EYESTAR 900 is a device developed by Haag-Streit which utilises 3D OCT for quantitative measurements of the geometry of the entire eye, including ocular biometry and corneal topography. It is the most recent in a series of successful biometry devices by Haag-Streit (HS Pachymeter, Lenstar LS 900, LS 900 T-cone and LS 900 APS) and also allows for advanced corneal tomography examinations. The EYESTAR 900 is CE marked. These measurement results of this device are used for the planning of the medical treatment of patients. Depending on the application, the benefits of this device may include improved visual acuity (after cataract surgery), reduced risk of complications (after refractive surgery or implant of a phakic intraocular lens), early identification of pathological deformations of the cornea (keratoconus detection). The primary objective of this clinical trial is to assess the clinical performance of the investigational device in dense cataracts. To that end, for each measurand, the in-vivo repeatability will be quantified, as well as limits of agreement and the mean measurement deviation, with respect to the current gold standard device. As a secondary objective of the study, raw measurement data will be collected to allow for the improvement of existing algorithms, development of additional measurands and for retrospective analysis. No diseases are studied.
