DATEYE

MYAH Optical Biometer

The Topcon MYAH is a slit-lamp-based optical biometer that measures axial length, keratometry, and pupil diameter. DATEYE imports biometry measurements from MYAH XML export files and stores them in the local database. Import direction: MYAH → DATEYE (file-based, XML).

Overview

MYAH exports measurements as UTF-16 encoded XML files. DATEYE monitors a folder on your computer or network for new XML files and imports them automatically. No network connection to the MYAH device is required — the data transfer happens through the shared file system.

Each XML file corresponds to one measurement session (one patient, one exam). DATEYE parses the file and stores axial length, keratometry values (K1, K2), and pupil diameter for both eyes.

Prerequisites

Before configuring MYAH in DATEYE, complete the following steps:

  • Configure MYAH to export XML files to a network-accessible folder. Refer to the MYAH operator manual for export settings.
  • Ensure the folder is accessible from the computer running DATEYE. For a network share, mount or map the share before starting DATEYE.
  • Verify that DATEYE has read permissions for the export folder.

Step-by-Step Walkthrough

  1. Open DATEYE and navigate to the Connections screen.
  2. Click the + button to add a new connection.
  3. Select MYAH from the device list.
  4. Enter the full path to the watch folder in the Watch Folder field. Use the folder browser button to navigate to the correct location.
  5. Enable Auto-Import to have DATEYE import files as soon as they appear in the folder.
  6. Click Save to create the connection.
  7. Place a test XML export file from the MYAH into the watch folder.

The connection card on the Connections screen will turn green once DATEYE confirms it can read the folder.

Verification

Expected result: The MYAH connection card shows a green status indicator. Within a few seconds of a new XML file being placed in the watch folder, a new entry appears in the History screen.

If the connection card shows an error:

  • Check that the watch folder path is correct and the folder exists.
  • Verify that DATEYE has read access to the folder (check folder permissions on your operating system).
  • On Windows, ensure network shares are mapped with a drive letter if entering a UNC path does not work.

If no measurements appear after placing a test file:

  • Confirm that Auto-Import is enabled on the connection card.
  • Check that the file is a valid MYAH XML export (UTF-16 encoding, .xml extension).
  • Review the History screen filter — new imports appear at the top when sorted by date.
