The OPTICAL BIOMETER AL-Scan is a measuring device that can measure as a single unit the values necessary to calculate the power of an IOL for cataract surgery such as axial length, corneal curvature radius, and anterior chamber depth. It measures these necessary values successively through a non-contact optical measurement method. An optional A-scan probe is also available to scan axial length with an ultrasonic measurement function by touching it to the cornea should optical measurement not be successful. In addition, an anterior eye segment image overlaid with the corneal meridians can be created as a reference for toric IOL implantation. The AL-Scan also has the function to calculate the power of an IOL using measured values such as axial length.
