Medical Design for Ophthalmic Surgery – Geuder VIVOS
How Eckstein Design translated the complexity of ophthalmic surgery into a calm, usable design language for Geuder VIVOS. A medical design project.
Geuder
VIVOS
Ophthalmic surgery platform for anterior and posterior segment

Overview
VIVOS is Geuder's integrated device platform for eye surgery. Three configuration levels share one design language, one user interface and one accessory system, the design answer to a highly complex technical challenge.

The Challenge
A platform that combines anterior and posterior segment, vitrectomy, endoillumination and laser therapy in a single device carries an enormous functional density. This is exactly where the design task begins: that density must not arrive as visual noise in the operating room. Despite numerous ports, modes and configuration levels, the system had to remain immediately intelligible, explain itself to changing surgical teams and embody the manufacturer's ambition at first glance.

The Design Approach
Through industrial design, we translated the technical complexity into a calm, vertical architecture. The free-standing silhouette on a narrow footprint makes the system placeable and movable in a crowded operating room. The floating monitor and the clearly structured port panel arrange the functions hierarchically rather than lining them up side by side. Reduced detailing, high-quality surfaces and a consistent material language give the device a valuable, orienting presence. Design as a visible promise of quality.


Design Language
A calm vertical architecture consolidates a wide range of functions into a clear silhouette. Reduced details and high-quality surfaces give the system a valuable, unobtrusive presence in the operating room.
Operation & UI
Monitor, control bar and port panel are structured so that users find their way without instruction. A consistent interface brings all workflows together in a single logic.
Ergonomics in the OR
The narrow, free-standing base on castors can be positioned flexibly at the patient. A clean port and cable concept supports hygiene, safety and a calm working environment.
One Design Language Across Three Configuration Levels
The platform grows with clinical demands without losing its design identity. From the anterior segment to the fully equipped variant with integrated laser, all configurations share the same design language, the same operating concept and the same accessories. For users this means recognisability and short familiarisation; for the manufacturer, a consistent product family with a clear brand presence.

“Good medical design makes complexity manageable. It translates technical performance into a form that is immediately intelligible in the operating room.”

What This Means for Your Product
The higher the functional density of a medical device, the more medical design contributes to its acceptance. We translate complex technology into products that are intuitive to operate and ergonomically convincing. From the first concept study to series production readiness, we develop a form that makes your company's ambition visible and holds up in clinical practice.

Proven Usability
The entire user interface was designed by Eckstein Design, from the home screen through parameter settings to the service dialogues. Six surgical functions, previously distributed across two or three devices, had to come together in a single operating logic without increasing cognitive load in the operating room.
To achieve this, the interface follows one consistent principle: navigation and context on the left, the detail area on the right, and a persistent bar at the bottom showing surgeon, procedure and current surgical step. On the surgery screen, each function has its own module in a fixed colour, with the current value large and luminous and the target value small above it. Numbers on the modules refer to the corresponding illuminated port on the device: software and hardware speak the same language. The dark interface is designed for the darkened room, with blue reserved for active values.
Usability here was not claimed but tested. In a summative validation to IEC 62366-1 at RWTH Aachen University, 13 first-time users rated the system with a satisfaction score of 91.7 percent, with no unacceptable residual risks. All participants rated the illuminated ports positively, a detail that makes the difference in a darkened operating room.
