Medium-term clinical outcomes of deep anterior lamellar keratoplasty vs penetrating keratoplasty for macular corneal dystrophy
Clinical Ophthalmology Jul 29, 2021
AlAraj A, et al. - In this single-center, retrospective, interventional case series, researchers sought to compare the postoperative outcomes of deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PKP) for macular corneal dystrophy (MCD). Participants in the study were 100 patients (157 eyes) with histopathologically proven MCD. The DALK group had 22 eyes and the PKP group had 135 eyes. The authors discovered that 90.9% of the DALK group and 76.3% of the PKP group achieved postoperative best-corrected visual acuity (BCVA) of 20/40 or better. DALK is a viable treatment option for MCD that does not involve the Descemet membrane. DALK and PKP had comparable medium-term visual and survival outcomes. DALK has fewer open-sky intraoperative complications and graft rejection episodes.
