Deep lamellar endothelial keratoplasty in 10 horses.
Abstract: To describe and evaluate a surgical technique utilized for the therapy of deep corneal stromal abscesses (DSA) in horses. The DSA is excised and replaced with a partial thickness corneal lamellar allograft. Methods: A retrospective clinical study describing the indications for the surgical technique utilized and the outcomes of this procedure in 10 eyes of 10 horses. Results: Each affected eye had a discrete DSA within the posterior stroma. An initial partial thickness semicircular corneal incision was made at the limbus, followed by anterior stromal lamellar dissection over the lesion. After excision of the DSA and replacement with a larger diameter split-thickness donor button, the anterior stroma was replaced into its original position and the initial corneal incision was repaired. All of the animals that underwent deep lamellar endothelial keratoplasty (DLEK) procedure healed appropriately and with subjectively less postoperative scarring and complications than previously described surgical approaches to DSA. Conclusions: This procedure is an effective technique for surgical removal of DSA in horses and, in most cases, results in a visual and cosmetically acceptable globe. The advantages of this technique compared to other surgical approaches to DSA are the peripheral location of the incision, shortened anesthesia times, the resultant minimal scarring and shorter healing times associated with DLEK.

The research article discusses a surgical procedure called deep lamellar endothelial keratoplasty (DLEK) used to treat deep corneal stromal abscesses (DSA) in horses, and evaluates its effectiveness. The authors highlight the advantages of DLEK, which include less scarring, a quicker recovery time, and improved visual and cosmetic outcomes.
Methodology and Procedure
The study applies a retrospective approach to discuss the reasons for using this surgical technique and assess its outcomes in ten different horses. Each participating horse presented a distinct DSA located within their posterior stroma.
- Surgeons initiated the procedure by carving out a partial-thickness semicircular corneal incision at the limbus.
- Next, doctors performed an anterior stromal lamellar dissection over the abscessed area.
- Following the surgical removal of the DSA, the void was filled with a larger-diameter split-thickness donor button.
- The anterior stroma was carefully returned to its initial place and the primary corneal incision was mended.
Results and Observations
Throughout their recovery period, all horses that had undergone DLEK healed as expected. Importantly, the researchers reported a subjective decrease in postoperative scarring and complications compared to previously documented surgical treatments for DSA.
Conclusions and Implications
The research team concluded that DLEK acts as an effective surgical remedy for DSA in horses. Most of the cases resulted in a visually and cosmetically satisfactory globe. Compared to alternative surgical procedures for the same condition, DLEK displayed several advantages:
- The incision was typically made at the periphery, thereby causing less disruption to the animal.
- The procedure shortened anesthesia times which can reduce the chances of adverse reactions to anesthesia.
- There was minimal scarring detected, enhancing the cosmetic result and reducing the possibility of vision interference.
- Healing period post-surgery was shorter, sparking faster recovery for the horses.
