A New Model of Temporary Intraoperative Keratoprosthesis

Relevance. Pen globe injury (OGI) is one of the most severe types of ocular trauma in both peacetime and wartime conditions. Considering the extent of damage to the anterior and posterior segments of the eye and the need for simultaneous vitreoretinal surgery, temporary keratoprosthesis is required in 47.1% of cases. Objective. To develop a Russian analog of a temporary keratoprosthesis for combined vitreoretinal and optic-reconstructive surgery. Materials and Methods. The main technical requirements were formulated. A model of a temporary intraoperative keratoprosthesis was developed. Results and Discussion. The properties of K-8 optical glass suggest a high potential for the intraoperative temporary keratoprosthesis made from this material. Conclusion. The proposed temporary intraoperative keratoprosthesis enables vitreoretinal and optic-reconstructive treatment of severe ocular trauma and serves as a viable alternative to foreign analogs. Keywords: Temporary keratoprosthesis, open globe injury, optic-reconstructive surgery.
