The most common cause of cataracts in dogs and cats is an inherited defect in the lens. In addition, cataracts may develop following an eye injury, inflammation in the eye or a systemic disease such as diabetes. Cataract removal is a very delicate surgical procedure. A complete examination of the eyes is necessary to determine if a pet is a good surgical candidate, Typically an electroretinogram (ERG) is required to test retinal function of the eye, as well as an ocular ultrasound. Also important is the pet's general health. A blood sample is submitted prior to surgery to be sure the pet's internal organs are functioning normally. This lab work may be performed at your regular veterinarian's office. Surgery is usually performed in the morning and pets are discharged the same afternoon. Following surgery medications and complete instructions will be sent home with the pet. Follow up visits are important to monitor the healing process. Most patients are seen regularly for a few months following surgery, then yearly rechecks are advised. The pet typically will regain vision as healing in the eye takes place.
