Summary

Two young women with completely dry and keratinised eyes post-Stevens Johnson Syndrome (SJS) underwent unilateral oral mucous membrane grafts (MMGs) in preparation for modified osteo-odonto keratoprosthesis (MOOKP) implantation. In both cases, the mucosal graft was deemed to be too tight to accommodate the MOOKP implant. Instead of proceeding with MOOKP, the first patient underwent Auro Kpro (Boston type 1-based keratoprosthesis) implantation under the MMG, while the second patient underwent implantation of a modification of Auro Kpro with a longer optical stem (LVP Kpro) exposed through the MMG. Both patients maintained a visual acuity of 20/20, N6 at 15 months post-implantation. The first patient needed repeated mucosal trimming because of mucosal overgrowth; while in the second patient, mucosal overgrowth did not occur. This report highlights the innovative and successful use of Boston type 1-based keratoprosthesis (Auro Kpro) and its modification (LVP Kpro) in completely dry and keratinised post-SJS eyes.
