The increasing volume of patients interested in refractive surgery and the new treatment
options available for keratoconus have generated a higher interest in achieving a better …

Wavefront-guided excimer laser refractive surgery and new customized intraocular lens and
contact lens designs are major clinical applications of corneal wavefront analysis. Other …

Purpose. This study was designed to compare higher order aberrations of the cornea and of
the eye with inferior-superior (IS) corneal topographic values in keratoconic eyes. Methods …

Custom high-resolution high-speed anterior segment spectral domain Optical Coherence
Tomography (OCT) was used to characterize three-dimensionally (3-D) corneal topography …

The reduction in visual performance typically found in keratoconic patients is believed to be
associated with large magnitudes of uncorrected irregular astigmatism and higher-order …

The anterior surface of the cornea has the greatest refractive power of the human visual
system. Therefore, small variations in its curvature give rise to important changes in the …
