Precision you can trust for better cataract surgery outcomes.
The ZEISS IOLMaster 500 is a non-contact optical biometer designed for accurate axial length measurement and reliable IOL power calculation. It uses Partial Coherence Interferometry (PCI) technology to deliver precise and repeatable results.
The ZEISS IOLMaster 500 is an advanced optical biometry system developed for modern cataract surgery planning. It measures key eye parameters such as axial length, corneal curvature (keratometry), and anterior chamber depth without touching the eye.
Using Partial Coherence Interferometry (PCI), the device captures highly accurate axial length measurements, even in long or short eyes. Because the system is non-contact, it improves patient comfort and reduces the risk of infection compared to traditional ultrasound biometry.
The IOLMaster 500 also includes built-in IOL calculation formulas, helping surgeons choose the most suitable lens power for each patient. Its intuitive interface and fast measurement process make it ideal for busy eye clinics and hospitals.
With years of clinical validation, the ZEISS IOLMaster 500 remains a gold standard in optical biometry.
Key Features
The ZEISS IOLMaster 500 is widely used in:
It plays a critical role in improving refractive outcomes after cataract surgery.
1. What is the ZEISS IOLMaster 500 used for?
It is used to measure eye parameters before cataract surgery and calculate the correct IOL power.
2. Is the IOLMaster 500 a contact device?
No. It is a non-contact optical biometer, which makes the procedure comfortable.
3. What does it measure?
It measures axial length, corneal curvature (keratometry), and anterior chamber depth.
4. Why is axial length measurement important?
Axial length is the most important factor in calculating accurate IOL power.
5. Can it replace ultrasound biometry?
In most cases, yes. However, very dense cataracts may still require ultrasound.
6. Is it suitable for premium IOL calculations?
Yes. It provides reliable data for toric and multifocal IOL planning.
7. Is the test painful?
No. Since it is non-contact, patients usually feel no discomfort.
8. How long does the measurement take?
The process is fast and usually completed within a few minutes.
