  • Endothelial Side Up Femtosecond Laser Assisted DSAEK

    Procedure/Surgery

    The Femto LDV Z8 laser system will be set to create a 100 μm thick graft with a 7.5 mm diameter. The graft will be inverted, placed endothelial side up in the anterior chamber, and coated with Viscoat. A fixation ring will center the graft by holding the scleral rim with forceps. After cutting, the cornea should remain endothelium-up, stained with Trypan Blue, and dissected using a blunt spatula. The graft will be placed on a Busin glide and coated with Viscoat. A 3-4 mm corneal incision will be made, and Descemet's membrane will be marked and stripped. The graft will be inserted using the Busin glide, spreading automatically. A small air bubble will fill the anterior chamber to compress the graft for 10 minutes.
