--- Objective: To determine the differences in the measurements of Dynamic contour tonometry and Goldmann applanation tonometry in relation with the thickness and the corneal curvature. Methodology: Study transverse, a sample was obtained by convenience, included 116 patients’ eyes went to the Oftalmosalud social program, without ocular pathology, showed through February to April, 2009. They took measures of the thickness, corneal curvature, pressure for CDT and AGT. Results: The age average of the participants was of 55 years, 52.58% males. The stocking of the IOP one for contour dinamic was 19.3 mmHg and for applanation tonometry 16.32mmHg, existing significant differences among both mensurations of IOP (p less 0, 0006). The thickness of the central cornea for paquimetry was 539.4 on the average and the stocking of the corneal bend in dioptrias of 43.28. The comparisons of the stockings of the IOP one of AGT and CDT according to the thickness corneal power station (CCT) are significant in the measures smaller to 500 microns (p less 0.000001). According to the corneal curvature stays with significant differences ways being bigger with CDT. Conclusions: The tonometry of contour dinamic overestimates the IOP one compared with the applanation tonometry significantly. The IOP one evaluated with both instruments compared with the corneal thickness shows significant differences, being similar in corneas among 500 to 549 microns.
