Nidek AL-Scan Optical Biometry

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

Nidek AL-Scan Optical Biometer

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.

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 with a combined model. The AL-Scan requires no connection with an external ultrasound unit.

IOL power calculation and IOL constants optimization

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

FEATURES

• 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 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.
• The sectional lens image assists in the evaluation of the severity of the cataract. The pupil image assists in the assessment for multifocal IOL.
• The reflected image of mires rings assist in detecting an irregular corneal surface.
• 10 seconds to measure 6 values
• Ability to measure eyes with even dense cataract
• Optional built-in ultrasound biometer.
• Anterior segment observation with imaging of lens, pupil, and double mire rings
• IOL calculation with its own measured values
