Drawing from his own experience and that of others as well as the scientific and technical literature, he covers fundamentals of
corneal topography using the Pentacam tomography technology, functional description, ectatic corneal diseases, points affecting the decision, and miscellaneous topics.
Corneal topography to assess progressive corneal ectasia
Incidence and characteristics of unilateral keratoconus classified on
corneal topography. J Refract Surg.
Exclusion criteria were patients younger than 18 years old, unstable hyperopia, presence of active corneal disease, uveitis, anterior or posterior synechiae, glaucoma or ocular hypertension, history of ocular trauma, previous intraocular or corneal surgery, retouch of refractive surgery, irregular cornea on
corneal topography, and preoperative mean keratometry outside the range of 39.00 to 46.00 D; patients with amblyopia and a potential CDVA of less than 0.4 on the decimal visual acuity scale (20/50) were also excluded.
Before the CXL treatment, all the patients underwent full ophthalmic examination and
corneal topography. Topographic analysis was obtained through Pentacam (Oculus Optikgerate, Wetzlar, Germany).
Videokeratography was performed with Atlas Model 9000
Corneal Topography System, from Carl Zeiss Meditec Inc (USA).
bring together a group of ophthalmologists and individuals working in artificial intelligence and corneal analysis in Brazil, the US, India, Dubai, Asia, and Germany for 18 chapters on the use of elevation based
corneal topography or tomography to look at the cornea, its structure, shape, and performance, with a focus on the OCULUS Pentacam system.

Corneal topography: contact lens considerations Nick Howard and Emily Searle
The patients underwent preoperative and postoperative examination including ophthalmologic examination,
corneal topography using two different technologies, the GALILEI-Dual Scheimpflug Analyzer (Ziemer Group AG, Switzerland) and the Wavelight Allegro Topolyzer (Alcon Laboratories, Inc., Fort Worth, TX, USA), and ORA measurement.

corneal topography and tomography: a review," Clinical and Experimental Ophthalmology, vol.
Topographic indices sim K, steep K, Kmax and pachy thin were analyzed on a dual scheimpflugh
corneal topography (Galilie G4).
CXL also procures a series of corneal issue alterations which have been described by in vivo corneal confocal microscopy studies these, extensive structural changes have been linked with
corneal topography and pachymetric modifications.
