Pet Cataracts in Rocklin, CA

Cataracts are cloudings of the lens in one or both eyes that cause vision impairment or loss. It is most common in diabetic patients and those that have had uveitis (inflammation) inside the eye(s), although it can be caused by genetics, trauma, or old age. Surgery or medication may be used to treat the condition.

What is a cataract?

Currently, no medical treatment is available to slow or prevent the formation of cataracts. Cataracts can cause severe inflammation in the eye. Treatment with anti-inflammatory drops will help prevent secondary glaucoma and improve the successful outcome of cataract surgery. If your pet has cataracts and its eyes are bloodshot, you need to start therapy immediately, regardless of whether you want to pursue surgery to remove cataracts. Surgical removal of cataracts is the only treatment available to restore vision.

Is my pet a candidate for cataract surgery?

All pets with cataracts should have an evaluation with a Veterinary Ophthalmologist. Diagnostic tests will be performed to determine the cause of the cataracts. The longer the cataract has been present in the eye, the more inflammatory damage it can cause. Prompt referral to a Veterinary Ophthalmologist when a cataract is diagnosed is recommended even if you do not want to pursue cataract surgery for your pet. Glaucoma, or increased pressure in the eye, is a common complication when a cataract is present for an extended period of time. Medical therapy can alleviate pain and inflammation in the eye and lessen the need for the removal of the blind eye.

IMMEDIATE referral for patients considering cataract removal will hasten treatment and increase the success rate of the cataract surgery. Examination of patients before cataracts cause complete vision loss results in a better surgical outcome. All diabetic patients should have an ophthalmic examination as soon as the diabetes is diagnosed. Diabetic cataracts can advance rapidly and cause severe inflammation in the eye. Before undergoing cataract surgery, your pet will have a complete ophthalmic examination and a series of tests to determine if it is a good candidate for surgery. These diagnostic tests include intraocular pressure readings, gonioscopic and ultrasonic examinations, an electroretinogram (ERG), blood pressure measurement, and complete blood analysis. These tests are performed within two to three weeks of the scheduled surgery date to determine if your pet is a good candidate for cataract removal.

How is cataract surgery performed and what is the aftercare?

Cataracts are removed in most cases by phacoemulsification surgery. This involves the ultrasonic breakdown of the lens material and its aspiration out of the eye. If the lens capsule is stable, an intraocular lens (IOL) will be implanted in the eye to improve immediate post-operative and near vision. The decision to insert an IOL is at the discretion of the surgeon. The surgery is performed with the patient positioned under an operating microscope using delicate instruments and state-of-the-art phacoemulsification equipment. The patients are monitored closely under anesthesia by a veterinary technician. The surgery takes 60 to 90 minutes per eye. Patients go home on the day of surgery and are re-evaluated the next morning. They will wear an Elizabethan collar for 10 to 14 days to prevent them from rubbing or bumping their eyes. Patients require medication with eye drops four to six times daily as well as oral medications once to twice daily. Frequent re-examinations are required for the first three weeks, then every three months for the first year, followed by yearly rechecks. Strict patient compliance concerning post-operative therapy and re-examination is imperative for the long-term maintenance of vision. Cataract removal surgery is a highly successful procedure. However, complications, including retinal detachment, chronic inflammation, glaucoma, intraocular bleeding, and vision loss, can occur.
