10 years of clinical experience result in IOL calculations
surgeons can trust.
The IOLMaster 500 offers a wide range of on-board IOL calculation options, including the fourthgeneration Haigis formula and convenient data export to the Holladay IOL Consultant software.
For patients with prior laser vision correction (LVC), IOL selection can be a challenge. In its post-LVC calculation toolbox, the IOLMaster 500 includes the Haigis-L formula, which requires no clinical history data.1
Any intraocular lens calculation is only as reliable as the lens constants it is based on. The long clinical experience with the IOLMaster is reflected by the Users’ Group for Interference Biometry (ULIB) website. For virtually all common IOL types, the ULIB database contains lens constants optimized specifically for the IOLMaster. And the IOLMaster 500 allows these constants to be further refined and personalized.
