Keeler (UK) 3.6v PRACTITIONER Rechargeable Ophthalmoscope with mini charger

The Argos Advanced Optical Biometer is a noninvasive, noncontact device designed to maximize the clini-cian’s ease of use by streamlining biomet-ric acquisition and minimizing discomfort for the patient. The Argos is not yet clini-cally available; however, according to the manufacturer, it outperformed competi-tor devices in clinical trials.1 The Argos consolidates the process of acquiring biometric parameters with a high success rate and accuracy, even in the densest of cataracts. It provides precise ocular biom-etry for accurate selection of IOLs using swept-source OCT.With swept-source technology, a near-infrared swept laser is scanned across the patient’s eye. As light is detected return-ing from boundary layers, an accurate reconstruction of the ocular physiology is created in the device’s software. With the use of fast image reconstruction algo-rithms, real-time 2-D imaging of the eye is available during biometer alignment. Image acquisition for biometric and kera-tometric measurement takes the Argos less than 1 second, according to the company, with the device capturing six images in that span of time and generat-ing three sets of results, calculating aver-age and standard deviation values. The Argos optical biometer is based on coherent optical interferometry and tomography with lateral scanning of a 1-μm swept-source beam. Keratometry (K) values are generated by illumination
