The rate of laser refractive corneal surgery incredibly increased over the last two decades. Thus, the need to understand corneal imaging and how to evaluate candidates of LASIK become a crucial step to avoid long-term complications. This book aims to illustrate how to interpret the corneal tomography printout «Pentacam Corneal Tomography» with detailed case-based examples for better clinical correlation. I ... Read more

Abstract Purpose: To assess anterior segment parameters of keratoconus (KC) eyes at different stages of the disease using Scheimpflug-placido topography (Sirius, CSO, Italy) in a sample of the southern Egyptian population. Methods: retrospective study of 400eyes of different grades of keratoconus along with 50 normal eyes as a control group were assessed for the following parameters: corneal thickness at apex ...

To evaluate the agreement and interchangeability between IOLMaster and Pentacam in phakic intraocular lens (IOL) calculations. METHODS: This was a prospective study involving measurement of the anterior segment parameters anterior chamber depth (ACD), white to white (WTW) line, and average anterior corneal curvature (K-reading) on 108 healthy eyes of 56 consecutive patients. Interdevice agreement and interchangeability in phakic IOL calculations ... Read more

Conclusions: There is a good agreement in ACD and K-readings between Pentacam and IOLMaster, making them interchangeable in biometry and phakic IOL power calculation, but they are not interchangeable regarding WTW line measurement; the difference will affect the phakic IOL diameter, which would affect lens safety.
