Anterior Lamellar Keratoplasty

Deep anterior lamellar keratoplasty (DALK) is a surgical procedure for removing the corneal stroma down to Descemet’s membrane. The anterior corneal surface of the recipient eye is cut with a suction trephine set to a depth of about two-thirds of the corneal thickness. Then the stromal layers are dissected with a rounded blade, angled parallel to Descemet’s membrane. Fluid or air is then injected using either a 27- or 30-gauge cannula in between the deep stroma and Descemet’s membrane to separate those layers. For the donor eye, Descemet’s membrane and endothelium are removed by gently swabbing the posterior corneal surface of the donor corneoscleral rims with dry cellulose sponges. Forceps also may be used for removing the posterior corneal layers. Then a corneal button is punched out from the tissue.

Using a microkeratome to perform an Automated Anterior Lamellar Keratoplasty is a standardized, technically easy, highly precise procedure.  The dedicated equipment from MORIA is designed to be easily learned and used by surgeons experienced in microkeratome techniques.
