Z-CATARACT / Ziemer Ophthalmic Systems AG

The Z-CATARACT application uses intra-operative OCT imaging and machine learning algorithms for automated edge detections and cut placements. It offers capsulotomies with exceptionally smooth edges, very efficient lens fragmentation and amongst clear corneal incisions, also the possibility of arcuate incisions for the correction of astigmatism.

Benefits at a glance:

Automated edge detection and cut placements
Capsulotomies with exceptionally smooth edges
Very efficient lens fragmentation
Optimized phaco time and reduced energy
No intra-operative patient transfer needed
CE marked for Pediatric Cataract surgery

What's different with Ziemer?

As a pioneer in low energy femtosecond laser treatments, Ziemer’s low energy concept provides maximal precision, minimal tissue damage, minimal side effects, and less inflammatory response and is known to contribute to fast visual recovery.

Faster Nucleotomy with the FEMTO LDV Z8

Lens Fragmentation

Create a pizza or spiderweb fragmentation pattern, which enables a customized approach for each patient
The pre-chopped nucleus allows smooth and efficient removal of the pieces with minimal stress to the capsule, making it a gentle treatment
The quick and easy separation and emulsification of the lens optimizes phaco-time and reduces energy

Capsulotomy

Laser-assisted cataract surgery allows perfect circularity and sizing of the capsulotomy
Intra-operative OCT imaging enables the physician to automatically or manually center the capsulotomy to the preferred ocular structure
Properly sized and centered capsulotomy provides a 360-degree overlapping edge and provides optic decentration of the IOL in the capsular bag after implentation

Clear Corneal Incisions (CCI)

Determine individually the desired size, geometry and position of each incision based on the selected IOL
The precise cutting performance and optimal positioning at the limbus based on intra-operative OCT imaging ensure a stable interior chamber
With the FEMTO Z8, clear corneal incisions are more stable, self-sealed and reproducible

Arcuate Incisions

Intra-operative OCT imaging provides precision and control in depth, angular position, accurate arc length, optical zone and continuous curvature of the arcuate incisions
Software-controlled refractive incisions for astigmatism correction offer more repeatable and predictable refractive results
With the FEMTO Z8, the arcuate incision procedure is more gentle on the patient by sparing the corneal epithelium

Arcuate Incisions - Intra-operative OCT imaging provides precision and control in depth, angular position, accurate arc length, optical zone and continuous curvature of the arcuate incisions

Pediatric Cataract

The FEMTO Z8 is the only CE-marked laser approved for pediatric cataract surgery
A seamless workflow integration is ensured thanks to the mobility and small footprint of the FEMTO Z8
Largest number of cases published in peer-reviewed literature so far are with the FEMTO Z8¹
