ⓘ Toric Marker

Toric Markers are markers made for marking on the outside of the cornea or sclera part of the eye. They are designed with semi-sharp or pointed line or dot patterns.

There are two types of markers - markers pre-op and Intra-OP markers.

Preoperative markers: they are used before the patient is admitted for surgery. Marking is performed when the patient is sitting, looking forward. Templates usually two lines that indicate one of the following

  • Rotatable head - with two lines that are in the same line on the opposite sides of the circle.
  • Horizontal 0-180 lines for a pre-op marker.
  • Dot patterns - indicating opposite sides of the circle, on the same line, for a horizontal 0-180.

Intra-OP markers: they are used during surgery, with the patient lying on the surgical table and the doctor working with a microscope. In some cases, markers are used during surgery, along with the sensor degree.

  • Two straight lines - with two lines that are in the same line on the opposite sides of the circle, designed to work with a degree gauge.
  • Dot patterns - indicating opposite sides of the circle, on the same line, for a horizontal 0-180.
