Introduction: The purpose of this study is to investigate the longitudinal changes in corneal curvature and refractive components after suture removal in full-thickness corneal laceration using Swept Source Anterior Segment Optical Coherence Tomography (SS AS-OCT). Methods: Thirty patients were included in this study. The patients were divided into three groups according to the location of the wound on the cornea: central, paracentral and peripheral. SS AS-OCT was performed before corneal suture removal, 1 hour, 1 week and 2 weeks after corneal suture removal. The corneal curvature parameters and Fourier indices were compared longitudinally in each group. Results: After removing the corneal suture, the changes in aveK and spherical component were mostly in the first week, and less than 0.25D in the second week except the spherical component in the central group. The cylinder, regular astigmatism, asymmetry, and higher-order irregularity decreased after suture removal. The patterns of change in the refractive components differ a little with different location of the wound. The best-corrected visual acuity improved after suture removal in all groups. Conclusions: The current study demonstrates the changes in corneal curvature and refractive components after corneal suture removal in various locations of corneal laceration. This information provides a reference for deciding the time and strategy of subsequent procedures for visual rehabilitation.
