Wavefront analysis of eyes with and without cataract surgery found significant differences in the levels of aberrations between rigid and foldable IOLs and between scleral and corneal incisions.

To investigate fluctuations in the ocular surface, we used high-speed videokeratoscopy (50 Hz) to measure the dynamics of the ocular surface topography. Ocular surface height difference maps were ...

Laser in situ keratomileusis (LASIK) was initially reported by Ioannis Pallikaris in 1990 and has since become an efficient and highly popular procedure in corneal refractive surgery. However, a ...

Results of the study, "Internal compensation for corneal astigmatism and high-order aberrations of the eye," were reported to the fourth International Congress of Wavefront Sensing and Aberration-free ...

CHICAGO — Outcomes might be better with wavefront-guided (WG) photorefractive keratectomy (PRK) than with wavefront-optimized (WO) PRK for patients older than 40 years, according to a study presented ...

ABSTRACT.Curvature wavefront sensors measure wavefront phase aberration by acquiring two intensity images on either side of the pupil plane. Low-order adaptive optics (AO) systems using curvature ...

A new imaging technique known as wavefront coding is helping designers to reduce the cost and weight of imaging systems. Andrew Harvey and Gonzalo Muyo look at how the technique is being applied to ...

Entangled photon pairs, also known as biphotons, are widely used in quantum optical techniques. Quantum imaging enables several nonclassical imaging features. In particular, biphotons with a strong ...

Holographic memory records and reproduces digital data that consist of two-dimensionally aligned black and white dots (data pages). To make a hologram, it records the interference fringes that are ...
