A preliminary study of direct application of atelocollagen into a wound lesion in the dog cornea

Purpose: To evaluate the effectiveness of atelocollagen for canine corneal wound healing. Materials and Methods: Atelocollagen was used to fill a transplant bed in the central cornea, which was then covered with a contact lens. The wound healing process was analyzed clinically, morphologically, and biochemically. Results: At the early healing stage, both the pupillary zone and details of the iris were observed. The stromal collagen fibrils normalized in a time-dependent manner. Type III collagen in the wound area was detected faintly throughout the experimental period. Conclusions: This novel method is advantageous for accelerating wound healing without causing inflammation.
