Abstract:
Deep anterior lamellar keratoplasty (DALK) is a surgical technique that involves the removal of pathological corneal stroma down to Descemet membrane and replacing it with a donor cornea. Over the last decade, there has been a paradigm shift in the surgical techniques of DALK, which has made it safer with visual outcomes comparable with penetrating keratoplasty. This review aims to discuss the existing popular techniques of DALK, their advantages and limitations. We will also describe techniques of DALK that are useful in special situations.
