Overview

Comparative study reveals equivalent visual acuity and graft survival between lamellar and full-thickness keratoplasty in macular corneal dystrophy, indicating lamellar surgery is a viable...

Key Points

To compare postoperative visual outcomes, corneal tomography parameters, complication rates, and graft survival between deep anterior lamellar keratoplasty and penetrating keratoplasty in macular corneal dystrophy.
Enrolled 59 patients (81 eyes; 23 male, 36 female) with macular corneal dystrophy.
Assigned 64 eyes to penetrating keratoplasty (PK) and 17 eyes to deep anterior lamellar keratoplasty (DALK).
Compared best-corrected visual acuity, corneal tomography, pachymetry, complications, and graft survival at 12 months post-surgery.
Achieving best-corrected visual acuity of 20/40 or better occurred in 70.6% of DALK eyes compared to 75.0% of PK eyes (p=0.712).
Graft survival was 88.2% in DALK versus 87.5% in PK (p=0.88), with regrafting required in 11.8% and 9.4% of eyes, respectively (p=0.769).
Interface opacity occurred in 41.2% (7 eyes) of the DALK group, while front Kmean (p=0.037) and Q values (p<0.01) were significantly lower in DALK compared to PK.
