Abstract Details


To evaluate refractive change and stability at two years after Descemet membrane endothelial keratoplasty (DMEK).


Retrospective study at a tertiary referral center.


149 DMEK eyes with complete follow-up data up to two years were reviewed, complete subjective refractive and Pentacam data were obtained.


A mean hyperopic shift in spherical equivalent of about +0.4D, and a mean change in refractive cylinder of ±-0.3D were found at 3 months postoperatively. No significant change was observed up to two years. Pentacam showed a mean decrease in true net power of ±1D.


There may be a minimal refractive change and stabilization 3 months after DMEK. Refraction remained stable up to 2 years after DMEK. The hyperopic shift may result from stromal deswelling. FINANCIAL INTEREST: NONE
