The lens is a small, transparent, disc-shaped structure located just behind the iris. In a healthy eye, it focuses incoming light onto the retina, which then transmits visual information to the brain through the optic nerve.
When a cataract forms, the lens becomes cloudy or completely opaque, blocking light from reaching the retina. Depending on the size and stage of the cataract, a cat may experience anything from subtle visual changes to total blindness.
| Cataract Stage | Description | Vision Impact |
|---|---|---|
| Incipient | Small, focal opacity covering less than 15% of the lens | Minimal to no vision loss |
| Immature | Partial cloudiness affecting a larger portion of the lens | Mild to moderate vision impairment |
| Mature | Entire lens is opaque | Significant to complete vision loss |
| Hypermature | Lens proteins begin to break down and leak | Blindness with potential secondary complications |
Cataracts can develop in one or both eyes and are more common in senior cats over the age of 10, though they can occur at any age. Left untreated, advanced cataracts can lead to secondary complications like glaucoma or chronic inflammation (uveitis), which may eventually necessitate removal of the eye.
Signs and symptoms of cataracts in cats
The earliest signs of cataracts in cats are often behavioral rather than visible. Because cats are naturally stoic and skilled at compensating for gradual vision loss, subtle changes in behavior may be the only clue that something is wrong with their eyes.
| Symptom Type | What to Look For |
|---|---|
| Visual changes in the eye | Pearl-like sheen, cloudy or hazy blue-white appearance in one or both eyes |
| Navigation difficulties | Bumping into furniture, hesitation before jumping, avoiding stairs |
| Behavioral shifts | Increased vocalization, disorientation (especially in dim lighting), reluctance to explore unfamiliar areas |
| Daily routine disruption | Difficulty finding food bowls, water dishes, or the litter box |
| Reduced activity | Less playfulness, decreased agility, general reluctance to move around |
Early signs
In the initial stages, you may notice a subtle pearl-like sheen across the surface of your cat's eye that does not wipe away. Your cat might seem slightly confused in dimly lit rooms, vocalize more than usual, or hesitate before making jumps they once completed with ease.
Advanced signs
As cataracts progress, the cloudiness becomes clearly visible, often appearing as a blue-white or milky haze over one or both eyes. Cats at this stage frequently bump into furniture, struggle to locate their food and water, and show reluctance to move through unfamiliar environments. Some cats may also develop eye redness, excessive tearing, or squinting if inflammation accompanies the cataract.
Not all cloudy eyes indicate cataracts. A condition called nuclear sclerosis causes a similar hazy appearance in aging cats but does not affect vision. Only a veterinarian can distinguish between the two, so schedule an exam if you notice any changes in your cat's eyes.
Causes of cataracts in cats
Unlike in dogs, where genetics and diabetes are the leading causes, cataracts in cats most commonly result from chronic eye inflammation (uveitis) or trauma. Understanding the underlying cause is essential because it determines whether the cataract will progress and whether surgery is a viable option.
| Cause | Details |
|---|---|
| Chronic uveitis | The most common cause; ongoing inflammation inside the eye damages the lens over time |
| Eye trauma | Injuries such as corneal ulcers or penetrating wounds can trigger cataract formation |
| Congenital/hereditary | Some cats are born with cataracts or develop them due to inherited genetic defects |
| Infectious diseases | Feline leukemia (FeLV), feline immunodeficiency virus (FIV), feline infectious peritonitis (FIP), and Toxoplasma gondii |
| Aging | Lens degeneration occurs naturally in cats over 10 years old |
| Nutritional deficiencies | Inadequate diet in kittens can cause early cataract development |
| Diabetes and hypertension | Rare in cats compared to dogs, but metabolic disorders can contribute |
| Radiation therapy | Radiation treatment to the head or face can damage the lens |
| Toxic exposure | Certain drugs, chemicals, or even electric shock may trigger cataracts |
Breeds predisposed to cataracts
While any cat can develop cataracts, certain breeds carry a higher genetic risk. These include:
- Persian
- Birman
- Siamese
- Russian Blue
- Himalayan
- Burmese
If you own one of these breeds, regular veterinary eye exams become especially important as your cat ages. Early detection allows for more treatment options and better outcomes.
How veterinarians diagnose cataracts
Diagnosis begins with a thorough ophthalmic examination. Your veterinarian will use an ophthalmoscope to inspect the lens inside each eye, typically in a darkened room after dilating the pupils for a clear view.
| Diagnostic Test | Purpose |
|---|---|
| Ophthalmoscopic exam | Visualizes the lens to identify cataracts and distinguish them from nuclear sclerosis |
| Slit-lamp biomicroscopy | Provides a magnified, detailed view of the lens structure |
| Ocular ultrasound | Evaluates structures behind the lens, including the retina |
| Electroretinography (ERG) | Tests retinal function to confirm the eye can process light after cataract removal |
| Blood work and urinalysis | Screens for underlying conditions like diabetes, infections, or organ dysfunction |
| Blood pressure measurement | Checks for hypertension, which can contribute to eye disease |
Once cataracts are confirmed, your vet will likely recommend additional testing to identify the underlying cause. Blood work, urinalysis, and blood pressure measurements help screen for systemic diseases such as diabetes, feline leukemia, FIV, or hypertension.
