dgh a in Eye Care: The Scanmate A‑Scan
What does it do?
The DGH 6000 Scanmate A‑Scan is a portable ultrasound device used by ophthalmologists. It helps measure things like:
- The length of the eyeball (axial length)
- The depth of the front part of the eye (anterior chamber)
- The thickness of the eye’s lens
These measurements are essential for calculating the correct power of intraocular lenses (IOLs) that are implanted during cataract surgery.
Key Features
- Portable and USB-powered: Easy to carry and use with any laptop or desktop.
- Real-time feedback: Gives you audio and visual signals to guide you during the scan.
- High precision: Accurate to 0.01 mm, which matters when you’re preparing for eye surgery.
- Supports multiple IOL formulas: Including SRK/T, Hoffer Q, Haigis, and more.
- Software integration: Stores patient data and generates detailed reports.
Why It Matters
Getting the correct measurements before eye surgery can mean the difference between perfect vision and blurry results. That’s why tools like the Scanmate A‑Scan are so valuable. They help ensure that doctors get it right the first time.
