Nidek AL-Scan Optical Biometer

Nidek AL-Scan Optical Biometer, 10 Seconds to Measure 6 Values.
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

3-D Auto Tracking and Auto Shot
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

Advanced measurement algorithms enhance the signal-to-noise ratio, which allows the AL-Scan to measure eyes with even dense cataract.

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.

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

The IOL power is automatically calculated after measurement. Calculation of a personalized IOL constant improves postoperative accuracy.

Conventional: SRK, SRK II, SRK/T, Binkhorst, Hoffer Q, Holladay 1, Haigis, Camellin-Calossi

Post-LASIK: Camellin-Calossi, Shammas-PL

Data management and 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.
