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 cla ssified int o two dif ferent 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 rou gh 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 focusi ng 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 enhan ce the glass body operation. (Only i n 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.

[Warning]

Before using this instrument, make sure tha t th e components are set and fixed securely .

[Falling components may cause injury or death.]

Before using this instrum ent, 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.]

*OFFISS is an abbreviation of Optical Fiber Free Intr avitreal Surgery System.

maximum value.

2 Turn the diopter adjustment ring counterclockwise to its maximum value and gently move the

microscope unit up and down with the focus up/down switch until the object i s in focus.

3 Operate the zoom up/down switch of the foot switch to set the observation magnification at

minimum value.

4 While looking through the eyepiece lens for each eye, turn its diopter adjustment ring clockwise

until the object is in focus and can be clearly seen. The dioptric power is now properly adjusted. The scale of the diopter adjustment ring displays the correct dioptric power.

Record the correct dioptric power for each eye. Then adjust the dioptric power to the value.

It is possible to operate the variable illumination aperture and to perform the front lens focusing operation.

Operating the front lens

1 Hold the microscope operation handle and press the electrom agnetic lock release switch. Then

adjust the microscope position to condense the illumination light on the surface of cornea.

The distance between the cornea and the bottom of the front lens is approx. 20mm.

2 Let the illumination light enter through the cente r of cornea by using t he X-Y translat or lever swi tch. 3 If you see a flare (reflected light) in the observation visual field through the microsc ope, move the

front lens up and down with the front lens focusing switch until the flare disappears. The flare may not disappear because of the difference between eyes or because of the IOL transplantation eye.

Operating the variable illumination aperture provides an observation image with better contrast and less flare. (Refer to "OPERATION OF THE VARIABLE ILLUMINATION APERTURE: OFFISS, OFFISS Lite" on P. 76.)

OPERATIONS IN USE

4 Bring the observation section into focus by operating the focus up/down switch.

Adjusting the stereo variator to IN provides an acute stereo angle for bino cular observation. This reduces the shading caused by the cornea, even for microcoria patients. (Refer to "OPERATION OF THE STEREO VARIATOR: OFFISS, OFFISS Lite" on P. 75.)

Storing the front lens

Binocular observation of observing the eye ground through the front lens may be difficult, as the patient’s cornea is small. In such a case, use the variator.

1 Move the stereo variator lever to the right to set the stereo variator to IN.

Adjusting the stereo variator to IN provi des an acute stereo angl e for binocular observ ation. This reduces the shading caused by the cornea, even for microcoria patients.

While the stereo variator is under the IN condition, the -2° illumination cannot be used. When the front lens is not used, set the stereo variator to OUT.

HOW TO USE THE ANTERIOR EYE SECTION OBSERVATION LENS: OFFISS, OFFISS Lite

While the anterior eye section observation lens is in use, do not operate the front lens IN/OUT lever and the front lens connecting/disconnecting

1 Set the D cut surface of the anterior eye section observation lens at the back and the engraved

surface at the front. Then fit the anterior eye section observation lens onto the front lens.

Putting the anterior eye section observation lens on the front lens changes the observation focus position of the microscope from the eye ground to the anterior eye section.

HOW TO USE THE PERIPHERAL OBSERVATION PRISM: OFFISS, OFFISS Lite

Use this prism to observe the periphery of the eye ground while the front lens is in use. Sterilize the peripheral observation prism before operation.

While the peripheral observation prism is in use, do not operate the front

W ARNING

lens IN/OUT lever and the front lens connecting/disconnecting knob. The peripheral observation prism may fall off, causing an injury.

1 Fit the peripheral observation prism onto the front lens.

This greatly alters the condensing point of the il lumination light just under the front lens.

OPERATIONS IN USE

2 Turn the peripheral observation prism so that its slope surface direction is opposite to the

direction of the periphery to be observed.

Turning the peripheral observation prism greatly alters the condensing point of the illumination light emitted from the front lens.

3 Move the microscope horizontally with the X-Y translator so that the condensing point of the

illumination light emitted from the front lens is aimed at the pupil of the patient's eye.

For safety’s sake, carry out the above adjustment watching the patient’s eye directly, without using the microscope.

4 While watching the patient's eye through the microscope, remove flare (fine movement of the

front lens) and perform focusing (focus up/down swit ch operation).

5 When you change the position of the periphery to be observed, also perform the above 2 ~ 4.
