OM-9 Operating Microscope

A Compact High-performance Operating Microscope with LED Illumination

OM-9 is a  Compact High-performance Operating Microscope delivering high efficiency and versatile functionality, complete with high illumination LED light source.

OM-9 is the perfect choice giving complete product satisfaction to the operator, and offering the highest level of patient safety.


OM-9 can be fitted with Oculus BIOM for vitreous surgery.



Renewed Design

  • Most cables are concealed minimizing dust attachments and reducing interference between operator and instrument.
  • Cables for connecting an imaging system can also be concealed, achieving a sleek stylish hygienic design.
  • New product color scheme adds to the overall high quality feeling.

* The image on the monitor is created by inlay. An actual displayed image may look different from it.


Use of High-luminance LED light source

  • New red reflex illumination combined with a high luminance LED gives OM-9 a brighter reflected light from the fundus.
  • Bright and sharp LED having excellent color reproducibility is used for OM-9.

Reduction of the Characteristic Blue Light of LED

  • The projected light is soft and easy on patient’s eyes by using a new blue correction filter, reducing the peak of the characteristic blue wavelength of LED.

Optical Design

New Optical System

  • New OM-9 optics are suitable for both cataract and vitreoretinal surgery.
  • By adopting a standard objective lens F=200 mm, the OM-9 is fully suited for vitreoretinal surgery. (compatible with a BIOM viewing system)
  • 10x eyepieces bring a wider, brighter & sharper view with a larger depth of focus.*

*Compared to OM-8


Tiltable Binocular Tubes

  • Tiltable binocular tubes available, which can incline more than 90° depending on the posture and physique of the operating surgeon.
  • Movable range: 0° (straight) to 90° (inclined)

Microscope Tilting Mechanism

  • By adopting the knob interlock system, the microscope tilts back and forth easily, necessary in the application of glaucoma surgery.
    Movable range: around ±30°
