O2 Optix Approved for Extended Wear
CIBA Visions O2 Optix silicone hydrogel daily wear contact lenses are now FDA-approved for up to six nights of extended wear. O2 Optix lenses have been available since September. They are made of lotrafilcon B, which has a 33% water content and a Dk/t of 138 at 3.00D. The lenses come in an 8.6mm base curve and are available in powers 1.00D to 6.00D (in 0.25D steps). The company expects to expand the power range next year and says it is developing a toric version of the lens.
In other news, CIBA Vision says its Focus Dailies Toric will be available in expanded powers in January 2005. The new power range is +4.00D to 6.00 (in 0.25D steps), 6.50 to 8.00 (in 0.50D steps) and plano. The lenses come in 0.75 cylinder, axes 90 and 180 and an 8.6mm base curve.

Confocal Laser Microscope
The Confocal Laser Microscope, from Heidelberg Engineering, displays a patients cornea via laser scanning technology. The microscope combines the companys HRT II laser scanning technology and the Rostock Cornea Module, which received FDA clearance in October, to display magnified images of the corneas internal structures. This lets you view the corneas cell layers and individual cells digitally or in movie format.
The company claims corneal diseases that previously were difficult or even impossible to see may now be viewed, and that the Confocal Laser Microscope may be particularly useful in recognizing parasitic infections that affect long-term contact lens wearers. Call 1-800-931-2230, or go to www.heidelbergengineering.com.
The Falcon 418 pachymeter, from Talia Technology, uses ultrasound technology that incorporates a continuous (analog) measurement that can capture corneal thickness readings at high resolutions. The resolution for a single internal measurement is 0.22m.
Field Test Cards
New field test cards from IXMUS LLC are designed to detect macular and neuro-ophthalmic disease. The following tests are available: blue-on-yellow, blue-on-red and white-on red background Amsler grids and combination red dots.
IXMUS LLC says the cards use high-resolution grid patterns with low, intermediate and high contrast. The grid patterns employ both the background color and grid lines to pick up five decibels of shallow scotomas, which cause color desaturation. The field test cards are foldable and can be used either in an office setting or by patients at home for self-monitoring purposes.
The cards come with instructions and references printed on the cover. Call (508) 464-0540, or go to www.ixm.us.
New Glass Gonio Lens
Volk Opticals G-Series line of glass gonioscopy aspheric lenses has a new addition: the G-4 two-in-one gonio nf (no flange/no fluid) lens with interchangeable handle. Rotate the G-4 gonio nf lens slightly and four precisely angled 64 mirrors allow you to visualize the entire anterior chamber angle. Viscous interface solutions, such as methylcellulose, are unnecessary with the G-4, the company says. Only artificial tears or a thick natural tear layer are needed for patient comfort.
The G-4 comes with an interchangeable handle that can be easily removed and reattached to create a straight or 45 angled handle to accommodate individual patients clinical presentations. Call 1-800-345-8655, or go to www.volk.com.

Updated Color Coding Computer Label Program
Ancom Business Products introduces Smeads Smart- Strip 2.0, an updated version of its color-coding label software designed for end-tab patient charts. This new version features a drag-and-drop feature that lets you or your staff reposition the color blocks (a square that corresponds with the color or number that identifies a chart as belonging to the patient.) The company says this feature enables more practices to match the programs colors with their existing end-tab color schemes. The new software also allows you to choose from a variety of label styles.
Smart Strip 2.0 allows staff members or practitioners to type in patient information, and then print color-coding information, numeric or alpha color blocks, barcodes, custom text, year labels and more on a single label. Eight bonus labels are included on every Smart- Strip label form for index tabs or any other use you choose. (The software requires SmartStrip label forms.)
