PKP, BCVA was 20/50 and 20/40 in the right and left eyes respectively with MR (-3.75 + 6.00 x 42; -6.25 + 3.00 x 172). Pentacam topography (Oculus Inc, Wetzlar, Germany) revealed a similar pattern of irregular astigmatism of the right eye compared to preoperative topography, with equivalent K readings at the 4.3 mm zone of 34.4 D at 122.5 degrees and 37.9 D at 32.5 degrees (Figure 4).
