Eschenbach Gets Bigger and Brighter

Eschenbach has expanded its line of Bright Field stand magnifiers by introducing a new smaller lightweight version. The new 1424 offers 1.8× magnification and is 45 mm in diameter, nice and compact. Like the other magnifiers in this line, the 1424 is designed to gather light, thereby creating a brighter image through the lens. The lens is made of acrylic material, not glass, making it lighter in weight, and includes Eschenbach’s unique cera-tech coating. In addition, a black mount around the edge keeps the side of the magnifier clean and free of fingerprints. The mount also holds the bottom surface of the lens off the object being viewed, eliminating scratches caused by the object or reading material.

ChromaGen lenses were developed from the concept of altering the spectral energy composition of the retinal stimulus, balancing out the deficiencies of brightness, hue, and saturation to balance color vision. They are manufactured based on proprietary processes and were recently award FDA approval, as well as a U.S. patent. ChromaGen is also available in the spectacle glass for those patients that cannot adapt to soft contact lenses.

TLC and Alcon Expand Alliance

As part of a multi-year technology alliance with Alcon, TLC Laser Eye Centers have adopted the next generation of flying-spot small beam technology offered by the Alcon Summit Autonomous LADARVision system as its primary platform in its North American refractive centers. TLC centers already use a variety of Alcon-manufactured surgical instruments, accessory products, and prescription drugs. The LADARVision system has been approved by the FDA for using the LASIK procedure to treat myopia with or without astigmatism, hyperopia with or without astigmatism, and mixed astigmatism. In addition to being the only FDA-approved laser to achieve all these indications, the LADARVision system is the only FDA-approved laser system to combine laser radar eye tracking with narrow beam shaping technology during surgery.
