Deep anterior lamellar keratoplasty with femtosecond-laser zigzag incisions.

We describe a technique that uses IntraLase-created zigzag incisions for deep anterior lamellar keratoplasty. In this technique, the laser creates a precise incision that extends to within 70 microm of the recipient Descemet membrane. The deep incision minimizes air escape into the peripheral cornea during big-bubble formation.
