Abstract Details


Endothelial keratoplasty is currently the gold-standard in Fuchs disease/Bullous keratopathy surgical treatment. Descemet stripping automated endothelial keratoplasty (DSAEK) is technically demanding with a challenging learning curve. The exchange of knowledge and experience between surgeons is essential, especially in the beginnings of any procedure. The purpose of our study is to compare the learning curve of pioneer surgeons in the DSAEK technique in Centro Hospital Lisboa Central (CHLC) and the generation of surgeons that followed.


Centro Hospitalar Lisboa Central


Retrospective study of data of patients submitted to DSAEK between 2009 and 2014 at CHLC. The ten first cases of 2 surgeons that were pioneers of the technique in our center (Group 1) and ten first cases of 2 surgeons whose learning curve was supervised by experienced surgeons in the technique were selected. Demographic data, surgical indications, visual acuity evolution and complications were analyzed.


Mean age of group 1 was 73,5 ±12,6 years and 72,5±9,3 years at group 2. Patients selected to DSAEK had bullous keratopathy (11 versus 15), Fuchs disease (9 versus 3) and transplant failure (0 versus 2). Isolated DSAEK was performed in 17 versus 18 patients, DSAEK plus cataract extraction in 3 versus 1 and DSAEK plus anterior vitrectomy in 0 versus 1. Pre-op visual acuity was 0,15 ± 0,11 versus 0,14 ± 0,11, with best visual acuity in post-op of 0,41 ± 0,25 versus 0,63 ± 0,25. In 9 versus 7 patients there was a complication.


Learning the DSAEK technique is difficult and inter-independent. Although there were differences in the results of both groups, they weren’t statistically different in the majority of the parameters analyzed.
