Topography
Color LED technology
= Spot reflection topography
l Reflection technology is the most acurate way to measure SimK readings
l Highly sensitive to radial and axial displacement
l Unique triangular ray-tracing spot identification pattern design
l Measurement zone 0mm – 10mm l Direct independent instantaneous
measurement of Anterior and Posterior
l Total Corneal Astigmatism / EKR
l Technology customized for Cataract Surgery
l Ocular surface information l IP / USP protected

Traditional Placido disc technology
= Ring reflection topography
l No detection of radial displacement l Ocular Surface sensitive –
disc smearing – confusion of data
l Measurement zone 1mm – 10mm
l Challenge measuring low amount of astigmatism
l Challenge measuring high amounts of irregularity
l Anterior measurements only
l No IP protection, no USP’s
l Mainly used in General clinics / Opticians / Contact Lens fitting
