Cataract surgery costs around $2,500 to $4,000 per eye. Costs will vary depending on your geographic location, your pet's size, the severity of the cataract, surgical difficulty and time, and your pet's health. If a separate surgery is performed for each eye, you should expect higher overall costs due to the increased need for anesthesia and two recovery periods.Cataract surgery costs around $2,500 to $4,000 per eye.
