The DGH Scanmate A also called the DGH 6000 A-Scan is a modern eye ultrasound device used by eye doctors to measure the size and parts of the eye. It is small, portable, and connects to a computer by USB. Doctors use it mainly to measure the axial length of the eye — an important step in cataract surgery and myopia short-sightedness control.
The Scanmate A is made by DGH Technology, a well-known company in eye diagnostic equipment.
This machine helps doctors get quick, correct, and repeatable results for many types of eye measurements FREHF.
What the DGH Scanmate A Does
The Scanmate A is an A-Scan ultrasound biometer. It sends sound waves into the eye and measures how long they take to bounce back. This helps the doctor know how long the eye is and how thick each part is.
Main uses
-
To calculate the power of artificial lenses before cataract surgery.
-
To measure eye growth for myopia management.
-
To record and track eye health changes over time.
Important Features
Dual Measurement Modes
The device can take measurements in two ways:
-
Contact Mode – The probe lightly touches the cornea. The device has a pressure lock system to avoid pushing too hard.
-
Immersion Mode – The probe measures through a liquid saline using a shell called a Prager shell. This method is more accurate and does not touch the eye directly.
Smart Alignment System
-
Shows an alignment score to help the user hold the probe correctly.
-
Filters out wrong or unclear readings automatically.
-
Makes the results more consistent between different operators.
Easy Computer Software
The device runs with Scanmate software on any Windows computer. It helps manage patient data, analyze measurements, and print reports.
Main software features:
-
Searchable patient database
-
IOL calculation using modern formulas
-
Axial length tracking for myopia
-
EMR and PDF export for easy sharing
Portable and Simple
-
Small and lightweight
-
Powered by USB — no power cord needed
-
Ideal for clinics, mobile eye units, or small hospitals

Typical Clinical Uses
Cataract Surgery
Doctors measure the eye’s axial length to find the perfect IOL power before surgery.
Post LASIK and PRK Eyes
The device supports formulas made for patients who had laser vision correction before cataract surgery.
Myopia Management
Tracks eye growth in children and young adults.
Shows small axial-length changes on a graph to monitor treatment success.
Mobile Eye Units
Because it runs on USB power, it’s ideal for vision camps and outreach programs.
