ZEISS IOLMaster 700 with Central Topography

Also new: Barrett True K with TK

For improved outcome predictions

The ZEISS IOLMaster 700 now not only features Central Topography but also the new Barrett True K with TK formula. A recent study conducted by Michael Lawless, James Y. Jiang, Chris Hodge, Gerard Sutton, Timothy V. Robert and Graham Barrett found that in post-myopic LASIK eyes the Barrett True K formula with TK improved the outcome predictions compared to the Barrett True K with Classic Ks within ±0.5 D by >12 % (p = 0.04)1.
