Sophi, the first battery driven phaco system operates fully without any disturbing connection cables and is equipped with an integrated air compressor.
The simple and ergonomic design offers excellent support to the surgical team. Innovative assistance features facilitate ease of handling.
Sophi’s pioneering and smart design of consumables leads to high functionality and economic benefits.
Sophi benefits the whole team. It is designed to bring mobility, simplicity and safety to a new level.
This is the idea behind Sophi. We have redefined the requirements of a perfect Phaco-System by focusing on the points of view of the surgeon, the surgical team and all other involved parties. The result is a high-end device which sets new standards.
Sophi is the first wireless Phaco-System to offer the surgical team high flexibility and mobility. This means ease of handling in the operating room and increased usability.
Sophi’s design is simple and straightforward. The complexity is inside the device, which allows for simple user handling, helps to save time and increases productivity.
Sophi opens up new avenues in hygiene and safety. The Clean Venturi and automated Cassette Slot-In-System reduce the risk of contamination. The IOP Control Pump is designed for high chamber stability.
Altogether, the benefits of Sophi’s 3-Pillar-Concept facilitate simpler, safer and faster operating procedures – before, during and after surgery. This significantly increases efficiency and therefore also yields economic benefits.
Set up, operate, rearrange – again and again. One wants a device which can be moved easily and conveniently. We have used the possibilities of modern technology, and freed Sophi of disturbing cables and tubes. This revolutionary step gives you more flexibility and constitutes a crucial workflow improvement in the operating room.

The first battery-powered Phaco-System
With Sophi not only the foot pedal works without cables, but the entire device. It requires neither a power cable nor data cables. Sophi is mobile and it is exactly this mobility which simplifies your work and therefore improves efficiency.
Integrated compressor
The compressors for vitrectomy and for Clean Venturi aspiration are also integrated into the device. Therefore, the usual bulky and inflexible tube to the external compressor becomes superfluous.
Freedom thanks to mobility
Sophi is incredibly adaptable. The 180° rotatable display and freedom to choose the tray position facilitates setting up the operating room. Moving the device is very simple too: Release Mono-Brake Handle, move Sophi to the desired location, apply the brake – done.
Ready for the future
These days a wireless connection of the foot pedal over Bluetooth is standard. However, Sophi can do much more! Sophi enables you to transmit live microscope images to the display over Wi-Fi.
The basis of the Easy-Move Concept is the elimination of both the power cable and pneumatic tube during device use. This is enabled by a high-power battery, which feeds the device with energy throughout the day.
A simple hand movement suffices to lock or release all four wheels. The integrated ergonomic handle located around the device allows for the flexible movement of Sophi from all sides.
Thanks to the flexible arrangement options of the display and tray, you can adapt the set-up of the device to your individual requirements.
Countless other set-ups possible thanks to the 180° rotatable display and the adjustable tray.
Sophi makes it easy for you – including the charging of the foot pedal. After a day of surgery, you simply attach the foot pedal to the charging station, which automatically charges the battery by induction – with neither cable nor sensitive contacts.
Sophi’s foot pedal comes with integrated LED lighting, which enables you to accurately move the foot pedal under the surgical table. Easy Move has a further benefit: You can move the foot pedal over the floor like a hovercraft.
Sophi also assists with the communication between surgeon and assistant. The video is transmitted to the display, which enables the assistant to follow the surgeon’s work in real time. Therefore, the assistant is kept informed throughout the surgery, and is more mobile, as looking through the microscope is unnecessary.
The surgical team should be able to focus entirely on the surgery. Sophi assists you to do just this. Modern assistance systems and clever control elements create a simple surgery process. Sophi can be parametrized intuitively, assists you with intelligent sensor technology, and automatically adjusts parameters in critical situations automatically.

This AG was founded in 2014 as a start-up high-tech company comprising proven experts who have significant knowledge and practical experience in industrial medical R&D and production. The name “This” stands for “Think in System” and reflects both our mindset and the way we design and produce ophthalmic systems: systematically, logically and holistically.
The design and development time of our first medical device – from day one until market launch at ESCRS 2018 in Vienna – lasted 4 years. Along with the design of Sophi, the structure and processes of the company This AG were built and enhanced continuously.
After only 4 years a whole collection of prototypes exists. The development stages of Sophi can be comprehended with these prototypes. Particularly the pumping system and the cassette were built as prototypes at early development stages.
Only joy and pleasure behind one’s work make such projects possible. That was indeed the case with Sophi. This AG offers an environment that encourages creativity and promotes and challenges individual strengths.
When we at “This” speak of thinking in terms of systems, we refer not only to the system of the device, but also to everyone working with that device in the field. Learning from surgeons and surgical teams, our engineers, customer service and sales teams have the desire to know and understand each work process around our device in detail, which enables them to drive innovation and optimization forward.
This AG is not only responsible for the design, but also for the manufacture, license and sale to local distributors worldwide. As an end-user, you can benefit from a knowledgeable distributor near you.
The Sophi brand comprises three words which get to the heart of our ambition with regard to quality and innovation: swiss ophthalmology innovation. Sophi is an entire new design with numerous ideas and solutions which are unique in their implementation and combination. With “This AG” we generated a platform for realizing new revolutionary ideas.
A complex and yet indispensable component of This AG is the quality management system. Since December 2018 This AG is EN ISO 13485:2016 certified for the design, the production, the distribution and the service of medical devices for ophthalmic surgery.
