New technique of deep anterior lamellar keratoplasty
2011
We present a simple, effective and reproducible technique of deep anterior lamellar keratoplasty.
Using a diamond knife, set at 90% of corneal thickness at (90 degrees meridian), at
8 mm optic zone, a radial incision was done and corneal pockets were created. A 6.0 nylon
preloaded spatula was then inserted into the corneal pocket and in a counterclockwise
direction rotated in 3600 to create a deep stromal tunnel. A partial-thickness 8 mm trephination
was done. The spatula was removed from the tunnel and the nylon wire was pulled
from both sides of the radial incision to dissect deep to the corneal stroma leaving little
residual stroma over the Descemet’s membrane. The residual anterior stroma is removed
with a Vannas scissors. The donor button is sutured. The main advantages of this technique
are the very low learning curve and the regular stromal dissection with almost no residual
tissue over the Descemet’s membrane.
