OPTICAL BIOMETRY (ZEISS IOL MASTER 700)

Optical Biometry using the Zeiss IOL Master 700 is a non-contact diagnostic imaging service that measures the eye with high precision before cataract and refractive lens surgery. It uses advanced swept-source optical coherence technology to capture detailed axial and anatomical data. As a result, your ophthalmologist can select the most accurate intraocular lens power and improve surgical planning.

WHAT THIS SERVICE MEASURES

This test measures the key dimensions that guide lens implant calculations. It captures axial length, corneal curvature, anterior chamber depth, and lens thickness. In addition, it evaluates central corneal parameters used in modern formulas. Therefore, it supports more reliable intraocular lens selection and refractive outcome prediction.

The Zeiss IOL Master 700 also provides cross-sectional signal checks along the visual axis. Consequently, doctors can confirm measurement quality and detect fixation or media issues early.

WHEN DOCTORS RECOMMEND OPTICAL BIOMETRY

Doctors request this scan as a core step before lens-based surgery. For example, it is standard in modern cataract workflows.

1. Cataract surgery lens power calculation
2. Refractive lens exchange planning
3. Premium and toric lens selection
4. Post-refractive surgery lens planning support
5. Baseline axial length documentation

HOW THE TEST IS PERFORMED

The procedure is fast and completely non-contact. First, you sit at the device and place your chin on the support. Next, you focus on a fixation target while the system captures measurements within seconds. During the scan, nothing touches the eye. Therefore, the test remains comfortable and infection risk stays low.

Most sessions finish within a few minutes. In many cases, dilation is not required unless combined with other diagnostics.

PATIENT COMFORT AND SAFETY

The Zeiss IOL Master 700 uses safe light-based technology and does not require injections or eye contact. Most patients complete the test easily. Moreover, normal activities can resume right after measurement. However, very dense cataracts may sometimes reduce signal quality and require alternate methods.

WHY PRECISE BIOMETRY MATTERS

Accurate measurements directly affect lens power selection and visual outcome. For instance, small axial length errors can lead to refractive surprise after surgery. Therefore, high-resolution optical biometry improves predictability. In addition, modern formulas perform better when fed with precise data.
