A novel artificial cornea (keratoprosthesis) prototype shows promise for treating corneal blindness in dogs. Further design improvements are needed for successful clinical application in veterinary ophthalmology.

Area of Science:

  • Veterinary Ophthalmology
  • Biomaterials Science
  • Corneal Surgery

Background:

  • Corneal blindness in dogs significantly impacts vision.
  • Existing therapies for severe corneal disease are often ineffective.
  • Novel surgical solutions are needed for vision restoration.

Purpose of the Study:

  • To detail the surgical technique for a new keratoprosthesis (KP) prototype.
  • To assess the efficacy and safety of this KP in canine patients.
  • To evaluate the KP as a treatment for corneal blindness.

Main Methods:

  • A silicone KP was implanted unilaterally in seven dogs with corneal blindness.
  • The implantation involved creating a stromal pocket via deep stromal lamellar dissection.
  • Dogs had conditions like corneal endothelial disease or chronic superficial keratitis.

Surgical Technique of the 3-Dimensional-printed Personalized Hip Implant for the Treatment of Canine Hip Dysplasia

Published on: April 19, 2024

Main Results:

  • Successful KP implantation occurred in six of seven dogs.
  • Limited vision was restored in all operated eyes.
  • Complications included one intra-operative perforation and later purulent keratitis in five eyes.

Conclusions:

  • The KP prototype demonstrates potential for treating specific canine corneal diseases.
  • Improved KP design for better stromal integration is essential.
  • Further research is required before clinical approval for veterinary use.
