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

Camera Self-calibration in Scheimpflug Condition for Air Flow Investigation

2006
Camera calibration is a necessary preliminary step to ensure high quality measurement in a section of a flow. The bundle adjustment technique is based on redundancy resulting from multi-viewing the calibration target. In this paper we proposed a well-adapted protocol for self-calibrating a Scheimpflug model.

Quantitative Scheimpflug camera study of the lens density in healthy Turkish population

International Ophthalmology, 2016
The purpose of this study is to evaluate the association between the age and the density of anterior, posterior, and nuclear parts of lens and detect the normal lens density (LD) values in different age groups. 370 eyes of 370 voluntary healthy Turkish subjects were included. These were divided in four groups according to their age. These were Group 1 (
