In selected patients, quality of vision after DALK was comparable to that after PK when stromal excision was extended to the DM and inferior to vision after PK when layers of stroma were left adherent to the DM. Advances in DALK technique are required to allow easier and repeatable baring of the DM.

DALK may be proposed in alternative to penetrating keratoplasty for the treatment of patients with keratoconus with poor visual result after ICRS implantation. DALK Big bubble technique may be carried out with ICRS in place. Visual and refractive outcomes are comparable with standard penetrating keratoplasty in patients with keratoconus.
