110 9. SUMMARY Introduction The endothelial dysfunction and related corneal oedema with decreased transparency id still the main indication for keratoplasty. Method of posterior lamellar keratoplasty, which is popular in oftalmology in last few years, is suitable method because we exchange just the affected part of the cornea. Nowadays there are more surgical ways and modalities of the technique, but the best way has not been established yet. Purpose Purpose of our study was: to evaluate and analyze the efficacy of new technique of lamella preparation, to evaluate new method of lamela implantation and to analyse anatomical outcomes in experiment and clinical outcomes in practice. Materials and methods Group 1 involves 71 eyes of 55 patients, who underwent posterior lamellar keratoplasty with implantation of a hybrid lamella DMEK-S using a hydroimplantation. In group 2 were enrolled 27 eyes of 22 patients, who underwent posterior lamellar keratoplasty with implantation of a hybrid lamella DMEK-S using glide. In the postoperative period, we evaluated corrected and uncorrected visual acuity and corneal endothelial density. We analyzed and compared clinical outcomes of both groups and we focused especially on the method of implantation. Student t test and Bonferroni test were used for all statistical analysis....
