Eye Cubed Ultrasound Biological Microscope Mode

Ellex Medical Lasers Ltd (Adelaide, Australia) introduced a diagnostic ultrasound mode for its Eye Cubed system at the 2011 American Society of Cataract and Refractive Surgery (ASCRS) annual meeting. According to company literature, with the 40-MHz Ultrasound Biological Microscope (UBM) mode, existing Eye Cubed customers can view various types of pathology at a much higher level of resolution, expanding their anterior diagnostic capabilities when using the system preoperatively for sizing premium IOLs. The UBM’s high frequency, which achieves the optimal level of sensitivity required for viewing the anterior segment, provides improved image resolution and enables the visualization of accommodating IOLs and their movement in situ. The transducer design of the probe, combined with the system’s signal-tonoise ratio, minimizes noise and allows the detection of echoes from the smallest anomalies in the eye.

Keratron Onda

The Keratron Onda (Optikon 2000 SpA, Rome) is a combination corneal topographer and ocular aberrometer that provides refractive and keratometric values as well as corneal and aberration maps of varying pupillary and accommodative conditions. According to company literature, the topographer’s small measuring cone covers 90% of the corneal surface with a double eye position control system for patients with normal and deep eyes. The aberrometer measures accommodation at various distances to compensate for far and near vision, pupil diameter in photopic and mesopic conditions, and pupillary response. The aberrometer also measures visual acuity and simulates quality of vision to better understand the final effect of an IOL on vision. The device measures -20.00 to 10.00 D of sphere and up to 10.00 D of cylinder. The Keratron Onda has an embedded computer and touchscreen monitor, and corneal and aberration maps can be sent electronically via e-mail.
