CATALYS Femtosecond Laser
Designed specifically for laser cataract surgery, the CATALYS System offers:
- Liquid Optics Interface, gentle docking with minimal intraocular pressure rise and clear optics for excellent imaging and laser delivery
- Integral Guidance System- proprietary 3D Full Volume Optical Coherence Tomography (OCT) and automated surface mapping algorithms that guide laser delivery
- Precise capsulotomies within 30um
- Complete segmentation and softening of the cataract with adjustable grid sizing
- Multiple corneal incision centration options that are based on anatomical landmarks
The CATALYS Precision Laser System combines a <600 femtosecond laser, gentle LIQUID OPTICS interface, and integrated 3D Full Volume Optical Coherence Tomography (OCT) image-guidance system to create precise incisions in the lens and cornea. The CATALYS System was developed in close collaboration with a medical advisory board of cataract experts from around the world. In 2012, the b System was recognized as one of the top 100 technological innovations in the world. Throughout the development of the CATALYS System, numerous technology choices were made aimed at delivering excellent precision. Two of the most critical components are the patient docking interface and the image-guidance system. The LIQUID OPTICS Interface is designed to provide a stable, gentle dock and a clear optical path for the OCT and laser.
In addition, the CATALYS System is equipped with INTEGRAL GUIDANCE System, an image-guidance system which maps ocular surfaces, establishes safety zones allowing the physician to select and customize the treatment, ensuring that the femtosecond laser pulses are delivered precisely to the intended location.
Understanding the user experience is another critical area focus for the CATALYS System development team. The system’s intuitive and ergonomically designed controls were developed with the needs of the patient, surgeon, technicians and nurses in mind. A Medical Advisory Board of cataract experts and Medical Staff Advisory Board of dedicated technicians and nurses have had extensive input in the system design and usability.
The CATALYS System procedure consists of four steps:
The CATALYS System includes design features that optimize the precision, safety and control of all four steps of the procedure.
LIQUID OPTICS INTERFACE
The novel two-piece liquid interface docks the patient to the system and is designed to provide:
A clear optical path for real-time video, OCT imaging, and laser treatment by:
- Filling in corneal surface irregularities with liquid
- Creating a wide field of view, enabling all cuts to be performed in a single dock
A gentle dock for the patient by:
- Minimizing the rise in intraocular pressure, which is particularly important for older cataract patients and those with glaucoma
- Minimizing scleral contact of the interface with minimal redness of the eye after surgery
INTEGRAL GUIDANCE System
During the CATALYS System procedure, the ocular surfaces are visualized by a proprietary, integrated Optical Coherence Tomography (OCT) system. The OCT is enhanced by sophisticated algorithms designed to ensure that the femtosecond laser pulses are delivered precisely to the intended location.
Steps in the INTEGRAL GUIDANCE System process:
- Proprietary, 3D spectral-domain OCT imaging system visualizes the ocular surfaces
- Algorithms process the image, automatically and accurately maps surfaces and create safety zones
- The surgeon’s treatment plan is then customized, based on the patient’s ocular anatomy and the precise orientation of the eye
- After the surgeon confirms the customized treatment plan, the femtosecond laser pulses are delivered precisely to the intended location, maintaining the safety zones
