Le résumé fourni par la source

Anterior lamellar keratoplasty (ALK) involves a partial- or full-thickness resection of the corneal stroma that is replaced by donor tissue. Numerous techniques have been developed for ALK including manual free hand dissection, 1 microkeratome-assisted ALK, 2 , 3 and deep anterior lamellar keratoplasty (DALK). DALK is a full-thickness, or near–full-thickness, stromal resection down to, or close to, Descemet’s membrane (DM). Common indications for DALK include keratoconus and other corneal ectasias, stromal dystrophies, stromal scars and opacities, corneal ulcers, and corneal perforations. Corneal pathologies affecting the endothelium are contraindicated for DALK.
