摘 要：AIM:To determine the influence of gaps[places where neither the donor s nor the recipient s Descemet s membrane(DM)is present]and overlaps(places where the recipient s DM is covered by the donor s DM)on the frequency of postoperative detachment of DM endothelial keratoplasty(DMEK)***:Totally 64 eyes of 64 patients with Fuchs endothelial dystrophy or bullous keratopathy indicated for DMEK were randomly divided in two *** diameter of the implanted DMEK lamella was the same in both groups(8 mm),but we changed the diameter of the removed recipient *** the first group(32 eyes),the circular area was approximately 8.5 mm(gaps);in the second group(32 eyes),the diameter was 7.5 mm(overlaps).Postoperatively we noted all cases of detachment visible on the slit lamp and these cases we indicated for *** also measured the uncorrected distance visual acuity(UDVA)as well as corrected distance visual acuity(CDVA)in decimal and postoperative endothelial cell density(ECD).The minimum follow-up time was ***:The number of rebubbling procedures in the entire group of patients was 13,i.e.,20.3%,with 6 eyes(18.7%)in the gap group,and 7 eyes(21.9%)in the overlap *** replacement(re-DMEK)was required in 3(gap group)and 2 patients(overlap group),*** dif ference between the groups was statistically *** UDVA was 0.54±0.21 in the gap group and 0.58±0.24 in the overlap *** CDVA was 0.74±0.22 and 0.80±0.16,*** was 1920±491 and 2149±570 cells/*** small differences between both groups were not statistically ***:We do not notice any difference in the group of patients with overlaps or gaps of *** presence of small areas of gaps or overlaps does not affect the frequency of detachment of the DMEK lamellae.