If surgery is being considered, a referral to a veterinary ophthalmologist is the next step. The specialist will perform advanced testing, including an ocular ultrasound to examine the structures behind the cloudy lens and an electroretinogram (ERG) to verify that the retina is functioning properly. A healthy retina is critical for successful surgical outcomes.
Treatment options for cataracts in cats
Surgery is the only treatment that can restore vision lost to cataracts. However, not every cat is a suitable surgical candidate, and several non-surgical approaches can help manage the condition and maintain quality of life.
| Treatment | Goal | Estimated Cost |
|---|---|---|
| Cataract surgery (phacoemulsification) | Removes the cloudy lens and restores vision | $2,000 – $8,000 |
| Anti-inflammatory eye drops | Reduces inflammation and slows progression | $20 – $80 per month |
| Steroid eye drops | Controls uveitis associated with cataracts | $20 – $60 per month |
| Antioxidant supplements (e.g., Ocu-GLO) | Supports lens health and may slow degeneration | $25 – $50 per month |
| Treatment of underlying disease | Addresses root causes like hypertension or infection | Varies |
Medication and supportive care
While no medication can reverse or remove a cataract, anti-inflammatory and steroid eye drops can reduce painful swelling inside the eye and may slow progression. Your veterinarian might also recommend antioxidant supplements designed for eye health, which support the lens and surrounding tissues.
When cataracts are caused by an underlying condition like high blood pressure or an infectious disease, treating that condition can sometimes slow further cataract development.
When is surgery recommended?
Veterinary ophthalmologists typically recommend surgery when cataracts are causing significant vision loss, are actively progressing, or are threatening the overall health of the eye through secondary inflammation or glaucoma. The best surgical outcomes occur when cataracts are addressed relatively early, before they become hypermature and begin leaking lens proteins that trigger further inflammation.
What happens during cataract surgery
Cataract surgery in cats uses a technique called phacoemulsification, the same method used in human cataract procedures. The surgery is performed under general anesthesia by a board-certified veterinary ophthalmologist and typically takes about one hour per eye.
| Surgical Step | Description |
|---|---|
| Pre-surgical preparation | Blood work, ocular ultrasound, and ERG testing to confirm the cat is a good candidate |
| General anesthesia | The cat is fully anesthetized and monitored throughout the procedure |
| Corneal incision | A small incision is made in the cornea to access the lens |
| Phacoemulsification | A high-frequency ultrasonic instrument breaks the cloudy lens into tiny fragments for removal |
| Artificial lens placement | A prosthetic intraocular lens (IOL) is inserted into the lens capsule |
| Incision closure | The corneal incision is sutured shut |
If both eyes have operable cataracts, most ophthalmologists recommend performing surgery on both during the same session. This approach means the cat only needs one round of anesthesia and one recovery period, which is generally easier on the animal.
Success rate
Cataract surgery in cats carries an approximately 90% success rate, meaning nine out of ten operated eyes achieve a favorable outcome. Success rates are higher when cataracts are relatively recent rather than months or years old. Cats with concurrent eye conditions like uveitis, glaucoma, or retinal degeneration face higher surgical risks and may have lower success rates.
Risks and complications
As with any surgical procedure, complications are possible. The most common issues include:
- Post-operative inflammation (uveitis)
- Lens fiber regrowth (posterior capsule opacification)
- Post-operative high eye pressure (ocular hypertension)
- Glaucoma
- Retinal detachment
The most frequently seen complications, inflammation and lens fiber regrowth, are generally manageable with medication. Glaucoma and retinal detachment are more serious but occur less often. Long-term monitoring by your ophthalmologist is essential because complications can develop weeks, months, or even years after surgery.
Recovery after cataract surgery
Most cats are discharged within 24 hours of surgery. Full recovery typically takes four to six weeks, during which careful at-home care is essential to protect the surgical site and support healing.
| Recovery Phase | Timeline | Key Actions |
|---|---|---|
| Immediate post-op | First 24 to 48 hours | Rest, Elizabethan collar (cone), limited activity |
| Early recovery | Weeks 1 to 2 | Multiple daily eye drop applications, monitoring for redness or swelling |
| Mid recovery | Weeks 3 to 4 | Gradual reduction of eye drop frequency, follow-up visit with ophthalmologist |
| Long-term maintenance | Ongoing | Daily eye drops (often for life), annual ophthalmology check-ups |
Your cat will need to wear an Elizabethan collar to prevent scratching or rubbing the eyes during healing. Topical eye medications, including anti-inflammatory and antibiotic drops, are typically administered multiple times per day for the first several weeks and then gradually tapered.
