Katena Products has released the Giannetti HydroChopper for microincision cataract surgery. The irrigating chopper is designed for both nucleus division and for manipulating fragments within the capsular bag.
Its hourglass-shaped tip features a blunted distal end and semisharp sides to protect the posterior capsule and aid in efficient horizontal chopping. The inside surface of the chopper tip has a concave shape to help capture and control nuclear fragments while feeding the phaco probe.
The HydroChopper’s 20-gauge, thin-walled irrigation tube provides a maximum flow of 65 cc/minute. The instrument can be used in either the left or right hand.
The National Federation of the Blind (NFB) has introduced the Kurzweil-NFB Reader, a device designed to allow users to take pictures of and read most printed materials at the click of a button.
Developed in part by inventor Ray Kurzweil, the portable handheld device utilizes a digital camera, a personal data assistant, character-recognition software, and text-to-speech conversion technology. After passing the device over print, the user hears the contents of the printed document in synthetic speech.
The product allows users to transfer files to both personal computers and Braille notetakers. A headphone jack is included.

Eschenbach has manufactured new hands-free, head-mounted magnifying glasses. MaxDetail glasses provide 2x magnification and can be adjusted so that each eye lens can be focused individually to adjust for ±3 D of spherical correction. In addition to a 20-degree field of view, the MaxDetail features a Galilean telescopic design that allows for a 16-inch working distance.
With a temple length of 135 mm, the plastic glasses weigh in at 49 g and are designed for comfort with flexible plastic temples and a smooth, molded bridge. A carrying case is also included.
The first and second issues of the 2006 Video Journal of Cataract and Refractive Surgery are now available on CD and DVD.
The first issue focuses on cataract surgery. Surgeons from around the world share their approaches to challenging cases of nanophthalmos, relative anterior microphthalmia, mature brunescent cataracts, and Stevens-Johnson syndrome, among others.
The second issue features a host of experts concentrating on complication management. Topics in this installment range from posterior capsular tears and aberrations due to a tilted IOL, to salvaging a sinking nucleus and edge recovery in anterior capsular breaks. The issue closes with a humorous compilation of resident errors.
The Video Journal is published quarterly and is available by subscription.

Enhanced Vision has updated its Merlin LCD desktop video magnifier. Controls are now attached to and move with the pivoting monitor rather than being housed in the unit’s base.
New features also include a three-button control panel and a sliding brightness lever. This computer-compatible video magnifier incorporates a wider field of view with lower magnification (2.7x to 58x). A foot pedal allows for control toggling, and the Merlin Plus remote software provides split-screen capabilities. Voice recognition is optional.
