Narrative Responses:

Purpose
To identify main difficulties and solutions on learning curve in Descemet’s Membrane Endothelial keratoplasty (DMEK).

Methods
A study evaluating the main difficulties and complications in the first 30 DMEK surgeries and most appropriate solutions for each complication was taken.

Results
Difficulties and solutions: preparing donor tissue(DT) / older corneas; small tears in DT / descemetorhexis curvilinear continuous; large tears in DT / release  peripheral Descemet
introduce  DT / anterior chamber depressurized; difficult to identify  endothelial side / observation peripheral Descemet folds; unfold the DT 1 / older corneas; unfold the DT 2 / open roll  2 cannulae; keep the DT unfolded / anterior chamber shallow; good adherence of the DT / air bubble in center of the cornea; Detachment of  peripherals Descemet  / observation; Detachment of Descemet affecting visual axis / rebublle.

Conclusion
Difficulties  on learning curve in Descemet’s Membrane Endothelial keratoplasty (DMEK) are best conducted using an appropriate technique.
