Apparatus and method for determining corneal and scleral topography
TL;DR: In this paper, an apparatus and method for determining the topography of the cornea and sclera of the human eye is presented, where the selected area's location is measured from at least one additional orientation different from that of the incident light beam by focusing an image of the fluorescence emissions from the selected areas onto the surface of a positive sensitive detector.

Speckle Patterns in Partially Coherent Light
TL;DR: In this paper, the effects of light of arbitrary coherence may be considered, and the results derived in that section are the only new results presented here; the rest of the material is taken from published work, much of which has been reported during the last five years.
Journal ArticleDOI
Review and classification of corneal topographers.
TL;DR: The purpose of the study reported here was to make an inventory of developed devices, analyse the basic principles and create a classification based on optical principles that can be used by researchers and practitioners to gain insight into the possibilities of a given device in relation to the desired application.
Journal ArticleDOI
Calculation of an IOL from the wide-angle optical model of the eye.
TL;DR: The effect of corneal asphericity on IOL performance is studied and the use of a wide-angle optical model of the aphakic eye for computation of the IOL would result in values that approach more closely those in the real eye.

Corneal Contour of the Human Infant
TL;DR: The infant corneal contour has shorter radii but is geometrically similar to the adult cornea, which partially corrects for ocular spherical aberration at birth and thereby contributes to maximum visual acuity.
Journal ArticleDOI
New photokeratoscope utilizing a hemispherical object surface.
TL;DR: A photokeratoscope is described which makes it possible to record in a single photographic exposure the contour of the entire corneal surface of the eye by using a hemispherical object surface located such that its center of curvature coincides with the center of curve of the cornea being photographed.
Journal ArticleDOI
Automatic photoelectric keratometer.
TL;DR: An instrument is described which automatically measures the radius of curvature of the cornea and other spherical surfaces in the form of an electronic signal and the accuracy is comparable to that of an optical keratometer.
