10 seconds to measure 6 values
NIDEK’s solution is the state of the 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.
3-D auto tracking and auto shot
With the introduction of the AL-Scan, NIDEK continues its tradition of providing user friendly equipment. The AL-Scan is so intuitive that personnel require little to no training for obtaining measurements.
The AL-Scan incorporates NIDEK’s much acclaimed 3-D auto tracking and auto shot, which provides the operator with the most ease, comfort, and accuracy on all measurements. The 3-D 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.
Enhanced Possibility to Measure Cataractous Eyes
Advanced measurement algorithms enhance the signal-to-noise ratio by decreasing noise and boosting the signal.
Optional Built-in Ultrasound Biometer
In cases where the optical biometer cannot measure an eye with an extremely dense cataract, the AL-Scan provides an optional built-in ultrasound biometer, allowing measurement of virtually any cataractous eye without having to move the patient. The AL-Scan requires no connection with an external ultrasound unit.

Anterior segment observation with imaging of lens, pupil, and double mire rings
The AL-Scan provides sectional lens image, pupil image, and reflected image of double mire rings projected onto the cornea, which enables the operator to observe the anterior segment.

IOL calculation with its own measured values
Nine IOL calculation formulas are incorporated in the AL-Scan. Once measurement is completed, the IOL power is automatically calculated using its own measured data.
