ZEISS EQ Workplace
Software designed to save time during pre-operative processes, protect against never-events, and access data from anywhere.
- ZEISS IOLMaster data is transferred automatically to the ZEISS EQ Workplace, to populate the relevant fields for toric IOL calculation and selection
- Integrated toric formulas: Barrett TK Toric, Barrett Toric, Z CALC 2.0 and Haigis T
- Pre-plan your surgery remotely: Connect to your ZEISS CALLISTO eye and prepare your surgical assistance functions.
- Direct online ordering of IOLs in selected countries

Z CALC
The Z CALC online calculator is a free browser-based web application that supports users in selecting ZEISS toric IOLs.
- Specifically for ZEISS IOLs optimized proprietary calculation algorithm predicting the post-operative residual refraction
- Takes posterior corneal astigmatism into account – either by using ZEISS IOLMaster TK values or with the Z CALC nomogram
- Allows for adjustment of estimated lens position (ELP)
- Enables quick and easy ZEISS IOL ordering (in selected countries)
