Replacing assumptions with measurements.

ZEISS IOLMaster 700 with Total Keratometry

Watch and see why Total Keratometry is a real breakthrough

Extra – exclusive NEW Barrett formulas

The current keratometry standard in IOL power calculation is to only measure the anterior corneal surface and then estimate the total corneal power using model eye assumptions or nomograms. However, this method does not address outliers in cases of unusual corneas, which could result in refractive surprises.

With a software update due for release in 2018, the ZEISS IOLMaster 700 with SWEPT Source OCT technology allows you to directly measure the posterior corneal surface. It combines unique telecentric keratometry measurement of the anterior corneal surface with measurement of the posterior corneal surface in order to calculate Total Keratometry (TK®).

Total Keratometry has the potential to reduce refractive surprises to a minimum.
