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.
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.

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.

Topographic indices sim K, steep K, Kmax and pachy thin were analyzed on a dual scheimpflugh corneal topography
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.
