Purpose
Show the results obtained during the DSAEK learning curve.
Setting
The surgery for selective corneal endothelial transplantation is a procedure that requires specific specialized knowledge. It is a conceptually standardized surgery. Until the necessary skill level for the procedure is acquired, success rates may be lower. However, with meticulous surgical practice, favorable outcomes can be expected from the outset. Its reliance on donor tissue implies that despite meticulous and successful surgical execution ("no touch technique"), primary failures may occur.
Methods
Evaluation of the anatomical and functional success rates of the first 50 cases of ultrathin DSAEK.
Underlying pathologies will be evaluated for indication, as well as the phakic or pseudophakic ocualr status, other possible previous surgeries, pre- and post-operative comparisons of visual acuity, pachymetry, etc.
Also the method of graft insertion will also be evaluated, either by the Busin technique or using the Endoserter device. As well as the method of tamponade, either with air or with 20% SF6 gas.
Results
Still pending analysis. They will be presented on the poster (mainly through tables)

Conclusions
DSAEK surgery is proven to be safe and effective in restoring corneal endothelial function.
The advantages of selective transplantation compared to penetrating transplantation include decreased surgical risk, reduced comorbidities, as well as a marked improvement in refractive outcomes.
The endothelial cell count of the donor cornea, provided by the tissue bank, is a measure previous to the microkeratome cut with the necessary hyperpressurization of the sclerocorneal button in an artificial anterior chamber (something that is not performed in DMEK). This process, however, could potentially damage the endothelium and thus justify some primary failures despite uneventful surgery.
