Figure 3: The relationship between measured IOP and corneal thickness pre -and post-enhancement. Units of IOP (y axis), mmHg. Units of corneal thickness (x axis) μm. The equation of the pre-enhancement linear regression line is: y=0.0313x-3.35 (r=0.740, n=30, p<0.0001). The equation of the post-enhancement linear regression line is: y=0.0243x-0.018, r=0.675, n=30, p<0.0001.
