Lamellar corneal transplantation in the horse.

This is a study on lamellar keratoplasty (corneal transplantation) in horses. The research finds that this methodology could be a viable tool for repairing corneal defects in horses with the potential to restore vision.

Methodology

In this research, fourteen transplantations were conducted on the equine eye using a modified trephine, an instrument used for cutting circular pieces, with an adjustable inside guard. This allowed for identical discs to be taken from the donor and the recipient’s cornea. The transplantations performed were split into two experimental groups:

• Seven were homografts which involved grafting tissue from a donor to a recipient of the same species.
• The other seven were heterografts with grafting taking place between two individuals of two different species.
• These transplants were 15mm and 9mm in diameter, respectively.

Importance of Wound Margins

The study emphasized that for successful transplantation and healing, it is imperative to have sharp-edged, vertical, and regularly outlined wound margins on both the donor graft and the recipient site. This ensures good adaptation and healing without tension.

Process Details

The study also elaborately explains the preparation for operation, the surgical technique used, and the necessary postoperative care. These processes are crucial to fully understanding and replicating the research for further study and application.

Result Indication

Based on the experiments conducted, the results indicated that the method of lamellar corneal transplantation could be a feasible tool for repairing corneal defects in horses. This has potential applications in restoring vision and hence enhances the wellbeing of the horse. Using this methodology could contribute significantly to animal health and veterinary medicine, and present a solution for corneal opacities in equine eyes, which has been rarely documented until now.
