Ziemer Ophthalmic Systems AG
Femtosecond laser-assisted cataract surgery (FLACS) has brought digital precision and predictability to cataract surgery.

CLARIGS

Innovative system for cataract surgery. Premium femtosecond precision that combines Swiss engineering, low energy laser technology, and a compact, efficient design. 

The CLARIGS application (Cataract Laser Advanced Robotic Image-Guided Surgery) integrates intra-operative OCT imaging with smart automation for precise edge detection and cut placement. Using Ziemer’s low-energy femtosecond laser and compact design, it delivers smooth capsulotomies, efficient lens fragmentation, and corneal or arcuate incisions for astigmatism correction - making premium cataract surgery gentler and more accessible.

Benefits at a glance:

  • Gentle, low-energy laser concept – highly efficient & minimizes tissue impact to promote faster recovery. 
  • No intra-operative patient transfer – compact design allows the entire procedure at one workstation, streamlining workflow and improving patient comfort.
  • Automated edge detection & cut placement – reduces variability and enhances surgical precision.
  • Exceptionally smooth capsulotomies – support consistent IOL positioning and refractive outcomes.
  • CE-marked for pediatric cataract surgery – proven safety and effectiveness even in delicate cases.
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.

CLARIGS – Mobile precision in Cataract Surgery

What's different with Ziemer?

As a pioneer in femtosecond lasers, Ziemer combines Swiss engineering, a mobile and compact platform, and a low-energy femtosecond laser concept. This unique approach delivers exceptional refractive outcomes (1)(2)(3)(4)and is designed for minimal tissue impact, reducing side effects and inflammation while supporting fast, predictable visual recovery.

 

Faster Nucleotomy with the FEMTO LDV Z8

Lens Fragmentation

  • Choose between pizza or spiderweb fragmentation patterns to tailor the approach to each patient.
  • The pre-chopped nucleus allows smooth, efficient piece removal with minimal capsule stress for a gentler treatment.
  • Quick lens separation and emulsification optimize phaco time and reduce ultrasound energy, helping preserve corneal health and speed recovery.
  • Only 0.28% intraoperative complications across >1,800 eyes (0.17% anterior tears, 0.11% PCR). (5)
Lens Fragmentation - Create a pizza or spiderweb fragmentation pattern, which enables a customized approach for each patient.

Capsulotomy

  • Laser precision ensures perfectly circular and accurately sized capsulotomies.
  • Intra-operative OCT imaging supports automated or manual centering on the preferred ocular structure.
  • A well-sized and centered capsulotomy creates a 360° overlapping edge, securing IOL stability and minimizing decentration for optimal refractive outcomes.
Laser-assisted cataract surgery allows a perfect circularity and sizing of the capsulotomy

Clear Corneal Incisions (CCI)

  • Individually define the size, geometry, and position of each incision according to the selected IOL.
  • Intra-operative OCT guidance ensures precise cutting and optimal limbal placement for a stable anterior chamber.
  • With the FEMTO Z8, corneal incisions are consistently stable, self-sealing, and reproducible, enhancing surgical safety and outcomes.
Clear Corneal Incisions (CCI) - Define individually the desired size, geometry and position of each incision based on the selected IOL

Arcuate Incisions

  • Intra-operative OCT imaging ensures precise control of depth, angular position, arc length, optical zone, and curvature.
  • Software-guided refractive incisions provide more repeatable and predictable astigmatism correction.
  • With the FEMTO Z8, the procedure is designed to be gentler for patients by preserving 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

Toric Marker

  • With Toric Marker, the FEMTO Z8 provides small intrastromal markings that assist with the alignment of a toric IOL
  • The axis, position and depth can be adjusted with intraoperative OCT
  • Cyclotorsion compensation based on iris matching or ink markings ensures the accurate axis of the Toric Marker

Pediatric Cataract

  • The FEMTO Z8 is the only CE-marked femtosecond laser approved for pediatric cataract surgery.
  • Its compact, mobile design integrates seamlessly into the OR, simplifying workflow and avoiding patient transfer.
  • The largest number of published pediatric cases in peer-reviewed literature have been performed with the FEMTO Z8, underlining its safety and clinical validation. (6)
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.
