IOPg and IOPc Reduction Analysis Following LASIK and PRK. The paired IOP reduction following LASIK measured with IOPg and IOPc was −3.27 ± 3.01 mmHg and 1.93 ± 3.30 mmHg, respectively (Table 3). Following PRK, the paired IOP reduction measured with the GAT and Mod. GAT prisms was − 1.92 ± 3.60 mmHg and − 1.06 ± 3.58 mmHg, respectively. Box-whisker plots of the paired IOP reduction following both CRS procedures shows IOP was reduced post-operatively both prisms, but to a significantly lesser degree with IOPc (Fig. 1)
