Changes in Corneal Curvature After Epiblepharon Surgery in Children

Purpose: We aimed to determine the change in corneal topography for 2-different corneal zones and 4-quadrants after epiblepharon correction in children. Methods: We retrospectively reviewed 39 patients (74 eyes) who underwent epiblepharon surgery. Keratometry measurements of corneal curvature were performed for 2 optical zones defined as circular areas with a radius of 3 and 5 mm from the corneal apex. Each optical zone was divided into quadrants (nasal, superior, temporal, and inferior). Keratometry readings for each quadrant of zone were compared between the preoperative and postoperative examinations (at 1, 3, and 6 months). The correlation between corneal astigmatism and curvature change was analyzed for each quadrant of the 3-mm optical zone. Results: At 1 month postoperatively, the inferior and superior quadrants of the 3-mm optical zone became significantly flatter compared with the preoperative state, and this phenomenon became more pronounced at 3 months postoperatively (P
