Endothelial Side Up Inverted Femtosecond Laser Assisted DSAEK a Pilot Study
Dar El Oyoun Hospital
15 participants
Jan 1, 2022
INTERVENTIONAL
Conditions
Summary
To evaluate the clinical outcomes (pos toperative best corrected visual acuity, endothelial count) and anatomical results (interface smoothness) of DSAEK with Femto LDV-prepared grafts from the endothelial side.
Eligibility
Inclusion Criteria1
- Patients with Fuchs' endothelial dystrophy Patients with bullous keratopathy secondary to intraocular surgeries, iridocorneal endothelial syndrome, or viral keratitis
Exclusion Criteria1
- Bullous keratopathy secondary to glaucoma or ocular trauma Corneal stromal scarring or opacities Diseases not affecting the corneal endothelium, including corneal ectasia (e.g., keratoconus, keratoglobus, pellucid marginal degeneration) Epithelial, Bowman layer/anterior stromal, and stromal dystrophies Hypotonic eyes Retinal diseases Any type of optic atrophy

Interventions
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.
