PURPOSE: To report two cases of coexisting keratoconus and Fuchs endothelial dystrophy treated with intrastromal corneal ring segments (ICRS) implantation and Descemet membrane endothelial keratoplasty (DMEK).
METHODS: Two patients with coexisting keratoconus and Fuchs endothelial dystrophy underwent ICRS implantation and DMEK, in a two-stage procedure. Follow-up evaluation included Scheimpflug tomography and optical coherence tomography.
RESULTS: In both cases, ICRS implantation improved corneal topography and DMEK restored normal corneal thickness. Corrected distance visual acuity improved from 20/100 to 20/30 and from 20/60 to 20/25. Urrets-Zavalía syndrome was diagnosed in one case and addressed with colored contact lens fitting.
CONCLUSIONS: Low vision resulting from coexisting keratoconus and Fuchs endothelial dystrophy might be addressed more selectively with posterior lamellar keratoplasty and ICRS implantation. Urrets-Zavalía syndrome must be considered a possible complication after DMEK, especially in patients with keratoconus. [J Refract Surg. 2020;36(10):703-706.].
