    Glossary [AS] : Auto Shot. Function to automatically start measurement when the patient's eyes are within the measuring range. [MS] : Manual Shot [AA] : Alignment Assist. Auxiliary alignment function in vertical direction only. When the patient’s eye is close to the measuring range, the head position automatically moves up/down toward the alignment target.

[RING TOPO mode] : Similar to conventional TMS, a mode to capture images of the anterior shape of the cornea by projecting ring-shaped light onto the cornea of the patient’s eye [Slit mode] : Image of a corneal cross-section captured using the Scheimpflug principle in slit mode...
  • Page 21 [Absolute scale] : Absolute scale (ABS) uses the color coding developed by Professor Stephan D. Klyce of Louisiana State University (LSU). It divides the range between 9 and 100 diopters into 26 sections, and allocates specific colors. For all eyes measured, this scale shows the same refractive power for all parts with the same color, thereby facilitating comparison with other measurement results.
  • Page 22 [Picture perfect] : Manual mode with automatic correction This function of the TMS series automatically corrects errors in sight alignment generated by the physician in the left/right (X axis), up/down (Y axis), and back/forth (Z axis) directions. This function is also designed to display the most accurate map possible by capturing images in a range with the X, Y, and Z offset, using the software.

  • Page 23: Indication For Use

    Indication for Use TMS-5 is an anterior segment analyzing system that is designed to capture Scheimpflug images and topographer measurements of the anterior segment of the eye to provide information including anterior/posterior corneal topography, anterior/posterior corneal elevation maps,pachymetry and anterior chamber depth.
