Cataracts

Vision is restored in 90-95% of patients after cataract surgery.

 

Cataracts in Dogs

Dr. Hodgson recently treated two patients for cataracts on the same day.
Over the next several weeks, we’ll follow their progress
from their initial exams, to surgery, to the follow up appointments.

1.  I should wait to have my dog’s cataracts treated until his vision is compromised.

2.  I should wait to have my diabetic dog’s cataracts treated until his diabetes is controlled/regulated.

3.  Cataracts are a disease of old age.

4.  All cataract patients have an artificial lens surgically implanted.

5.  The average age of a cataract patient is 12-13 years old.

What is a cataract?

A cataract is a change in the clear protein of the lens. Normally, the lens is transparent and clear, allowing the image that the eye is focused on to be clearly projected onto the retina. When the lens proteins change or are damaged, the lens becomes cloudy or opaque. The opaque area, or cataract, distorts the image projected onto the retina which results in a slightly blurred image. As the cataract progresses more and more of the lens is affected, which distorts the image further until vision problems occur.

Most dogs with diabetes develop cataracts within 6 to 12 months due to biochemical changes in the lens caused by elevated blood glucose levels.  Diabetic cataracts progress quickly causing blindness.  Surgical removal of the cataract restores vision and improves quality of life.  Removal of the cataract by phacoemulsification surgery is still the only present method of improving or restoring vision in a patient with cataracts.
