Abstract Details



Purpose:

To evaluate donor graft thicknesses after femtosecond laser-assisted Descemet's stripping automated endothelial keratoplasty (FDSAEK) versus keratome-assisted Descemet's stripping automated endothelial keratoplasty (KDSAEK) in patients with corneal endothelial disease.

Setting:

Dokkyo Medical University School of Medicine

Methods:

An IntraLase femtosecond laser set at 410-μm lamellar cut thickness and a 350-μm keratome were used to create DSAEK grafts. A retrospective comparison of a consecutive surgical series of 37 eyes of 37 patients after DSAEK (19 corneas underwent FDSAEK and 18 corneas underwent KDSAEK) was performed. The corneal graft's center thickness was measured using optical coherence tomography (TOMY, Japan) at 12 months after surgery. A case that did not have corneal translucency was excluded from this study.

Results:

The mean corneal thickness at 12 months after surgery was 150.4±36.6 μm (range 113 - 257) for FDSAEK and 223.3±69.8 μm (range 90 - 333) for KDSAEK. The coefficient of variation was 0.24 for FDSAEK and 0.31 for KDSAEK. In both groups, measured corneal thicknesses were thicker than attempted thicknesses. The variance of thicknesses for FDSAEK was smaller than for KDSAEK.

Conclusions:

FDSAEK is a promising procedure. FINANCIAL INTEREST: NONE
