Penetrating and Deep Anterior Lamellar Keratoplasty for Keratoconus: A Comparison of Graft Outcomes in the United Kingdom

Abstract

DALK had a higher overall failure rate than PK. The difference was largely accounted for by early failures, which appeared to be related to the surgeon's experience. DALK recipients were less likely to achieve BCVA of 6/6 than were PK recipients and were more likely to have -3 D or worse myopia.
