The first swept-source Optical Biometry
The TowardPi ® Zalioth SS Optical Biometer

Zalioth enables full visual measurement with higher detection rate and full eye data in multiple direction. Segmented refractive index and two-mode curvature were used to improve data accuracy.

Zalioth also includes EVO and KANE formulas to calculate the whole ocular axis and intraocular lens state, improving calculation accuracy. Customized report templates are available.

The software includes front and rear surface topographic maps, corneal wavefront aberrations, and crystal lens analysis for refractive cataract surgery planning.

Allows you to directly measure the posterior corneal surface using SWEPT Source OCT

The "dynamic panoramic ocular axis imaging" method provides real-time visualization. It monitors fixation and displays macular fovea fixation at the same time. Eye parameters can be obtained at the same eye position, fastens acquisition and improves measurement accuracy and repeatability. Real-time panoramic images from cornea to retina are obtained, the measurement data can be confirmed.

Get fewer refractive surprises: Detect unusual eye geometries & poor fixation, providing a full-length OCT image showing anatomical details of the eye on a longitudinal cut through the entire eye.
Improve your refractive outcomes: Repeatability is essential for good refractive outcomes.
Optimize your workflow : Easy to use, Fast and Delegate, while all the measurements take only seconds. This is a huge advantage – especially with restless patients. Also combines the all well-known Toric IOL Formulas calculation in one powerful tool.

Connection Between Arterial Pressure and Arteriolar Diameter Captured by UWF SS-OCTA

Research recently published in <Ophthalmology Science> investigated the metrics of retinal arterioles and venules based on the en face images of the superficial retina using UWF SS-OCTA and assessed their relationships with specific systemic parameters in a normal sample. Retinal arterioles and venules were manually segmented and distinguished from the disc margin based on 24mm […]

Decreased Choroidal Thickness Associated to Early Neurodegeneration in NDR Detected by UWF Full-Range SS-OCTA

Research recently published in <Retina> identified associations between choroidal alterations and the reduction of peripapillary retinal nerve fiber layer (pRNFL) thickness in diabetes without diabetic retinopathy (nondiabetic retinopathy, NDR) by using UWF SS-OCTA. The results revealed significant reductions in perifoveal ChT (choroidal thickness), CVI (choroidal vascular index) and pRNFL thickness in patients with NDR, while […]

Comparative analysis of a novel spectral-domain OCT biometer versus swept-source OCT or OLCR biometer in healthy pediatric ocular biometry

https://www.nature.com/articles/s41598-024-77177-0 Background Myopia is recognized as a significant global public health concern and a leading cause of visual impairment1. Axial length (AL) elongation is a paramount factor in myopia progression, and measuring AL has been firmly established as a critical assessment in studying the progression and control of myopia. It is widely regarded as the […]
