Oertli OS4 UP

Precision Without Compromise

The Oertli OS4 UP is a next-generation surgical platform engineered for uncompromising performance in both anterior and posterior segment surgery. Designed to deliver exceptional control, fluidics stability and surgical efficiency, the OS4 UP empowers surgeons to operate with confidence — even in the most complex cases.

Elevating Surgical Control

Modern ophthalmic surgery demands precision, stability and adaptability. The OS4 UP combines intelligent fluidics, advanced phaco technology and high-performance vitrectomy into one streamlined system — helping you maintain control from incision to closure.

Key Features & Benefits

1. Dynamic Infusion System

Near-Physiologic IOP Stability

The OS4 UP’s dynamic infusion system continuously adapts to changing intraoperative conditions to maintain stable intraocular pressure (IOP). By responding instantly to fluctuations in flow and aspiration, it:

  • Enhances anterior chamber stability

  • Reduces surge and pressure drops

  • Minimises manual intervention

  • Improves overall surgical safety

The result? Greater predictability and confidence throughout the procedure.

2. Advanced Phaco Control with PACS Technology

Smooth, Intelligent Energy Delivery

At the heart of the OS4 UP lies Oertli’s PACS (Phaco Assisted Cataract Surgery) technology. Designed to provide smooth and consistent phaco performance, it offers multiple modulation modes including:

  • Continuous

  • Pulse

  • Burst

  • PACS mode

PACS functions like cruise control for phaco — automatically optimising energy delivery for efficient nucleus management while protecting delicate ocular structures. Whether tackling routine cases or dense cataracts, the OS4 UP ensures refined control and efficiency.

3. Caliburn Trocar System

Effortless Entry, Reliable Stability

The Caliburn Trocar System is engineered for precision and ease of use. Its sharp, lance-shaped blade and bevelled cannula design:

  • Reduces penetration force

  • Enables smoother insertion

  • Provides stable wound architecture

  • Supports consistent sclerotomy performance

This refined trocar design enhances workflow and surgeon comfort during vitreoretinal procedures.

4. Continuous Flow Cutter

High-Performance Vitrectomy

The OS4 UP features a Continuous Flow Cutter capable of delivering high cut rates with uninterrupted aspiration flow. Benefits include:

  • Up to 15,000 cuts per minute

  • Improved aspiration efficiency

  • Reduced vitreoretinal traction

  • Smoother, faster tissue removal

By maintaining continuous flow, the cutter enhances safety and procedural efficiency — particularly in complex posterior segment cases.

Designed for Versatility

From cataract surgery to advanced vitreoretinal procedures, the OS4 UP adapts to your surgical demands. Its modular design allows seamless transitions between anterior and posterior applications, making it a powerful all-in-one solution for modern surgical practices.

Built Around the Surgeon

The OS4 UP is engineered with intuitive controls, ergonomic design and streamlined workflow integration — helping surgical teams operate more efficiently while maintaining the highest standards of care.
