Corneal topography: A new photokeratoscope [PDF]

Eye, 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 ...

Topography-Guided Custom Ablation Treatment for Post-Traumatic Corneal Irregularities—Case Reports

Biomedicines
Background: Post-traumatic corneal wounds that require suturing are quite common; they reduce corneal transparency and cause corneal distortion, leading to corneal astigmatism and higher-order aberrations.

Corneal topography with an aberrometry-topography system [PDF]

Contact 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 ...
