Replacing assumptions with measurements.

ZEISS IOLMaster 700 with Total Keratometry

ZEISS IOLMaster 700

SWEPT Source OCT biometer

The IOLMaster® 700 from ZEISS with SWEPT Source Biometry® builds upon almost 20 years of experience in optical biometry. Now with Total Keratometry (TK®), it once again demonstrates its technical leadership.

Total Keratometry

Measure the posterior corneal surface

Now featuring Total Keratometry, the IOLMaster 700 from ZEISS allows you to directly measure the posterior corneal surface using SWEPT Source OCT.

  • Two exclusive new formulas*: Barrett TK Universal ll and Barrett TK Toric
  • Can be used in classic IOL calculation formulas
  • No need for a second device, third-party software or an online calculator

*Requires activated Barrett Suite license

Reduce the risk of refractive surprises

Patented Cornea-to-Retina Scan

The patented Cornea-to-Retina Scan shows anatomical details on a longitudinal cut through the entire eye. Thus, unusual eye geometries, such as tilt or decentration of the crystalline lens, can be detected.

Unique Fixation Check

The unique Fixation Check provides you with more confidence in optical biometry. Can you see the foveal pit? If so, you can reduce the risk of refractive surprises due to incorrect measurements caused by undetected poor fixation. If not, you can educate your patients to always fixate on the target.


Visually verify what structure of the eye has been measured

With the patented Cornea-to Retina Scan, complex interpretation of A-scans are no longer necessary. Potential sources of error can be eliminated.

Precise1 and efficient2 markerless toric IOL alignment

The ZEISS IOLMaster 700 is an integral part of the ZEISS Cataract Suite. A reference image is acquired and used for intraoperative matching with the live eye image during cataract surgery. Manual marking steps can be skipped for efficient2 and more precise1 toric IOL alignment with reduced residual astigmatism.3

Are you Ready to Upgrade to TK?

The new IOLMaster 700 TK upgrade is free of charge for ZEISS IOLMaster 700 customers under warranty or service contract. Total Keratometry does not require the Barrett Suite license to operate. Simply choose the option that best describes your current Biometer.

I am an IOLMaster 700 user with Barrett Suite. Please send me software version 1.8 and the Total Keratometry upgrade.

I am interested in trading in my current Biometer for an IOLMaster 700 with all available formulas and the new Total Keratometry license.
