Effortless Measurement of 6 Clinical Parameters in 10 Seconds
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
3-D Auto Tracking and Auto Shot
The AL-Scan incorporates NIDEK’s much acclaimed 3-D auto tracking and auto shot, enabling accurate measurement with ease and comfort. 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.
Anterior Segment Observation with Scheimpflug Imaging and Double Mire Ring Keratometry
The AL-Scan provides sectional lens image, pupil image, and reflected image of double mire rings projected onto the cornea. 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 mire rings assists in detecting an irregular corneal surface.
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
