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.
