The design maximizes a surgeon's ergonomic mechanical advantage by eliminating the induced torque that's inherent in conventional flap lifters. The instrument can be used with a central pivoting technique (described in the instructions and video) to further increase its mechanical advantage over conventional flap lifters when flaps are more adherent. Dimensions and torsional rigidity are optimized to transmit surgeon force efficiently with minimal artifactual flex, says the company.
The parabolic-shaped tip allows easy initial insertion under the flap at the hinge. The opposite end of the instrument has a short, rounded tip designed specifically to open the gutter and adjacent flap interface at both ends of the hinge to further facilitate easy initial insertion of the flap lifter. There are two models: 8-16172 in stainless, or 05-7007 in titanium. Contact Rhein Medical at 1 (800) 637-4346.

Acuvue Advance for Astigmatism
Vistakon has introduced the Acuvue Advance for Astigmatism contact lenses. The company reports that the new lenses provide astigmatic patients with excellent visual acuity and exceptional, long-lasting comfort, and make fittings much faster and easier. These toric lenses feature Hydraclear, combining an oxygen-rich material and moisture-rich wetting agent.
Acuvue Advance for Astigmatism's accelerated stabilization design harnesses the natural pressures of the blinking eye to increase stability, preventing the lens from rotating and keeping the lens in its proper position, Vistakon says.
The new design reduces chair time by allowing the lens to settle into place and prevent rotation within one minute. The company calls this accelerated fitting a marked advantage over the traditional toric lens fitting process, which requires waiting up to 15 minutes for the lens to settle before assessing its fit.

3D Anatomy Imager Module
Talia Technology has released the 3D Anatomy Imager module for the RTA. The RTA is a modular scanning laser ophthalmoscope system for the detection and monitoring of retinal eye diseases. The first module made available, in 2004, was the digital fundus imaging module, adding to the system's versatility.
The 3D Anatomy Imager module reconstructs a 3D volume visualization of the 3 x 3 mm acquired by the RTA, using sequential scans. The volume is registered on the fundus image and can be displayed as a raw black-and-white or color-coded image, using algorithms to enhance the inner structure of the retinal layers. The volume can be controlled by cutting, or re-sectioning, zooming and measuring, and provides a number of visual perspectives that would otherwise be unavailable to the practitioner.
Talia says the module allows the user to identify and localize retinal pathology. Cysts and macular holes can be measured, enlarged and examined up close. One can measure the slope angle of the optic nerve head as well as its width and depth. For information, visit talia.com.
