Understanding Cataracts in Cats
Cataracts in cats are a condition characterized by the clouding of the lens of the eye. This clouding can result in impaired vision and, if left untreated, can lead to significant vision loss. Understanding the causes, predisposition, symptoms, and diagnosis of cataracts in cats is crucial for timely intervention and appropriate treatment.
Causes and Predisposition
Cataracts can occur in cats of any age, sex, or breed. However, certain breeds, such as Himalayans, Birmans, and British Shorthairs, have a genetic predisposition to inherited cataracts. Inflammation within the eye, known as uveitis, is the most common cause of cataracts in cats. Uveitis can result from various underlying disease processes, leading to the development of cataracts.
Symptoms and Diagnosis
Detecting cataracts in cats can be challenging, as they may not exhibit obvious symptoms in the early stages. However, as the condition progresses, the cat may show signs of vision impairment. These signs can include hazy eyes in certain light conditions and difficulty in navigating the surroundings (VCA Hospitals). Some common signs of cataracts in cats include:
- Cloudy or opaque appearance of the eye
- Changes in eye color
- Decreased or altered vision
- Bumping into objects or furniture
- Increased sensitivity to light
If you notice any of these signs, it’s important to consult a veterinarian for a proper diagnosis. Cataracts in cats are diagnosed through an ophthalmic exam using a special instrument called an ophthalmoscope. This allows the veterinarian to assess the internal structures of the eye and identify any abnormal opacities within or on the surface of the lens, indicating the presence of cataracts (VCA Hospitals).
Early detection and diagnosis of cataracts in cats are essential to determine the appropriate treatment options and prevent further vision loss. In the following sections, we will explore the available treatment options for cat cataracts, as well as preventive measures and management strategies.
Treatment Options for Cat Cataracts
When it comes to treating cat cataracts, surgical intervention is considered the ideal and most effective option. It is crucial to consult a veterinary ophthalmologist to ensure the best outcome for your feline companion. The treatment process involves two main components: surgical intervention and post-surgery care.
Surgical Intervention
Cat cataract surgery, specifically phacoemulsification, is performed by a veterinary ophthalmologist. This procedure involves breaking down and removing the cataract from the lens of the eye. The cataract is replaced with an artificial lens, also known as a prosthetic lens. This lens helps to restore vision and clarity in the affected eye(s) (VCA Hospitals).
The surgery itself requires specialized equipment and expertise. The veterinary ophthalmologist will administer anesthesia to ensure the comfort of the cat during the procedure. The cataract is carefully removed, and the prosthetic lens is implanted in its place. This surgical intervention aims to improve your cat’s vision and overall quality of life.
Post-Surgery Care
Following cat cataract surgery, proper post-surgery care is essential for a successful recovery. It is crucial to strictly adhere to the post-surgery care instructions provided by the veterinary ophthalmologist. These instructions may vary based on the specific needs of your cat, but commonly include the following:
-
Topical Eye Medicine: Your veterinarian will prescribe specific eye drops or ointments to be applied to the eyes. These medications help prevent infection and promote healing. It is important to administer these medications as directed and complete the full course of treatment.
-
Confinement and Restricted Activity: To prevent complications such as swelling and bleeding, it is important to keep your cat in a confined space for at least three weeks post-surgery. This confinement helps minimize excessive movement and allows for proper healing and recovery. Consult your veterinarian for specific instructions regarding confinement and restricted activity.
By following these post-surgery care guidelines, you can help ensure a smooth recovery for your cat after cataract surgery. Regular follow-up appointments with the veterinary ophthalmologist will also be necessary to monitor your cat’s progress and address any concerns that may arise.
Remember, the success of cat cataract surgery and the overall outcome depend on various factors, including the specific condition of your cat’s eyes and their overall health. It is important to consult with a veterinary ophthalmologist to determine if your cat is a suitable candidate for surgery and to receive personalized guidance throughout the treatment process.
Preventing and Managing Cat Cataracts
When it comes to cataracts in cats, prevention and management are key. While some factors leading to cataract development may be out of our control, there are measures that can be taken to support eye health and potentially reduce the risk of cataracts. Nutritional considerations and the role of amino acids are particularly important in this regard.
Nutritional Considerations
Proper nutrition plays a crucial role in reducing the risk of feline cataracts. A well-balanced diet that caters to the specific life stage of your cat can provide essential nutrients to support eye health. Antioxidant vitamins, such as vitamin C, lutein, and B vitamins, along with omega-3 fatty acids, have been associated with maintaining healthy eyes in cats (Hill’s Pet Nutrition).
