NIDEK Optical Biometer AL-Scan

Technology

10 Seconds to Measure 6 Values

NIDEK’s solution is the state of art optical biometer – the AL-Scan. In 10 seconds, six values for cataract surgery are measured:

  • Axial Length
  • Corneal Curvature Radius
  • Anterior Chamber Depth
  • Central Corneal Thickness
  • White-to-White Distance
  • Pupil Size

Rapid measurements are essential for clinical efficiency and patient comfort.

3D Auto Tracking And Auto Shot

Automated Functions for Accurate Alignment

The AL-Scan incorporates NIDEK’s much acclaimed 3D auto tracking and auto shot, which provides the operator with the most ease, comfort, and accuracy on all measurements.

The 3D auto tracking tracks eye movements on the X-Y-Z planes to ensure accurate alignment of the eye. Once correct alignment is completed, the auto shot immediately captures the image and data.

3 Imaging Functions for Observing Anterior Segments

Easily diagnose with AL-Scan’s imaging of lens, pupil, and double mire rings. Observe anterior segments with sectional lens image, pupil image, and reflected image of double mire rings projected onto the cornea.

Optional

Measure More with a Built-In Ultrasound Biometer

Measure virtually any cataractous eye without having to move the patient in cases where the optical biometer cannot measure an eye with a cataract.

What’s even better? The AL-Scan requires no connection with an external ultrasound unit.
