Full-Thickness Central Corneal Grafts in Lamellar Keratoscleroplasty to Treat Limbal Dermoids

Purpose To assess the surgical outcomes in patients who underwent lamellar keratoscleroplasty with full-thickness central corneal grafts for limbal dermoids. Design Retrospective, noncomparative, analysis of a consecutive case series with chart review. Participants Ten patients (6 male, 4 female; mean age, 12.3±5.0 years; range, 5.7–22.4 years) with 10 limbal dermoids in 10 eyes undergoing lamellar keratoscleroplasty with full-thickness central corneal grafts between 1992 and 2003 at National Taiwan University Hospital were studied. Methods The medical records and external eye photographs were reviewed. Main Outcome Measures Best- corrected visual acuity (BCVA), corneal astigmatism and topography, cosmetic outcomes, and surgical complications were measured as outcome indicators. For analysis of the surgical effect on corneal astigmatism, the 9 patients with topographic data available were divided into 2 groups according to their preoperative corneal astigmatism (group 1, ≥6 diopters [D]; group 2, <6 D). Results The mean earliest recorded BCVA and the latest postoperative BCVA were 6/30 and 6/10, respectively, and the improvement of BCVA after operation combined with amblyopia treatment was 4.9±3.6 lines on a Snellen chart. Patients with preoperative astigmatism ≥6.0 D (9.7±1.0 D; n = 4) were found to have a marked decrease in astigmatism after surgery (astigmatism change, 5.2±1.7 D). Patients with preoperative astigmatism
