ABSTRACT
Topography and keratometry measurement devices lack the additional information of the posterior surface of the cornea and therefore have to estimate this posterior surface. However, their advantage is the stability of measurements and high resolution. Scheimpflug measures the anterior and posterior surface of the cornea, but the measurement time is relatively long and motion artefacts are quite common. Although still expensive, optical coherence tomography technology showed to be highly reproducible and predictive for (toric) intraocular lens power calculation. For toric intraocular lens power calculation it is recommended to use at least two different techniques to measure the cornea and to compare these measurements.
