2mm Punch/Micro Stromal
Stamp Combination
After creation of either the peripheral or
central hinge, a 2mm trephine is used to
punch through the remainder of the
stromal bed. The 2mm punch plug is
removed and the Descemet's is returned to
the stromal bed. The stamp is then applied
to the stromal side of Descemet's through
the 2mm hole from the epithelium side of
the tissue. The 2mm punch plug is
replaced during transport.
Endothelium
Fold-Over Micro Stromal Stamp
After creation of the peripheral hinge,
the edge of the Descemet's is left on a
dry area of the scleral rim, and the
stamp is applied directly to the stromal
side of Descemet's. The Descemet's is then
returned to the stromal bed.
Single Partial
Trephination Options
Standard: 9.5mm
Other options: 8.0, 8.5
and 9.0mm
Double Partial Trephination Options
Standard 9.5mm single partial trephination
7.25, 7.5, 7.75 or 8mm double partial trephination
1mm Trephination Series
(View from endothelium)
After creation of either the peripheral or
central hinge, the Descemet's is returned to
the stromal bed. A 1mm trephine is then
used to punch through the Descemet's at
the periphery of the partially trephinated
button. When viewed from the endothelium
side, the 1mm trephine series will be seen
as half-circles at 12, 1 and 4 o'clock.
Corneas and markings are to scale and shown at approximately 300%.
