    Recent studies evaluating intraocular pressure (IOP) measurements by dynamic contour tonometry (DCT) have shown that they are more comparable to true manometric IOP than Goldmann applanation tonometry (GAT),1 and less affected by changes in naturally occurring central corneal thickness (CCT)2,3 as well as surgically induced thinning of the cornea following laser in situ keratomileusis.4 Following penetrating keratoplasty, further errors in the measurement of IOP by GAT may also occur due to irregular astigmatism, and technical difficulties in aligning distorted mires on the tonometer head.

    We prospectively studied 10 patients with unilateral keratoplasty to detect a significant …
