DGHA, often called the Scanmate A, comes from DGH Technology. It serves as an A-Scan ultrasound gadget for eye pros. Compact and easy to carry, it connects to computers via USB. Doctors use it to gauge eye parts like axial length, anterior chamber depth, and lens thickness. Such measurements aid in planning surgeries or tracking conditions. The device blends tech with user-friendly design, making it popular in clinics worldwide. Its accuracy helps avoid errors in treatments.
What is DGHA?
This section gives a basic overview of DGHA, explaining its core purpose and design.
DGHA refers to the DGH 6000 Scanmate A, a specialized ultrasound instrument in ophthalmology. Made by DGH Technology, Inc it focuses on A-Scan biometry. The tool looks like a small box with a probe, weighing under a pound. It needs a Windows computer to run its software. Eye specialists pick it for quick, reliable scans. Unlike bulky machines, DGHA fits in bags for mobile use. Its main job involves sending sound waves into eyes to capture data.
The company behind DGHA started in 1982. DGH Technology grew from a focus on ultrasound pachymeters to full A-Scan and B-Scan lines. Based in Exton, Pennsylvania, it aims at affordable, quality gear for eye care. Over years, innovations like portable designs set it apart. DGHA represents that progress, offering features once limited to big setups. Pros appreciate its balance of cost and performance in routine tasks.

History of DGH Technology Inc.
Here, a short look at the company’s background shows how DGHA came about.
DGH Technology Inc. began operations in 1982. Founder Earl Henderson saw needs in eye ultrasound tech. Early products centered on pachymeters to measure corneal thickness. Success led to expansion into A-Scans by the 1990s. The firm earned a name for durable, user-focused items. Milestones include portable models that changed clinic workflows. Today, it remains independent, serving global markets with consistent quality.
Growth came through listening to doctors’ feedback. In the 2000s, DGH added software improvements for better data handling. The Scanmate series, including DGHA, launched around 2010. It addressed calls for lighter, versatile tools. Federal approvals, like FDA clearances, boosted trust. The company’s story highlights steady innovation without rushing trends.
How Does DGHA Work?
This part breaks down the device’s operation in simple steps.
DGHA uses ultrasound principles for eye measurements. The probe emits high-frequency sound waves at 10 MHz. These waves travel through eye tissues and bounce back as echoes. The device times how long echoes take to return. Software then calculates distances based on sound speed in eye parts. For example, axial length gets figured from cornea to retina. Modes include contact, where the probe touches the cornea, or immersion, using a water shell to avoid pressure.
In practice, a tech attaches DGHA to a computer. Patient data goes in first. The probe aligns with the eye, guided by sounds and screen feedback. Good alignment earns stars – three means best. If pressure squishes the cornea, a lockout stops bad readings. After scans, IOL formulas compute lens powers for surgery. Reports print or save easily.

A-Scan biometry relies on precise echo detection. DGHA’s algorithm spots patterns for accuracy. It handles different eye types, like those with cataracts or implants. Immersion mode suits sensitive cases, reducing compression risks. Contact mode works faster for routine checks. The process takes seconds per eye, minimizing patient discomfort. Results store in databases for later review.
Key Features of DGHA
A quick note on standout elements that make DGHA useful.
One main feature involves real-time feedback. During scans, tones signal alignment quality. Stars rank each attempt, pushing for better ones. Compression lockout guards against squished corneas, adjustable for needs. The software packs IOL formulas like SRK/T or Haigis. Post-refractive options help after LASIK. Custom velocities allow tweaks for unique eyes.
Portability shines with USB power and light weight. It fits small spaces, ideal for travel clinics. Myopia reports track axial growth over time. Video saves let doctors replay scans. EMR exports keep records smooth. The probe, fixed at 10 MHz, ensures consistent output. Ranges cover 15-40 mm axial lengths, fitting most patients.
DGHA includes accessories like the Prager Shell for immersion. Software runs on standard Windows setups. Backups protect data. Reports customize with logos or notes. These traits combine for efficient, reliable work.
