Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study will include 100 eyes of patients aged over 15 years. All patients were subjected to topography imaging.
Using Oculus Pentacam® which is s a rotating Scheimpflug camera. The rotational measuring procedure generates Scheimpflug images in three dimensions.
The scheimpflug principle describes the optical imaging condition when the plane of an object is not parallel to the film of the camera and has to cut each other in one line or one point of intersection with the advantage to achieve wide depth of focus.
Scheimpflug imaging attains a wide and high depth-of-focus , providing sharp images that include information from an anterior corneal surface through to the posterior crystalline capsule; this depends mainly on media transparency and pupil size .
