Zeiss IOL Master 5.4 — Used Optical Biometer
The Zeiss IOL Master 5.4 is an optical biometer that pairs non-contact Partial Coherence Interferometry (PCI) for axial length with 6-point telecentric keratometry for corneal curvature. PCI delivers results compatible with immersion ultrasound at 0.01 mm resolution and no patient contact. In a single session it measures axial length (14–40 mm), corneal radii, anterior chamber depth, and white-to-white, and supports Haigis, Haigis-L, Hoffer Q, Holladay, SRK II, and SRK/T — including post-refractive-surgery calculations via Haigis-L.
The IOL Master 5.4 streamlines pre-operative cataract workflow by completing every required biometric parameter in one non-contact examination. A joystick-controlled alignment system with automatic right/left eye detection keeps operation simple, and the integrated printer provides immediate printed results at the point of care. It is a cost-effective entry into trusted ZEISS optical biometry.
The National Library of Medicine documents that the ZEISS IOLMaster-500 delivers intraocular lens power prediction accuracy on par with other modern optical biometers in cataract surgical planning.
Why Practices Choose the Zeiss IOL Master 5.4
- Non-contact PCI axial length — immersion-ultrasound-compatible accuracy at 0.01 mm resolution with no corneal contact
- 6-point telecentric keratometry — distance-independent corneal power measurement for reliable, repeatable K values
- Haigis-L for post-refractive eyes — accurate IOL power in post-LASIK, PRK, and LASEK patients
- Full IOL formula suite — Haigis, Hoffer Q, Holladay, SRK II, and SRK/T built in
- Automatic right/left eye detection — joystick alignment that simplifies bilateral measurement
- Integrated printer — immediate chairside printout with no external PC
- Cost-effective ZEISS biometry — the most accessible way into the proven ZEISS optical-biometry workflow
