Topcon KR-8100PA Auto Kerato-Refractometer

Specifications

Topcon, leader in the ophthalmic field, now offers the most advanced technology thatprovides significant operational conveniences and totally reliable diagnostic results in Auto Refractometry and Auto Kerato-Refractometry. Topcon’s KR-8100PA also features a highly sophisticated Corneal Mapping System.
The time required for the calculation and printout of mapping has been cut down by 70% due to the latest CPU and sophisticated algorithms applied to the KR-8100P. Also the total time for 5 measurements ( Kerato-Refractometry) of both eyes and printout including mapping has been cut down by more than 50%.
The innovative design of the KR 8100PA enables accurate, reliable refraction and keratometric measurements within a pupil dilation as narrow as 2.0mm. This means it is easier to obtain more precise diagnostic results when dealing with glaucoma, asymmetric pupils or elderly patiens.
The newly introduced KR-8100PA features superior handling and multi-functionality in a compact design. It offers you the most reliable and accurate kerato values by making use of the placido ring and the sophisticated measurement principle.
Auto-Alignment
(KR-8100PA only) The 3D auto-alignment system offers easy operation and speedy measurement making it possible to automatically obtain precise focus without any skill.

Auto-Start
The KR-8100PA offers an Auto- Start function. As soon as the instrument is properly aligned, this innovative function initiates the measurement process and completes three readings of each eye. When the readings are complete, a printout of measurement results is automatically generated.
TOPCON’S KR-8100PA provides you with the functions of an auto-refractometer, auto-keratometer and even a mapping function in a single compact designed instrument.
Mapping /Overlay
The KR-8100PA provides accurate refraction and keratometry measurements. It also displays corneal mapping very quickly and even overlays the mapping output onto the anterior segment by a single touch.

Corneal Irregularity Detection
In case of corneal irregularity, the placido ring projected on the cornea will be sort of distorted. However, if the irregularity is not substantial, it will not be noticeable. KR-8100PA 8100P detects corneal irregularity like irregular astigmatism and gives a marking to attract the operators attention.

Wider Measuring Area
Now with the KR-8100PA, wider area of 1.5mm -9.2mm can be measured using 10 placido rings (in case of R-8mm).

Base Curvature Advice
Based on the mapping data the KR-8100PA 8100P advises the base curvature (BC) for the contact lens The KR-8100PA 8100P reconstruct corneal shape from mapping data of the whole cornea obtained by the projected placido rings. The internal software calculates the radius of curvature of a circle consisting of 3 points (2 optic zone ends and corneal peak on the same meridian) This is done for totally 4 meridians to assure the best BC.
This method has proven to be effective even in case of keratoconus.

Scenic Fixation Char
This scenic color chart is adjustable in two brightness levels for optimal results with large or small pupils, making eye fixation easier. The auto- fogging function reduces the effects of instrument myopia and patient accommodation.

Omni-Directional Joystick
Fast, positive and responsive control of operation is performed with TOPCON's omni-directional joystick that leaves the user one hand free to operate other functions. Even novice operators can obtain excellent results. The vertical movement is motorised. In combination with the auto-alignment it makes the handling of the instrument very easy.

Improved Functionality
Auto Shut-Down
To conserve energy and prevent any built-up of heat from electronic circuitry, the instruments incorporate an automatic function that shuts down the instrument when left unused for more than 10 minutes.

Automatic PD Measurement
For binocular readings, PD measurements are performed automatically; the value obtained are stored in the patient's data file and printed out together with the results of objective tests.

Corneal Diameter Measurement
Corneal diameter can be measured either during testing of the patient or later by recalling an image of the comea on the monitor Measurements can be obtained for both eyes, with the data recorded on the printouts if required.

Printing Measurement Results
A complete printout of test results for record purposes can be obtained by one the print switch. The operator choose out of 3 data formats.

ALL
Prints out all measurements (10 readings per eye) with date.

AVE
Prints out averaged value for all measurements with date.

SIM
Prints out only the average measurement value of a readings.

By changing the output format, mapping images can be include/excluded. It is even possible to printout mapping separately.
