Detailed Information
6 clinical parameters in 10 seconds
| In 10 seconds, six values for cataract surgery are measured:
– Axial length |
 |
In addition to cataract surgery planning, the addition of optional Myopia Viewer MV-1 software allows myopia management.
3D auto tracking and auto shot
| The 3D 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.
Sectional lens image (Scheimpflug image) |
Pupil image |
Reflected image of double mire rings |
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.

Additional features with AL-Scan Viewer for NAVIS-EX* (optional)
AL-Scan Viewer is software used for viewing and working with AL-Scan data via NAVIS-EX. This function enhances the capability of the AL-Scan with additional features and increases the efficiency of any clinic.
* NAVIS-EX is optional software and is required for use of the AL-Scan Viewer.
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. |  |
Recalculation of measured values
| The AL-Scan Viewer allows recalculation of modified axial length, white-to-white, and pupil size data for accurate calculations. |  |
Optional Myopia Viewer MV-1 software for myopia management
Adding the optional Myopia Viewer MV-1 software will expand your clinical services for monitoring and managing myopic progression in young patients.
Measurements over time can be monitored and compared with the growth curve* (trend data). The MV-1 software allows clinicians to evaluate progression of myopia compared to an age-matched population and extrapolate progression based on growth curves.
