14.2 Position and depth of INTACS rings
®
As described elsewhere in this Interpretation Guide, Pentacam® examinations can be extremely
useful both in planning for surgery and following up patients. The densitometry screen can add an
extra dimension to the follow-up. A 35-year-old patient with a history of stable keratoconus was
treated by implantation of INTACS® corneal ring segments. The segments are readily visible in the
densitometry screen (Figure 127). The depth of the rings can also be seen, measured and followed
up over time, and all measurements can be made from a single Pentacam® scan.
