IOLMASTER 700 Central Topography Workflow Study.
Study Details
Study Description
Brief Summary
The use of ocular biometers like IOLMaster 700, is a common practice to identify several ocular parameters such as the keratometry of the cornea and the axial length of the eye, which are necessary for calculating the power of the intraocular lens in cataract surgery. However, the additional use of other devices, such as Cassini and Pentacam is used to obtain more information of the central topography of the eye. Recently, a new version of the IOLMaster 700 equipment that provides much more detailed information than in its previous version has been presented. The objective of this study is to measure the time that the new IOLMaster 700 takes to perform these measurements of the central topography and compare it with the time it takes using the central topography using the standard IOLMaster 700 version with Cassini on one hand and Pentacam on the other.
It is hypothesized that the use of the new version of the IOLMaster 700 equipment alone can reduce the time of measurements and improve the clinic workflow.
