Comparion of Deep Lamellar Keratoplaty and Penetrating Keratoplaty for Lattice and Macular Corneal Dytrophie Original Reearch Article

Purpoe To compare the therapeutic outcome after deep lamellar keratoplaty (DLKP) and penetrating keratoplaty (PKP) in patient with lattice corneal dytrophy (LCD) and macular corneal dytrophy (MCD). Deign Age-matched control tudy. Method We reviewed the clinical record of 84 eye with LCD or MCD who had DLKP (41 eye) or PKP (43 eye). Primary pathology conited of 60 eye with LCD and 24 eye with MCD. DLKP wa performed by either removing tromal tiue gradually, or by vicodiection of Decemet’ membrane. Graft clarity, bet-corrected viual acuity (BCVA), endothelial denity, and complication were compared between DLKP and PKP, a well a between LCD and MCD. Reult All 84 eye howed a potoperative improvement in viual acuity. The median final BCVA wa not ignificantly different between PKP and DLKP group. Endothelial cell lo rate were imilar for DLKP and PKP. While the MCD-DLKP group howed progreive decreae in endothelial denity, thi wa not oberved in the LCD-DLKP group after urgery. In the DLKP group, mot of the complication occurred intraoperatively or in the early phae, wherea late phae complication uch a endothelial rejection and econdary glaucoma were the main complication in the PKP group. Concluion PKP i no longer an automatic choice for the urgical treatment for LCD and MCD; DLKP eem to be a afe alternative. While DLKP i a favorable method for LCD, MCD may not be a good candidate, a it might how progreive decreae in the corneal endothelium potoperatively.
