New Silicone Hydrogel Comes to United States
CooperVision has launched its silicone hydrogel lens Biofinity for daily wear in the United States. Designed with patented Aquaform technology, Biofinity monthly replacement lenses are manufactured in comfilcon A, which offers higher water content, lower modulus and high oxygen transmissibility, according to the company.
COOPERVISION'S NEW SILICONE HYDROGEL BIOFINITY IS NOW AVAILABLE IN THE UNITED STATES.
CooperVision further states that the Aquaform technology establishes hydrogen bonds with water molecules to create a naturally hydrophilic material that retains water within the lens. In addition, wettability is inherent within the material itself, eliminating the need for additives, coatings, wetting agents or surface treatments, according to CooperVision.
The water content of Biofinity is 48 percent, with a Dk of 128 and Dk/t of 160. Parameters include sphere powers from –0.25D to –6.00D, 8.6mm base curve and 14.0mm diameter.
In other CooperVision product news, the company has expanded the parameters of its Proclear Multifocal Toric. The lens is now available in sphere powers from +20.00D to –20.00D (0.50D steps after ±6.50D), cylinder powers of –0.75D to –5.75D in 0.50D steps, axes in five-degree steps, add powers of +1.00D to +4.00D in 0.50D steps and base curves of 8.4mm and 8.8mm.

Reichert, Inc. has released the Tono-Pen Avia Applanation Tonometer, an applanation tonometer that's small enough to fit in a shirt pocket yet filled with advanced technology, according to Reichert.

Reichert claims that new features allow operators to take fast and accurate IOP measurements with minimal training. The instrument is designed to function in any position.
Tono-Pen Avia utilizes micro strain gauge technology and a 1mm diameter transducer tip. The average of 10 independent readings, combined with a statistical coincidence index, ensures accurate and repeatable results, according to Reichert. Call (716) 686-4500 or visit www.tonopenavia.com.