To ensure your cat receives the necessary nutrients for eye health, consider feeding them a high-quality cat food that is formulated to meet their specific nutritional needs. These specially formulated foods often contain the appropriate balance of vitamins, minerals, and antioxidants to support overall eye health and potentially reduce the risk of cataracts.
Amino Acids and Eye Health
Amino acids are the building blocks of proteins and play a vital role in eye development in cats. Adequate intake of amino acids can help reduce the risk of cataracts and support overall eye health. Including protein sources that provide a complete amino acid profile in your cat’s diet is essential for their eye health.
While proper nutrition, including amino acids, is important for reducing the risk of cataracts, it’s crucial to consult with your veterinarian to ensure your cat’s specific dietary needs are met. Your veterinarian can recommend the appropriate diet and nutritional supplements, if necessary, to support your cat’s overall health and eye health.
By focusing on proper nutrition and providing your cat with a well-balanced diet, you can help promote healthy eyes and potentially reduce the risk of cataracts. Remember to consult with your veterinarian to determine the best nutritional approach for your cat’s individual needs.

Success Rates and Complications
When considering cat cataract surgery as a treatment option, it’s important to understand the success rates and potential complications associated with the procedure. Surgical intervention can provide significant improvement in a cat’s vision, but it’s essential to be aware of the possible outcomes.
Surgical Success Rates
Studies have shown that the overall visual success rate of cats after phacoemulsification, a common surgical technique for cataract removal, is high. According to a study published on PubMed, the visual success rate of cats with a 12-month follow-up after phacoemulsification was 92.6%. Out of 27 eyes, 25 showed success in terms of visual improvement.
Potential Complications
While cat cataract surgery generally has a high success rate, it’s important to be aware of potential complications that can arise. According to the same study mentioned above, the most common complications immediately after surgery were postoperative ocular hypertension (POH) and uveitis. POH occurred in 42.6% of eyes, while uveitis was the most common complication.
In the long-term, complications such as posterior capsular opacity (PCO), synechia/dyscoria, and corneal ulceration can occur. PCO occurred in 36.1% of eyes at more than 90 days postoperatively, while corneal ulceration was reported in 26.8% of cats immediately after surgery, decreasing to 12.7% in the more than 90 days postoperative period.
It’s worth noting that glaucoma, a common complication in dogs following cataract surgery, is not frequently observed in cats. The prevalence of glaucoma in cats undergoing cataract surgery is low compared to dogs. However, monitoring the eyes post-surgery is crucial, as complications can arise even years after the surgery. Regular check-ups with a veterinarian specializing in ophthalmology are recommended for ongoing eye health evaluation.
Understanding the potential complications and closely monitoring your cat’s eyes post-surgery can help ensure the best possible outcome. If you notice any changes in your cat’s vision or behavior following cataract surgery, it’s important to consult with your veterinarian promptly.

Comparative Insights from Vet Studies
When considering cat cataract surgery, it’s important to understand the various factors that can impact the procedure’s success and outcomes. Veterinary studies have provided valuable insights into age considerations and the suitability of diabetic cats for cataract surgery.
Age Considerations
Contrary to popular belief, age alone is not a deterrent to cataract surgery in cats. In fact, cataract surgery has been successfully performed on cats as old as 19 years (Animal Eye Care). However, it’s important to note that older cats may have age-related retinal degeneration, which can affect vision post-surgery. This potential vision impairment should be thoroughly evaluated by a veterinarian to ensure realistic expectations for the cat’s postoperative vision.
Diabetic Cats and Cataract Surgery
Diabetic cats, despite their underlying health condition, can still be excellent candidates for cataract removal. The increased sugar levels in their lenses often make the cataracts softer and easier to remove using techniques like phacofragmentation (Animal Eye Care). However, it’s important to consider that diabetic patients may have slower wound healing and a higher risk of infection. To manage these risks, additional sutures may be used during surgery, and postoperative antibiotic tablets may be prescribed.
It’s crucial to consult with a veterinarian experienced in feline ophthalmology to determine the suitability of cataract surgery for a diabetic cat. The veterinarian will assess the overall health of the cat, including the management of diabetes, before proceeding with the surgery. Regular monitoring and follow-up care are essential to ensure the cat’s well-being during the recovery process.
By understanding the comparative insights from vet studies, cat owners can make informed decisions regarding cat cataract surgery. Age considerations should be evaluated on an individual basis, considering any age-related retinal degeneration. Diabetic cats can still undergo cataract surgery, but extra precautions should be taken to ensure proper wound healing and prevent infections. Consultation with a veterinarian specializing in feline ophthalmology will provide the necessary guidance and support throughout the entire process.
