Comparison of Penetrating Keratoplasty and Deep Lamellar Keratoplasty for Macular Corneal Dystrophy and Risk Factors of Recurrence

Clinical Outcomes and Risk Factors for Graft Failure After Deep Anterior Lamellar Keratoplasty and Penetrating Keratoplasty for Macular Corneal Dystrophy

“…9,[16][17][18][19][20] In a closer comparison, Sogutlu Sari et al 15 have shown comparable BCVAs as seen in our series, whereas Cheng et al 14 have shown a better BCVA after PK compared with DALK. 9,[16][17][18][19][20] In a closer comparison, Sogutlu Sari et al 15 have shown comparable BCVAs as seen in our series, whereas Cheng et al 14 have shown a better BCVA after PK compared with DALK.…”

Visual Function and Higher-Order Aberrations in Eyes After Corneal Transplantation

“…Past reports indicated that the overall visual outcome after DALK was comparable to that after PKP. [9][10][11][12]15,16,[18][19][20][27][28][29] However, other studies reported that the best-corrected visual acuity after PKP is better than that after DALK, 14,21,22 or that DALK is better than PKP. 30 A literature review by Reinhart et al 31 reported a tendency for lower visual acuity in DALK eyes in which DM was not bared and residual stroma in the bed exceeded approximately 10% of the total stromal thickness, although there was no significant difference in the postoperative visual acuity between DALK and PKP as a group.…”

“…17,27 Corneal dystrophies, such as lattice corneal dystrophy or granular corneal dystrophy, sometimes recur after DALK, which can influence the long-term visual prognosis. 18,20,32 Although graft rejection is relatively rare after DALK, the vascularized corneal bed in eyes after herpetic keratitis can increase the postoperative stromal rejection rate compared with other nonvascularized keratoconic corneas. In eyes with herpetic keratitis, the visual outcome is better after DALK than after PKP because DALK has far fewer postoperative complications (such as glaucoma, graft rejection, and recurrence of herpetic keratitis).…”

Aetiology-specific comparison of long-term outcome of deep anterior lamellar keratoplasty for corneal diseases

“…Stromal dystrophies have been known to recur in 2.3–5.7% within the donor stroma after DALK 12–14. Cheng et al 12 reported that the incidence of recurrence was five times higher after DALK than after PK in macular dystrophy. Although there are small differences between the previous reports, our result in this study was in good accordance with these previous studies.…”
