Corneal topography by keratometry [PDF]

open access: bronzeBritish Journal of Ophthalmology, 2000
To investigate the ability of a telecentric keratometer to describe the asphericity and curvature of convex ellipsoidal surfaces and human corneas.22 conicoidal convex surfaces and 30 human corneas were examined by conventional keratometry. Additional keratometric measurements were made when the surface was tilted in the horizontal plane relative to ...

Corneal topography: A new photokeratoscope [PDF]

open access: bronzeEye, 1989
The assessment of the topography of the cornea is an important modality in the management of surgical procedures complicated by astigmatism. Additionally, the outcome of corneal refractive surgery is often best illustrated by photokeratoscopy. Currently available photokeratoscopes suffer from a number of deficiencies that include (i) the lack of ...

Corneal topography with an aberrometry-topography system [PDF]

open access: greenContact Lens and Anterior Eye, 2018
To investigate the agreement between the central corneal radii and corneal eccentricity measurements generated by the new Wave Analyzer 700 Medica (WAV) compared to the Keratograph 4 (KER) and to test the repeatability of the instruments.20 subjects (10 male, mean age 29.1 years, range 21-50 years) were recruited from the students and staff of the ...
