Thickness Measurements of Donor Posterior Disks After Descemet Stripping Endothelial Keratoplasty With Anterior Segment Optical Coherence Tomography
Purpose: To evaluate donor posterior disk thickness measured with anterior segment optical coherence tomography after Descemet stripping endothelial keratoplasty. Methods: Fifteen patients (17 eyes) after Descemet stripping endothelial keratoplasty, using manually dissected donor posterior disks, were measured with the Visante anterior segment optical coherence tomography (Carl Zeiss Meditec Inc, Dublin, CA). Optical coherence tomography scans were made in a radial pattern, 45 degrees apart, starting in the horizontal axis. Thickness measurements of the donor posterior disks were taken centrally and at fixed radii toward the periphery and were correlated to postoperative change in spherical equivalent (SE), best-corrected visual acuity (BCVA ...
