A Two Case of 360 Degree Keratolimbal Allograft

ABSTRACT

PURPOSE: To report the clinical outcomes of 360-degree keratolimbal allograft in 2 patients. CASE SUMMARY: An 83-year-old female who had uncontrolled Mooren's ulcer invading 360 degrees of the limbus with corneal opacity received a 360-degree keratolimbal allograft (KLAL). Another 63-year-old female who had central corneal opacity and corneal neovascularization due to severe limbal cell deficiency with chemical injury received a 360-degree KLAL. During the average 17.5 months of follow-up, both eyes were tectonically maintained without severe graft rejection. CONCLUSIONS: A 360-degree KLAL may be an effective tectonic procedure for corneal opacity caused by limbal stem cell deficiency. Herein, we report 2 cases of successfully performed 360-degree KLAL with a literature review.
