Explore the FEMTON F1 by touching the Hotspots.
TOUCHSCREEN MONITOR and GLASS KEYBOARD for easy user interaction.
The specially designed ROBOTIC DELIVERY ARM is of compact design to fit under most operating microscopes and Excimer Lasers.
FLEXIBLE HEIGHT ADJUSTMENT RANGE for easy adaptation on existing patient beds. Designed to be combined to an already existing Excimer Laser and especially to the Micron M7 Excimer Laser.
Centration during docking is done automatically by using eyetracking technology. This can be toggled with the optional joystick.

The FEMTON F1 Philosophy

Our initial idea is to design a laser which is versatile, offering many treatment options.

Mobile for use in different operating rooms within the clinic. Upgradable and compatible to already existing Excimer Laser Systems or surgery tables.

Treatment Options

The FEMTON F1 Laser is open to a large number of applications. The basic configuration includes LASIK Flap, Refractive Lenticule Extraction, Intrastromal Pockets, Intrastromal Tunnels and optionally it can be extended for cataract surgery. More applications will be added.


All major functions can be controlled by the large touchscreen. The software is designed in an intuitive and straightforward way, leading the surgeon through the procedure. The automated centering feature with a single piece patient interface makes docking simple and safe.


The FEMTON F1 is stable, compact and mobile. It can be repositioned on the hospital floor, when not needed.


When designing the FEMTON F1 we ensured compatibility to most existing Excimer Laser systems. The laser can easily be moved and positioned near by to the patient bed.

Treatment Methods with the FEMTON F1

Refractive Lenticule Extraction
Intrastromal Pockets
Intrastromal Tunnels
Cataract (Optional)

The HexaScanTM Principle

The EXCELSIUS FEMTON F1 is using a unique scanning pattern creating high efficiency tissue cut with flexibilities on the size and type of applications.

The treatment area is divided into smaller hexagonal segments. The proprietary Femton F1 operating software is using a self learning algorithm determining the size and number of hexagons used for an optimum balance of speed and resolution for each treatment.


Hexagon sizes adjusted automatically for best speed and cut quality.

1. Flap rim, down cut can be customized
2. Hexagon sizes are optimized according to flap diameter

Refractive Lenticule Extraction

Hexagon sizes adjusted to ensure tissue saving technology can be realized to maximize the optical zone of lens.

Intrastromal Pockets

For Intrastromal Pockets the hexagon spacing is optimized for speed and optimum cut quality to minimize optical distortions when inserting a lenticule implant.

Intrastromal Tunnels

For Intrastromal Tunnels to ensure easy opening, tunnel width and depth as well as access cuts can be customized.

Patient Comfort and Unique Interface Design

The FEMTON F1 is designed for the best patient comfort. Similar to the MICRON M7 Excimer Laser, the delivery arm is moved aside for surgery preparation.The surgeon has full access and free microscope view to the patient eye for draping, applying topical anesthetics and general procedures.

Then the delivery arm is positioned over the eye to be treated. After docking the cut is performed.

During the cutting process the surgeon can observe the whole procedure via the integrated video system. After cutting the applicator arm is moved aside, and the treatment can be continued either by Excimer Laser for LASIK or using the operating microscope for other treatment types.

The FEMTON F1 uses a single piece patient interface. Optical interface and suction ring are made in one part. This makes the surgery setup quick and easy. Once centered and touching the eye, suction is applied to complete the docking procedure and fixate the eye.


Easy Positioning.
Move Laser towards patient bed, position and lock.


Move robotic arm to the eye to be operated.


Perform surgery.


Move robotic arm out of the way.


Easy Release.
Move laser away again when not needed anymore.


When designing the FEMTON F1 system intensive attention was paid to easy serviceability and a straightforward modular structure.

This results in great stability and a small number of necessary spare parts. Only application interfaces which are intended for bilateral use are needed as acccessoires.


The FEMTON F1 is a modularized design as one compact unit. The laser system weighs only 200 kg which make it easy to handle and transport.

Moving the laser away when not needed is easy. Also it can be moved towards a patient bed of an Excimer Laser or ophthalmic surgery table for various procedures.

The width of only 790mm allows passage through the most standard doors.
