Conditions

The Reliability of Corneal Topographic Measurements of Keratoconus Eyes

Brief summary

The purpose of current study is to provide a comprehensive comparison of the reliability of corneal topographic measurements between Optovue AS- OCT and a combined Scheimpflug imaging using Wavelight Oculyzer Pentacam HR in normal and keratoconus eyes.

Interventions

DIAGNOSTIC_TESTcorneal topography

In all patients, TCT will be measured first by WaveLight® Oculyzer™II Pentacam HR and second by The Optovue AS-OCT .
