IOLMaster 500
Confidence in picking the right formula
Knowing which IOL formula works best is not always trivial. To help choose the right one, the IOLMaster 500 automatically marks the set of appropriate formulas for a given axial length, based on recommendations in the scientific literature.5


Optimized constants for optimum outcomes
With lens constants for more than 160 IOL types, based on over 30,000 sets of patient data from about 200 clinical sites,6
the ULIB database is an indispensable resource and reflects more than 10 years of clinical experience.7

Further refining lens constants is a key ingredient of refractive predictability. The IOLMaster 500 allows further refining of IOL constants based on individual post-operative data.


No history? No problem!
The number of cataract patients with prior LASIK, LASEK or PRK is growing rapidly. Even if no clinical history data is available, the on-board Haigis-L formula greatly simplifies IOL power calculation in these cases.

Calculation of phakic intraocular lenses is another growing need. A database of anterior and posterior phakic IOL types makes the selection of the appropriate dioptric power straightforward.
