Corneal Changes Associated With Intrastromal Corneal Ring Segments

Arch Ophthalmol. 1999;117(2):282. doi:10.1001/archopht.117.2.282

THE CORNEA of an asymptomatic male patient was examined routinely 2 years after the implantation of intrastromal corneal ring (ICR) segments (Figure 1 and Figure 2).

Ophthalmic examination revealed an intraepithelial concentric ring of iron deposition central to the segments. Along the central and peripheral borders of the ICR segments was a mild intrachannel opacification. Within the central area of intrachannel opacification were scattered white deposits that had a mixed crystalline/amorphous appearance.
