Title

Topographical signs of astigmatism

Purpose	Analysis of astigmatism using different measuring devices and learn how to make a correct analysis
Methods	Different devices for analysis of astigmatism will be highlighted: manual and automatic keratometry, corneal topography, Scheimpflug images of the cornea and internal ocular astigmatism as well as wavefront images of the whole eye.
Results	Each of these devices help us to have a clearer image of degree and origin of the astigmatism. This might influence our therapeutic approach in cataract, refractive surgery or in prescribing corrective lenses. Classic astigmatism as well as pitfalls in diagnosis of astigmatism will be shown.
Conclusion	Different measurement techniques help us to grade the astigmatism and help us in our therapeutic approach.
