Self-calibration of Scheimpflug cameras: an easy protocol

Measurement Science and Technology, 2007
The problem of the self-calibration of Scheimpflug cameras is addressed. The approach aims to calibrate by handpositioning a roughly-known calibration pattern, thanks to a bundle adjustment technique. The purpose of this paper is to design an easy protocol accordingly.

Evaluating Cataract Development with the Scheimpflug Camera

1990
Documentation of pathologic findings in the lens over a prolonged period is rather difficult. Until recently, only written reports or drawings of the process have been employed. Photography with the slit-lamp microscope has not been effective because of the insufficient depth of field and the poor reproduction capacity of instrumental parameters ...

Scheimpflug camera changes after cross-linking for keratoconus

Menoufia Medical Journal, 2015
Objectives The aim of our study was to evaluate corneal changes after corneal collagen cross-linking (CXL) in progressive keratoconus with Pentacam Scheimpflug imaging. Background Corneal collagen CXL using ultraviolet A light and riboflavin was introduced as a method to halt the progression of keratoconus. Scheimpflug imaging is considered among
