        • ISP placement
    • Enucleation
      • An eye is completely removed due to an ocular disease or trauma to the eye
      • The lids are cut and sewn shut and the pet looks like it is “winking”
    • ISP
      • An incision is made in the eye and the inner contents removed
      • A silicone ball is placed inside and the eye is sewn shut
    • ISP
      • ISPs are placed for cosmetics only
      • The pet has no vision as a result from the implant
      • The outside of the eye is still subject to abrasion and disease
    • Cataracts
      • The lens of one or both eyes becomes dense and the animal’s vision is restricted
      • Causes
