Purpose: To analyze the clinical results of Goldmann applanation tonometry (GAT) and Pascal dynamic contour tonometry (PDCT) and the influences of central corneal thickness and keratometric power in eyes that underwent EpiLASIK or penetrating keratoplasty. Methods: Measurements of intraocular pressure by GAT and PDCT as well as keratometric power and central corneal thickness were measured in 45 eyes that underwent penetrating keratopasty and 63 eyes that underwent EpiLASIK. These parameters were also measured in healthy eyes with no specific disorders to create a control group. Results: In the keratoplasty group, the PDCT results were significantly higher than the GAT results by 1.22±2.84 mmHg (p=0.006), but neither method showed a significant correlation with CCT or keratometric power. In the EpiLASIK group, PDCT was higher as 3.45±2.35 mmHg than GAT, and the corrected results of GAT were not different from the results of PDCT. In the control group, GAT was affected by central corneal thickness and keratometric power, but PDCT showed no significant relationship with these two factors. Conclusions: After EpiLASIK or penetrating keratoplasty, both of which change CCT and keratometric power, IOP cannot be accurately measured by GAT. In these patients, PDCT may play an important clinical role since it is less affected by corneal properties.
