NOTES

Installation with external devices

The CA-200F corneal analyser complies with the CE marking requirements.

Before connecting an external device (computer, printer, display, keyboard, mouse, slit lamp), check that

these devices are in compliance with the EN 60950-1 standards and bear the CE marking.

If the CA-200F corneal analyser is installed in rooms for medical use, any connected personal computer and

printer must be powered by an insulated transformer in accordance with IEC 60601-1.

If the CA-200F corneal analyser is installed in rooms for medical use and is not connected to a computer,

there is no need to use an insulated transformer. If a printer is connected directly to the CA-200F corneal

analyser, it must be powered by an insulated transformer in accordance with IEC 60601-1.

INTENDED USE

Use:

CA-200F is a corneal analyser with integrated pupillograph.

The instrument acquires images of the cornea and analyses its topography.

The software selects the image with the best focus out of a sequence of images.

In the image, the rings of the disc reflected by the illuminated cone are used to geometrically calculate the

topographic map of the cornea. From the topographic map data, a set of parameter indices are processed

for the measurements.

The main applications of the corneal analyser are the following:

Cornea measurements for diagnostic instruments

Cornea and pupil measurements for application of contact lenses

Fluorescence analysis for contact lens positioning

Pupil measurements for the determination of specific pathologies

Users:

Eye specialists, ophthalmologists, opticians, optometrists.

The instrument must be used by qualified persons.

Facilities:

Health centers, optician shops, eye hospitals and other eye-care related facilities.

This product is in compliance with the EMC standards (IEC 60601-1-2:2001).

- ELECTROMEDICAL DEVICES require particular precautions for electromagnetic compatibility and

must be installed and set up based on the EMC information provided in the accompanying

documents.

- Portable RF communication instruments may interfere with medical devices.

- Using accessories and cables different from those provided with the instrument, except for the

cables sold by the equipment manufacturer as spare parts, may result in increased emissions and

reduce the immunity of the device or system.

- The device must not be used in contact with other equipment.

If it is inevitable to use the device in contact with other instruments, check proper functioning in the

required configuration.

1. BASIC OPERATIONS

GENERAL DESCRIPTION

CA-200F is a corneal analyser with the following functions:

 Cornea image acquisition and topographic analysis;

 Dynamic pupillometry acquisition: recording of a sequence of images of the pupil as the light

conditions change. Static pupillometry acquisition in controlled light conditions (photopic, mesopic

and scotopic);

 Fluorescein analysis: picture and/or movie acquisition to view contact lens positioning and cornea

acquisition to assess its artefacts and the lachrymal film (rupture time);

 Analysis of wavefront corneal aberrations generated by the front surface of the cornea with Zernike

analysis: information on the optical properties of the cornea and the optical problems that may

disturb sight;

 Contact lens simulation: the software selects from a database the lens best suited to the eye and

allows comparing different lenses;

 Intraocular lens calculation (Toric IOL).

SOFTWARE RELEASE: from 1.0.1

ACQUISITION

When the device is turned on, the software is automatically loaded.

CA-200F can operate in two different ways: exchanging data with a PC or stand-alone.

Described below are the acquisition procedures for operation connected to a remote PC as well as in stand-

alone mode.

ACQUISITION WHEN CONNECTED TO A PC

To use the instrument connected to a remote PC (Wi-Fi or LAN), the PC Link software module must be

activated (see the “Module Update” section in “Administrator Tools”).

When the instrument is turned on, the Patient Details window is displayed (fig. 1-1).

fig. 1-1

You can insert a new patient or select an existing patient from the database of the PC connected to the

analyser.

To insert a new patient, fill in the patient details fields using the on-screen keyboard. If you need to insert

special characters, keep pressing the letter buttons: a panel with the choice of the possible characters for the

selected letter will appear (example fig. 1-2).

Press the “Open” button to access the acquisition window for the patient just inserted.

fig. 1-2

There are two ways to select an existing patient from the database of the PC:

 Type in the patient’s name or surname or part of them and press the “DB List” button to open a

dialogue window with the PC (fig. 1-3).

fig. 1-3

CA-200F Corneal Analyser - Rev. 7 16/01/2012

20

If the communication between the PC and the device is correctly established, the patients that match

the criteria entered will be displayed in the dedicated section (fig. 1-4) . Select the patient and press

the “Open” button or double-tap on the patient’s name to access the acquisition window.

If the communication between the PC and the device is not correctly established, see the

“Troubleshooting” section.

fig. 1-4

 Press the “DB List” button to open the dialogue window with the PC: the patients list will appear in

the dedicated section (fig. 1-5). Use the “UP” and “DOWN” buttons to scroll the list and select the

patient as described above.
