Keratoconus (KCN) is an eye condition that affects the cornea. The main objective of this study is to evaluate the accuracy of keratoconus detection from corneal parameters including elevation, ...

Laser refractive surgery has long been a life-changing option for those struggling with nearsightedness, farsightedness, or astigmatism. Millions have said goodbye to glasses and contact lenses thanks ...

Efficient synthetic aperture radar (SAR) processing algorithms are unable to exactly implement the aperture- and topography-dependent motion compensation due to the superposition of the synthetic ...

In nanoporous alumina, surface pretreatment prior to the anodization process plays a crucial role in the nanopore formation, strongly influencing their organization and size uniformity. In this work, ...

Topography is a key factor that governs important properties of surfaces, such as adhesion and wettability, and materials with switchable surface topographies will have switchable surface properties.

The Gaelic topography of Scotland, and what it proves, explained; with much historical, antiquarian, and descriptive information by Robertson, James Alexander, d. 1874 Publication date 1869 Topics ...

Information considered in evaluating soil characteristics and landscape features are: Soil texture and thickness and uniformity of deposits Topography Stoniness Salinity Soil drainage Soil Order and ...

Topography accurately measures the global corneal astigmatism, quantifies the nature of the astigmatism (i.e., symmetric 'bow tie' vs asymmetric or 'irregular' astigmatism) and identifies the ...

Using measurements obtained by corneal topography, patients with symmetric bow tie corneal astigmatism can be placed into one of four categories for planning purposes. These categories are shown ...

Afterwards, we establish multifractal topography to unify the scale-invariance definition of arbitrary fractal behavior, clarify the physical meaning of singularity and its significance, construct a ...

At Houston LASIK & Eye, the decision between LASIK and EVO ICL isn't left to chance. During comprehensive consultations, advanced diagnostic technology assesses corneal thickness, prescription ...
