Newer variants of deep anterior lamellar keratoplasty (DALK) technique have emerged in the last decade, targeted to replace diseased corneal stroma with health endothelium selectively. Recent improvements in surgical instruments and the introduction of new imaging systems, have resulted in the standardization of DALK as an acceptable alternative to conventional PK. In this article, a deep trephination within 150 μm from the endothelial surface allows pneumatic dissection to be performed successfully in a very high percentage of cases even by surgeons with minimal experience of keratoplasty surgery. Moreover, the air injection from a cannula advanced minimally from the base of a deep trephination eliminates the need for subjective judgment of the depth reached during cannula advancement to the center of the cornea. Results concerning visual acuity, refractive outcomes, and graft survival rate are analyzed and reported.
