Purpose

To study the Scheimpflug tomography changes before and after surgery in patients undergoing endothelial keratoplasty for Fuchs endothelial corneal dystrophy (FECD).

Setting

Retrospective, observational study done at a tertiary care centre in India. Patients who underwent Descemet strippping automated endothelial keratoplasty for fuchs endothelial dystrophy were included in the study.

Methods

Ten eyes of 10 patients with grade 4 FECD (Amsler Krumeich classification system) who underwent endothelial keratoplasty (EK) were included in the study. Scheimpflug imaging was done in all eyes and the maps were assessed pre-EK for tomographic features suggestive of FECD. Imaging was repeated post-EK to look for changes in the tomographic features. Both images were assessed by two masked observers for topographical changes.

Results

Pre-EK, all eyes showed loss of regular isopachs, displacement of the thinnest corneal point and posterior surface depression on tomography. Post EK, there was regularization of isopachs, shifting back of the thinnest corneal point and decrease or disappearance of posterior corneal depression in all the eyes. One eye which developed graft failure secondary to rejection developed a reversal of these changes signifying the potential benefit of the role of Scheimpflug in detecting early graft failure.

Conclusions

Scheimpflug tomography changes occur in eyes with FECD and these changes reverse after a successful EK. The Scheimpflug could be used to monitor the disease and could potentially be useful in detecting failing grafts.
