How It Works
Setup
Install the Scanmate software on a Windows computer
Plug the probe into a USB port
Add patient name and eye data
Choose the type of test
The device does not need a power plug.
It starts as soon as it connects by USB.
Taking a Measurement
Choose the right eye or left eye
Pick contact or immersion mode
Align the probe with help from stars on the screen and a beep sound
Take five or more good readings
The system removes bad readings and gives an average
Print or save the report
Contact Mode
In this mode the tip touches the cornea with gel.
It is quick and easy but the user must not press hard.
Immersion Mode
The probe floats in a shell filled with water or saline.
There is no touch on the cornea so results are more correct.
It is good for long eyes and dense cataracts.
Compression Lock Out
The program blocks any reading that looks too short.
This stops errors that come from pressing the probe too much.
Software and Reports
The Scanmate program changes ultrasound echoes into clear numbers.
It gives full reports that are easy to read.
IOL Calculation
The machine uses many eye formulas.
These formulas help find the right lens power for cataract surgery.
It uses axial length anterior chamber depth and corneal curve data.
Axial Length Progression
For people with myopia it tracks the eye length over time.
The chart shows how much the eye grows each year.
This helps doctors see if treatment is working.
Saving and Sharing
Results can be saved as PDF files or sent to a clinic network.
They can also go into the hospital record system.
Custom Reports
Clinics can add their own logo and text to reports.
This makes the files look professional for patients and hospitals.
How Doctors Use It
Cataract Surgery Planning
Doctors use DGH A to measure the eye length before surgery.
A small change in length can change vision after surgery.
High accuracy means better lens choice and better results.
Myopia Control
The tool helps track myopia in children and teens.
Even a 0.1 mm increase shows that the eye is getting longer.
The report shows the growth line so the doctor can react fast.
Special Cases
It can measure eyes that had laser surgery before.
It also works with dense cataracts or eyes with silicone oil.
Mobile Eye Camps
It is light and easy to carry.
Doctors can use it in small clinics or field work.
Why It Is Useful
Good Points
Easy to carry and connect
Works only with a computer and USB
High accuracy and repeat results
Easy screen and sound guide
Many IOL formulas
Makes PDF and digital reports
Lower cost than big machines
Fits in modern clinic workflow
Points To Remember
Needs gel or fluid to work
Contact mode needs a steady hand
Does not read corneal curve itself
Works with a Windows computer only
Cleaning and Care
To keep it working well follow a simple care plan.
After Each Use
Wipe the probe with approved cleaner
Check that the tip is clean and smooth
Keep the probe dry and safe
Each Month
Test the probe on a model eye
Make sure the readings stay correct
Update the software when the maker releases new versions
Each Year
Send it for a full check if needed
Replace the probe if it shows wear
Good care keeps the results true and extends the life of the tool.
Cost and Value
The DGH A costs about 4000 US dollars in many markets.
It is also sold in the UK for around 4000 pounds before tax.
Why It Saves Money
No heavy console needed
Uses the same computer as other work
No special power parts
Few repairs and low upkeep
Long life span
Even small clinics can earn back the cost fast.
It gives precise data that helps prevent repeat surgery.
Rules and Safety
The DGH A has passed strict safety checks.
It is cleared by the FDA in the United States
It has CE approval for Europe
It meets global medical safety standards
It has a normal two year warranty
It also uses safe probe materials that can be cleaned with hospital cleaners.
Future Updates
New versions of eye ultrasound are in progress.
Companies are adding smart tools like:
AI that reads traces automatically
Combined A and B scan probes
Cloud data backup
Links with optical biometers
These steps will make eye scans faster and even more exact.
Still the DGH A is already a very good balance between power and price.
