Tab Article

This edition consists of 7 sections, including 26 chapters. It is very rich in information, figures, illustrations, and clinical examples. It follows Sinjab's methodology in a step-by-step systematic approach.

It covers:

• Clinical basics of corneal optics and geometry.

• Clinical basics of 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 grading.

• How to apply corneal tomography for laser-based and lens-based refractive surgery?

• How to apply corneal tomography to modern cataract surgery?

It is the first book to:

• Establish screening guidelines.

• Present a new systematic interpretation of corneal topography.

• Present a new practical subjective scoring system, the Sinjab's PS3 algorithm.

• Present a new algorithm for best IOL selection in lens-based and modern cataract surgery, Sinjab's PSIS algorithm.

• Discuss the 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.

• Present a new understanding of corneal astigmatism.

• Address the new concept of corneal refraction and related subjects such as objective corneal dioptric power and astigmatic disparity.

• Show the importance of enantiomorphism.

• Present entities misdiagnosed as ectasia and how to differentiate them from ectasia.

• Discuss the progression criteria of ectatic corneal diseases.

• Apply a detailed corneal tomography for cataract surgery.
