We determined the “normal” central corneal thickness (CCT) value in human corneas based
on reported literature values for within-study average CCT values, and used this as a …

Most human eyes show at least a small degree of corneal astigmatism and it can arise from
both surfaces of the cornea. The shape of the anterior corneal surface provides no definitive …

PURPOSE: To determine the contribution of posterior corneal astigmatism to total corneal
astigmatism and the error in estimating total corneal astigmatism from anterior corneal …

There is a need for a schematic eye that models vision accurately under various conditions
such as refractive surgical procedures, contact lens and spectacle wear, and near vision …

PURPOSE: To determine the shape and astigmatism of the posterior corneal surface in a
healthy population with age, using Scheimpflug photography corrected for distortion due to …

OBJECTIVE: To quantitatively evaluate the changes in anterior and posterior corneal
curvatures of eyes with keratoconus. DESIGN: Case-control retrospective and observational …

Purpose: To obtain the shape of the posterior corneal surface in a healthy population, using
Scheimpflug photography corrected for distortion due to the geometry of the Scheimpflug …

Purpose.: Description of total corneal refractive power (TCRP) astigmatism by ray tracing
using a Scheimpflug tomographer. Methods.: Analysis of Scheimpflug tomography …

The in vivo spherical aberration of the lenses of 26 subjects was estimated from the
measured total aberration of the eye and that predicted from the measured shape of the …

PURPOSE: To determine the keratometric index based on actual measurements of the
anterior and posterior corneal surfaces using a rotating Scheimpflug camera (Pentacam …
