Feizi S, Ali Javadi M, Abolhosseini M, et al. - In this retrospective comparative interventional case series, researchers compared the outcomes of penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) for pediatric keratoconus. This investigation involved consecutive pediatric keratoconus cases (≤ 18 years of age) who received PK (n = 45) or DALK (n = 54) in two different time periods. In pediatric keratoconus, no significant difference was noted in the outcomes between PK and DALK. In contrast to PK, low-quality donor tissues in DALK increased the incidence of graft epithelial problems and complications associated with sutures.
