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.
9 Calculation Formulas
for Intra-Ocular Lens Power
Quickly calculate IOL power with AL-Scan's 9 embedded IOL calculation formulas¹, improve postoperative accuracy with IOL Constants Optimization.
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.
Data Management & IOL Power Calculations
The large storage capacity of the NAVIS-EX database is available for review on the AL-Scan Viewer. The basic functions of the AL-Scan can also be performed with the AL-Scan Viewer including IOL power calculations and optimization of IOL constants.
Toric Lens Assist Function
Acquisition of multiple toric lens assist images allows selection of the optimal image for digitally marking the astigmatic axis. These images allow better surgical planning for accurate toric IOL alignment.
Recalculations of Measured Values
The AL-Scan Viewer allows recalculation of modified axial length, white-to-white, and pupil size data for accurate calculations.
Optional
