There are now many devices that acquire data about the cornea: shape, power, pachymetry at any desired point of the cornea, corneal hysteresis, flap thickness (in LASIK procedures), endothelial cell count and morphology, and so forth. We review the literature on corneal assessment techniques and devices available in clinical practice. Specifically, we discuss slit lamp biomicroscopy, specular microscopy, ultrasound pachymetry, confocal microscopy, very-high-frequency digital ultrasound biomicroscopy, optical coherence tomography, Placido disk-based keratoscopy, slit-scanning elevation topography, Scheimpflug imaging, and dynamic applanation procedures-all of which can be used to assess the morphology of the cornea. In addition, we present a critical analysis of the instrumentation described and discuss the necessity of developing new technology for assessing both the morphology and the physiology of the cornea.
角膜的形状、屈光度、在角膜的任何所需点的厚度、角膜滞后、瓣厚度(在 LASIK 手术中)、内皮细胞计数和形态等等。我们回顾了角膜评估技术和临床实践中可用设备的文献。具体来说,我们讨论了裂隙灯生物显微镜、共焦显微镜、超声角膜测厚仪、光学相干断层扫描、基于 Placido 盘的角膜曲率计、裂隙扫描眼压计、Scheimpflug 成像和动态压平程序——所有这些都可用于评估角膜的形态。此外,我们对所描述的仪器进行了批判性分析,并讨论了开发新技术评估角膜形态和生理的必要性。
