Corneal Tomography in Clinical Practice (Pentacam System): Basics and Clinical Interpretation

Unfortunately this title is no longer available

Salient Features: This edition consists of 7 sections including 24 chapters. It is very rich in information, figures, illustrations, and clinical examples. It follows Sinjab's methodology in the step-by-step systematic approach. It covers: - Clinical basics of corneal optics, geometry, topography and tomography - All profiles, maps and displays of the Pentacam HR including the Belin Ambrosio enhanced ectasia display, Holladay report, and corneal topometry - Clinical basics of wavefront analysis and measurements including Zernike analysis and Fourier analysis - New tomographic definitions and features of ectatic corneal diseases - Grading systems of ectatic corneal diseases including the Belin ABCD keratoconus staging. It is the first book to: - Establish screening guidelines - Present a new systematic interpretation of corneal tomography and practical subjective scoring system - Discuss factors of false positives and false negatives - Address tomographic features of corneas after keratorefractive procedures and after corneal grafts - Study in-depth corneal irregularities using a new 4-selective composite map and new understanding of corneal astigmatism - Address the new concept of corneal refraction and related subjects such as objective corneal dioptric power and astigmatic dissociation - Show the importance of enantiomorphism - Present entities misdiagnosed as ectasia and how to differentiate them from ectasia - Discuss progression criteria of ectatic corneal diseases, corneal tomography and aberrometry in cataract surgery.