Many veterinary ophthalmologists recommend lifelong daily eye drops to maintain ocular health after surgery. Follow-up exams should occur at least once every 9 to 12 months to monitor for late-onset complications.
Keep your cat in a calm, quiet environment during recovery. Avoid roughhousing with other pets and limit jumping by providing easy access to food, water, and the litter box at floor level.
Does pet insurance cover cataract surgery?
Yes, most accident-and-illness pet insurance policies cover cataract surgery, provided the condition is not classified as a pre-existing condition. Depending on your policy's terms, you could be reimbursed for up to 80% to 100% of the surgical bill after your deductible is met.
| Insurance Factor | Details |
|---|---|
| Typical coverage | Accident and illness plans generally cover cataract surgery |
| Pre-existing condition exclusion | Cataracts diagnosed before the policy start date are not covered |
| Reimbursement rate | 70% – 100% depending on the plan |
| Waiting period | Most plans have a 14- to 30-day waiting period for illness coverage |
The key takeaway is timing. To ensure coverage, enroll your cat in pet insurance while they are young and healthy, well before any eye problems develop. This is particularly important for breeds genetically predisposed to cataracts, such as Persians, Siamese, and Himalayans.
Before purchasing a policy, review the fine print for details on annual coverage limits, deductibles, and any breed-specific exclusions that might apply.
Living with a cat that has cataracts
Not every cat with cataracts is a good candidate for surgery. Older cats with significant health issues, cats with concurrent eye diseases, or pet parents who cannot afford the procedure can still help their feline companion live a comfortable life with reduced or absent vision.
| Home Modification | How It Helps |
|---|---|
| Keep furniture in consistent positions | Allows the cat to memorize pathways and navigate by memory |
| Use baby gates near stairs | Prevents dangerous falls |
| Place food, water, and litter in the same spots | Reduces confusion and anxiety |
| Avoid rearranging rooms | Cats rely on spatial memory to compensate for vision loss |
| Add nightlights | Provides minimal light to help cats with partial vision |
| Speak to your cat before approaching | Prevents startling and builds trust |
Cats are remarkably adaptable animals. They rely heavily on their whiskers, hearing, and sense of smell to navigate their surroundings. Many cats with cataracts continue to eat well, use the litter box without issues, and enjoy affection from their families.
Even without surgery, routine veterinary monitoring remains important. Your vet can prescribe anti-inflammatory eye drops to manage discomfort and watch for secondary complications like glaucoma, which could cause pain and require additional intervention.
Frequently asked questions
Are cataracts common in cats?
Cataracts are less common in cats than in dogs. When they do occur, they are most frequently seen in senior cats over the age of 10 or in cats with chronic eye inflammation, infectious diseases, or a history of eye trauma.
Can cats go blind from cataracts?
Yes. Small, incipient cataracts may cause only minor vision changes, but mature and hypermature cataracts can block light from reaching the retina entirely, resulting in complete blindness in the affected eye.
Can cataracts be reversed without surgery?
No. There is currently no medication, eye drop, or supplement that can dissolve or reverse a cataract. Medications can help manage inflammation and potentially slow progression, but surgery is the only way to restore vision.
Is my older cat too old for cataract surgery?
Age alone does not automatically disqualify a cat from surgery. The decision depends on overall health, the severity of the cataract, and whether the retina is functional. Pre-surgical blood work and diagnostic testing help the veterinary ophthalmologist determine if your cat can safely undergo anesthesia and the procedure.
Should both eyes be operated on at the same time?
Most veterinary ophthalmologists recommend bilateral surgery when both eyes have operable cataracts. Performing both procedures in a single session requires only one anesthesia event and one recovery period, which is generally easier on the cat.
What is the difference between cataracts and nuclear sclerosis?
Nuclear sclerosis is a normal age-related change where the lens becomes slightly hazy or bluish in appearance. Unlike cataracts, nuclear sclerosis does not significantly impair vision and does not require treatment. A veterinarian can differentiate between the two conditions during an ophthalmic exam.
Can cataracts in cats be prevented?
There is no guaranteed way to prevent cataracts, but you can reduce risk factors. Keep your cat's vaccinations current to protect against infections like FeLV and FIV. Feed a balanced, high-quality diet. Schedule regular veterinary check-ups, especially as your cat ages. For predisposed breeds, consider annual eye exams starting in middle age.
