Dog cataracts can be cured. Because cataracts are irreversible ophthalmic lesions and cannot be cured by any drugs, the current treatment method for cataracts is mainly microsurgery to remove cataracts. If dogs suffering from cataracts seek medical treatment in time at the early stage or mature stage, the success rate can be as high as more than 90%. If the cataract has developed to a mature stage and there are other eye diseases, the success rate of surgery will be about 80%.

The causes of cataracts in dogs:

1. Congenital cataracts in dogs: It begins in the embryonic period. Due to abnormal development of the lens and its capsule in the mother's body, it develops immediately after birth. Manifested as inward obstruction.

2. Traumatic cataract in dogs: Due to various mechanical injuries (such as corneal penetration), the nutrition of the lens and its lens capsule is impaired.

3. Secondary cataract in dogs: secondary to other eye diseases and systemic diseases, such as iritis, uveitis, diabetes, etc.

4. Canine senile cataract: It is a degenerative change of the lens, mainly seen in dogs aged 8-12 years old.
