In addition, the ACD measurement range from 1.5mm (to 7.0 mm) that the new A-scan probe allows is particularly beneficial when performing the shallow anterior chamber measurement.<\/p>\n<p>This extremely handy, easy-to-use combination of Biometer and Pachymeter leaves nothing to be desired in comfort and flexibility. Wireless communication, along with the fully integrated IOL power calculation software, enables the complete setup of the handheld device on the PC. The AL-4000 is dockable to the A\/B scanner UD-8000, creating the ultimate ultrasound workstation.<\/p>\n<div style=\"height: 0px; overflow: hidden; padding-top: 56.25%; position: relative; width:
