111940​ Corneal axial power map​

A two dimensional representation of the axial curvature​

of the cornea. Axial curvature is calculated from the​

reciprocal of the distance from a point on a meridian​

normal at the point to the corneal topographer axis. Also​

known as sagittal curvature.​

111941​ Corneal instantaneous power​ A two dimensional representation of the instantaneous​

map​

curvature of the cornea. Instantaneous curvature is​

calculatedfromthereciprocalofthedistancefromapoint​

on a meridian normal at the point to the center of​

curvature of that point. Also called tangential curvature.​

of the cornea. Corneal refractive power is calculated​

using Snell's Law.​

111943​

Corneal elevation map​

A two dimensional representation of the elevation of the​

cornea. Elevation is calculated as the distance from a​

point on the corneal surface to a point on a reference​

surface along a line parallel to the corneal topographer​

axis. For the purpose of visualization the reference​

surface is usually a sphere or an ellipse.​

111944​

Corneal wavefront map​

A two dimensional representation of a wavefront​

aberration surface of the cornea. Wavefront aberration​

surface is calculated from the corneal elevation data fit​

with either the Zernike polynomial series or the Fourier​

Series. Maps generally display total aberrations and​

selectable higher order aberrations.​

Elevation-based corneal​

A device that measures corneal anterior surface shape​

tomographer​

using elevation-based methods (stereographic and light​

slit-based). Rasterstereography images a grid pattern​

illuminatingthefluoresceindyedtearfilmwith2cameras​

to produce 3D. Slit-based devices scan the cornea,​

usually by rotation about the instrument axis centered​

on the cornea vertex.​

111946​

Reflection-based corneal​

A reflection-based device that projects a pattern of light​

topographer​

onto the cornea and an image of the reflection of that​

pattern from the tear film is recorded in one video frame.​

Light patterns include the circular mire pattern (Placido​

disc) and spot matrix patterns. Sequential scanning of​
