    SS-OCT Better Than Scheimpflug for Corneal Thickness

    Swept-source Fourier-domain optical coherence tomography (SS-OCT) yields better corneal thickness measurements than the Scheimpflug camera for patients with Fuch's endothelial corneal dystrophy (FECD) or an endothelial transplant, a recent study found. Researchers from Spain compared repeatability and reproducibility coefficients of the two imaging modalities between 36 control eyes, 35 FECD eyes, 30 FECD eyes with corneal edema, 25 eyes after Descemet stripping automated endothelial keratoplasty and 29 eyes that had Descemet’s membrane endothelial keratoplasty. While both systems showed high corneal thickness reproducibility and repeatability, SS-OCT results were higher and more precise across patient groups—often significantly so. “The ...
