    Depth of intrastromal corneal ring segments by OCT

    The OCT measurement is one of the few ways to measure precisely the depth of the ICRS in the corneal stroma. The vertical resolution of the OCT is 6 μm according to the manufacturer’s manual, supporting the validity of the measurements obtained herein. The current study demonstrates that the mean measured depth of the segments was 120 μm less than the planned depth (360±68 μm, instead of the expected 480 μm). In other words, with a mean corneal pachymetric thickness of ~600 μm at the ICRS insertion area, the mean postoperative segment depth
