[Scheimpflug and topography systems in ophthalmologic diagnostics].
Modern Ophthalmology is currently experiencing a boom in anterior segment analysis tools that can increasingly gather information with one short measurement. These systems are based e.g. on so-called Scheimpflug (Pentacam, Galilei), slitlamp, and Placido technologies (Orbscan IIz) and other measurement systems. They help in analyzing the cornea in detail, including calculation of corneal wavefront. In addition, morphological and anatomical parameters such as anterior chamber depth, pachymetry, chamber angle, and lens densitometry can be analyzed. That makes these new technologies of interest for refractive surgery as well as for screening procedures such as Glaucoma, Keratoconus and others. This survey focuses on the two models, Oculus Pentacam and B&L Orbscan IIz as representative of all the other systems, as they are the most successful machines in this field.
