INTRODUCTION
Thank you for purchasing the TOPCON OMS-800 Operation Microscope.
This product is an operation microscope for operations, treatment or observation.
This product is classified in five types according to the difference in the combination of the
microscope unit with the base unit. Each of five types is classified into two different types: one
type is equipped with a beam splitter of the fixed spectral ratio and the other with a
changeable beam splitter which can alternate two spectral ratios to each other.
•OFFISS : The microscope unit with the front lens is combined with the inverter and the
base unit with the electromagnetic lock and the rough focusing unit.
•OFFISS Lite : The microscope unit with the front lens is combined with the inverter and the
base unit with the electromagnetic lock and without the rough focusing unit.
•Pro : The microscope unit without the front lens is combined with the base unit
with the electromagnetic lock and the rough focusing unit.
•Pro Lite : The microscope unit without the front lens is combined with the base unit
with the electromagnetic lock and without the rough focusing unit.
•Standard : The microscope unit without the front lens is combined with the base unit
without the electromagnetic lock and the rough focusing unit.
This product has the following features.
•OFFISS* is mounted to greatly enhance the glass body operation. (Only in OFFISS, OFFISS Lite.)
•Compact base and long arm provide a comfortable and extensive operation area.
•Electromagnetic lock is used to set it correctly at the required position. (Only in OFFISS,
OFFISS Lite, Pro and Pro Lite.)
•The 45°~90° variable eyepiece lens is used to set the optimum operation position.
This Instruction Manual describes the TOPCON OMS-800 Operation Microscope, and
includes outline, operations, troubleshooting, maintenance and cleaning.
To get the best use from the instrument, read "DISPLAY FOR SAFE USE" and "SAFETY
CAUTIONS". Keep this manual at hand for future reference.
*OFFISS is an abbreviation of Optical Fiber Free Intravitreal Surgery System.
[Warning]
Before using this instrument, make sure that the components are set and fixed securely.
[Falling components may cause injury or death.]
Before using this instrument, adjust the balance of the 2nd arm.
[The microscope may move up and down suddenly, leading to injury.]
When using the coaxial illumination in the ophthalmic operation, use the minimum
illumination sufficient for operation.
[Exposing the patient’s retina to excessive light may lead to retinal trouble.]
To reduce or prevent retinal trouble, use the front lens within 40 minutes (illumination
light intensity display: 0.7)/within 70 minutes (illumination light intensity display: 0.4).
[Using the front lens for a long time may lead to retinal trouble.]
When using the front lens, make sure it does not come into contact with the patient.
[Injury may result from a unit coming into contact with a patient.]
