In addition to corneal topography, there are numerous imaging devices analyzer that provide additional information about the anterior segment. These instruments allow us to precisely image, measure, and map the anterior segment structures, which provides valuable information for refractive and lens based surgeries. The devices utilize a variety of technologies including ultrasound, optical coherence tomography, Scheimpflug imaging, and wavefront imaging.
The anterior segment refers to the front-most region of the eye, and includes the cornea, iris, and lens. Typically, the phrase “anterior segment surgery” refers to surgery performed on the iris and lens (either natural lens, or synthetic intraocular lens placed during cataract surgery).
Scansys provides a professional solution for anterior segment diagnosis. It applies Scheimpflug camera which can collect 107520/230400 data points and generates 28/60 cornea tomography images in high resolution. Scansys can provide a series of topography maps including cornea curvature maps, cornea thickness maps, cornea elevation maps, etc.
