Improving estimation of corneal refractive power by measuring the posterior curvature of the cornea.
We developed a formula to measure the posterior curvature of the cornea. In our study, real corneal power in 51 eyes was calculated by using anterior and posterior curvatures and corneal thickness. The corneal refractive index was found to be a variable value between 1.3243 and 1.3339 (mean 1.3304 +/- 0.0003).
