Suture technique for Descemet stripping and endothelial keratoplasty.
OBJECTIVE
To describe a suture technique for Descemet stripping and endothelial keratoplasty (DSEK).


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
