Femtosecond laser assisted cataract surgery offers a reproducible, noninvasive technique to replace the least predictable and most technically demanding steps of conventional cataract procedures.
Catalys has two components which are the patient docking interface and the image-guidance system.
Liquid Optics™ Interface
The novel 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
Minimizing scleral contact of the interface with less redness of the eye after surgery
Integral Guidance™ (INTEGRated ALgorithms)
In the Catalys 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 process
• Proprietary, 3D Fourier-domain OCT imaging system visualizes the ocular surfaces
• Algorithms process the image, automatically and accurately detect 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 is
delivered precisely to the intended location, maintaining the safety zones
