Comparison of penetrating keratoplasty versus lamellar keratoplasty for macular corneal dystrophy: a retrospective study of a single-center experience

Background: Although penetrating keratoplasty (PK) still remains the dominant form of transplantation for macular corneal dystrophy (MCD) patients, many studies evaluating these new forms selective lamellar (LK) now suggest equivalent or better visual outcomes. This study aimed to explore difference in outcomes and complications that follows each type operations. Methods: A retrospective, single-center was performed at King Abdulaziz medical city 2022. The included patients with a histological diagnosis MCD who undergone either PK LK. Data collected from health records using consisted patient characteristic, operation post-operative outcomes, including acuity, survival rate complications. Results: total 54 eyes have MCD. best corrected acuity (BCVA) 0.5 achieved 82.5% group 42.9% LK group. Graft 90% (36 eyes) 85.7% (12 groups respectively. Regarding complications, four (10%) one eye (7.1%) had high intraocular pressure, three (7.5%) developed rejection, (2.5%) recurrent epithelial erosion, another Traumatic laceration. Conclusions: operations resulted compared graft slightly associated higher incidence than
