HD Cornea Scan
This (anterior segment) scan generates a single high–definition scan with a depth of 2.0
mm that has a wider field of view than the Anterior Segment 5 Line Raster. The scan uses
20 B-scans, each composed of 1024 A scans. The scan is 9.0 mm in length when oriented
horizontally and has a depth of 2.0 mm. The scan is adjustable from –89 to 90 degrees.
This scan requires the Cornea external lens. The HD Cornea Scan provides the data for the
HD Cornea Analysis (
"Corneal Thickness" on page 8-43
).
The Acquire screen displays the position of the HD Cornea scan pattern on the live iris
image
and displays the OCT image of the scan on the right. The HD Cornea scan requires
the Cornea external lens.
