The Catalys system recently underwent a software upgrade to version cOS 3, which served to strengthen the existing functionality while improving workflow.
The biggest upgrade is the addition of streaming OCT, which is of particular benefit to detect eye movement during the incision stage. Aided by an internal guidance system, the cOS 3 upgrade reduces the time needed for incision computation and requires fewer operator adjustments and modifications to the baseline protocols.
The usability of the system with the cOS 3 upgrade is enhanced by the addition of several automated treatment plans, including an option to align the capsulotomy over the scanned capsule using the live OCT feature. The wealth of additions is not overwhelming, however, and the system can be easily integrated for use in all types of cases, from routine to complex. The capsulotomy is performed in less than 1 second with minimal cavitation bubbles and even dense, grade 4 cataracts can be fully fragmented with the laser.
The docking process has also been enhanced in an effort to reduce residual forces during the “lock” step. This feature has implications for reducing micromovements of the eye during the procedure to minimise the risk of capsule tears. These additions add to the already innovative and validated liquid optics interface, which induces minimal changes in IOP and no corneal folds, thereby yielding a clear optical path for laser delivery.
What these upgrades add to an already innovative platform is an increased chance to achieve superior clinical outcomes precisely, consistently and predictably. I have found the cOS 3 upgrade easy to integrate and having it available is a tremendous benefit when I am implanting a premium IOL for which the accuracy of each step is crucial.
When I am able to deliver on the results promised to my patients after surgery, it yields a premium experience, whereby the surgeon can feel satisfied with the result and patients go home happy with their new postsurgical vision.
