Reducing the risk of refractive surprises. ZEISS IOLMaster 700

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 technological leadership.

Total Keratometry has the potential to reduce refractive surprises to a minimum

Total Keratometry

Measure the posterior corneal surface – new Barrett formulas

Now featuring Total Keratometry (TK®) the ZEISS IOLMaster 700 allows you to directly measure the posterior corneal surface using SWEPT Source OCT.

  • Two exclusive new formulas: Barrett TK Universal II 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

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.

Optimize your cataract workflow

Measure both eyes in less than 45 seconds. Alignment assistance functions make the results largely independent of the user and therefore easy to delegate.1

Achieve a cataract penetration rate of more than 99% and reduce the number of ultrasound cases by 92%, saving you valuable time.2

ZEISS IOLMaster 700 - markerless toric IOL implantation

Precise3 and efficient4 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. Both reference images and keratometry data are transferred to the ZEISS CALLISTO eye® computer-assisted surgery system. Manual marking steps can be skipped for efficient4 and more precise3 toric IOL alignment with reduced residual astigmatism.5
