Patient bed for refractive eye laser surgery
(exclusive for our industry customors)
LS Comfort
AKRUS, since many years, is the leading supplier for patient beds in the market for refractive laser eye surgery. The LSC patient bed offers high quality technology and, with its superior features and functions, has established a “state of the art” reputation with many laser manufacturers and operators.
Thanks to the high precision adjustments and movements on the Z, X and Y axis ther patient bed can be positioned exactly to the “focal point” of any laser.
The head rest features an electric movement of 50 mm up-down and a manual tilt of -20° and + 15°.
With the integrated safety systems and interlocks the use of the bed is possible in combination with both, an excimer laser and even under a femtosecond laser with a non-moveable laser head.
As an option, the bed top rotates by 35° to the left and/or right, so the two laser types could be combined to one homogeneous suite.
The analog joystick guarantees a high precision speed control. The speed control ranges from as slow as 0,2 mm/sec up to 12 mm/sec.
Some of the leading laser manufacturers use the LSC in combination with their excimer or femto second lasers
Features and Functions
Electric adjustments
The electric Z, X and Y movements come as a standard with the LSC bed. The movements are controlled by an analog joystick. The joystick is either integrated in the head rest or in a separate joystick box on the left or right side of the bed.
The electric head rest moves up-down by 50 mm.
Head rest adjustments, electric and mechanical
Electric movements
The head rest moves up to 50 mm up- down, controlled by buttons integrated in the head rest body.
Mechanical movements
The head rest offers a mechanical tilt of -20° and +15°. This is a very important safety feature for procedures under a femto second lasers with a fixed laser head. In case of a power failure during a procedure and no auxiliary power supply the patient can be released from under the laser by the – 15° tilt.
Interlocks
To safely operate the LSC, various interlocks are available. During certain “mode” settings of the laser the interlocks will safely disconnect the bed from power supply by a relay. The functionalities of the interlocks incl the firm ware are being customized with each customer according to their specs and safety concept.
Accessoires
Bed top rotation
With the optional rotation of the bed top, various lasers can be combined to one homogeneous laser Suite. The maximum rotation angle referenced to the center line is 35°.
- 35° left OR right
- 35° left AND right (ttl 70°) for a suite of a femto and excimerer laser.
Moreover, additional stop positions in between are available for instance for cataract surgery in combination with a laser.

Set of wheels
To transport the bed to its working position or temporarily move it away, a detachable set of wheels is available.
The wheels are not cleared for the transport of humans.
