To describe a suture technique for Descemet stripping and endothelial keratoplasty (DSEK).
The technique was performed in 2 eyes of 2 patients with Fuchs endothelial corneal dystrophy. A double-armed 10-0 prolene suture on a CIF-4 needle was used to pull the donor corneal button into the recipient's anterior chamber without the use of forceps to hold the button. The suture was also used to unfold the lenticule in the eye without marking the stroma with gentian violet, to center the lenticule and to secure that in place.
No intraoperative problems occurred in either case. The suture technique was successfully used to pull the donor button into the host's eye and to unfold and center the button. Both lenticules were well centered and had minimal corneal edema. At 6 months, the central endothelial loss was 8% in the first case and 10% in the second.
This suture technique for DSEK avoids the use of forceps and allows less traumatic donor button manipulation. It may be an effective alternative with low endothelial damage; further follow-up will determine the long-term effect on the central endothelial cell count.
描述一种用于后弹力层剥除内皮角膜移植术（DSEK）的缝合技术。
该技术应用于2例患有Fuchs内皮角膜营养不良患者的2只眼中。使用一根CIF - 4针上的双臂10 - 0聚丙烯缝线将供体角膜片拉入受体前房，无需使用镊子夹持角膜片。该缝线还用于在眼中展开晶状体，无需用龙胆紫标记基质，使晶状体居中并固定在位。
两例均未发生术中问题。该缝合技术成功用于将供体角膜片拉入宿主眼内，并展开角膜片使其居中。两个晶状体均居中良好，角膜水肿轻微。6个月时，第一例中央内皮细胞损失为8%，第二例为10%。
这种用于DSEK的缝合技术避免了使用镊子，减少了对供体角膜片的创伤性操作。它可能是一种内皮损伤低的有效替代方法；进一步随访将确定对中央内皮细胞计数的长期影响。
