Corneal Tomography in Clinical Practice (Pentacam System) (3^rd Ed.)
Basics & Clinical Interpretation

Corneal tomography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. This procedure may be carried out with a Pentacam, which uses a rotating camera to create a 3D image of the anterior of the eye.

This third edition has been fully updated to provide the latest developments in corneal tomography using the Pentacam system.

Beginning with an introduction, the following sections cover corneal maps and profiles, corneal refraction, Wavefront analysis, systematic interpretation of corneal tomography, and corneal tomography in ectatic corneal diseases.

The final section explains the Holladay Report, and corneal tomography and aberrometry in cataract surgery.

Presented in a step by step format the new edition of this popular manual also includes discussion on false positives and false negatives.

Authored by recognised expert Mazen M Sinjab, the book features nearly 350 high quality, colour images and illustrations.
