Placido VS Scheimpflug

Placido disc is used to project a set of concentric rings on cornea surface, then the shape of corneal surface can be characterized by assessing the refection of rings off the anterior corneal surface and the cornea curvature and the cornea power will be calculated from the data of thousands of points on the rings.

What is Wavefront Aberration?

Each beam contains a sinusoidal oscillation, and points in the entire sinusoidal oscillation array having the same phase direction form a refractive surface that is perpendicular to the plane wavefront of the propagation direction.

A New Intraocular Lens Power Formula Integrating an Artificial Intelligence–Powered Estimation for Effective Lens Position Based on Chinese Eyes

To develop and evaluate a new intraocular lens (IOL) formula based on Chinese eyes.

Comparison of a Scheimpflug imaging with other screening indices in diagnosing keratoconus and keratoconus suspect

We aimed to evaluate the diagnostic ability of a Scheimpflug imaging device (Scansys) for KC and KCS and compared it with other Scheimpflug-based devices (Pentacam and Corvis ST).

Comparison of a New Scheimpflug Camera and Swept-Source Optical Coherence Tomographer for Measurements of Anterior Segment Parameters

This study evaluated the differences and agreement between a new Scheimpflug camera (Scansys) and a swept-source anterior segment optical coherence tomographer (CASIA 2) for measurements of the anterior segment of the eye in normal subjects.
