The Removal of Cataracts in Cats

Just like humans, cats can form cataracts on the eyes. Dr. Ron Hines, veterinarian and author of the 2nd Chance website, states cataracts on both eyes are a normal process of aging animals called lenticular sclerosis. If a cataract is only in one eye, then there is an underlining condition that needs to be treated.

  1. Appearance

    • According to the Cat Health website, a normal cat lens is clear and able to transmit light to the retina. A cataract will cause the lens to become cloudy, giving off an appearance of milky film over the eye. This film blocks light causing the cat to be unable to see clearly. Cataracts can start in small area of the eyes and spread.

    Causes

    • Heredity is the most common reason for cataracts. According to Dr. Ron Hines, cats can form cataracts if they were malnourished as a kitten. This mostly includes strays and kittens of strays. Another cause is injury to the circulatory system of fluids found in the eye at some point during the cat's life. Diseases such as feline leukemia and feline AIDS can also cause cataracts.

    Symptoms

    • Besides the milky film, there are other signs a cat has vision loss. Watch for hesitance. Cat Health states a cat with vision impairment due to a cataract may hesitate to climb stairs or jump off surfaces. Also keep an eye out for redness and inflammation of the eye. A cat may also squint with the affected eye.

    Removal

    • Removal of a cat's cataract is a personal decision. A cat with impaired vision can lead a normal life. But if surgery is the route you want to take, here is what to expect. Dr. John S. Sapienza, American College of Veterinary Ophthalmologists, says the surgery has a 90 percent success rate. Eye drops must be administered multiple times a day and continue until six weeks post-op. The surgery consists of removing the cataract and replacing it with a synthetic lens. The Veterinary Teaching Hospital at the University of Illinois uses ultrasonic waves to remove the lens. After surgery, an e-collar will be placed around the cat's neck to keep her from touching the eye.

    Alternatives

    • There are alternatives to surgery. While these will not remove the cataract, they can help slow the advancement. Dr. Ron Hines says many health professionals will advise giving the cat an anti-oxidant supplement such as Vitamin E and Vitamin C. Limiting your cats exposure to bright light can also help. If the cataract is caused by inflammation, a veterinarian may prescribe an antibiotic.
