Abstract Details


We demonstrate a new technique for the preparation of a super thin lamella for DSAEK and comparing this new method with published results in terms of complications and visual outcomes in DMEK.


Eye Hospital Bellevue, Kiel, Germany


For lamella preparation we used the SCHWIND artificial chamber and the SCHWIND Carriazo-Pendular Microkeratom. For measuring thickness of the corneal graft we used the Palm Scan AP 2000 with an ultrasonic probe frequency of 50MHz. Depending on the pachymetry a combination of the cutting heads is calculated. Usually two cuts are necessary for producing a Superthin lamella. First cut 110 microns, second cut 400 or 450 microns. For loading the implantation spatula the DSAEK Flap is swimming in a bowl. Than we bring the spatula under the swimming Flap and lift it up.


25 eyes have been treated with swimming DSAEK method. Preoperative mean DCVA (distance corrected visual acuitiy) logMAR was 0,6. Six months postoperative, 8 eyes achieved DCVA logMAR of 0,1; 12 eyes achieved DCVA logMAR of 0,2 and 5 eyes result in DCVA logMAR of 0,4. The mean grafts thickness six months postoperative was 70±20microns. No grafts have been lost through cutting procedure.


The swimming DSAEK method is a nice alternative to DMEK operation. Costs are lower as lamellar loss hardly exists. Safety, efficiency, predictability are comparable to DMEK procedure.
