Easy Bubble: Pachymetry-assisted Big-Bubble Deep Anterior Lamellar Keratoplasty
We present a simple, effective and reproducible technique for deep anterior lamellar keratoplasty. Using a diamond knife, set at 90% of corneal thickness (90 degrees meridian), at the limbus a radial incision was made and a corneal pocket was created. A specially designed cannula was placed deep into the corneal stroma and air was injected for stromal dissection. The air bubble pushed down Desc...
