Automatic Retinal Imaging Camera
Simplify your posterior segment documentation with a new camera that offers automatic alignment, centering, focusing and capture of color retinal images: the new TRC-NW400 non-mydriatic retinal camera from Topcon Medical Systems. Once the first eye is photographed, the camera automatically repositions to take a picture of the other eye. The device is DICOM compliant for simplicity of image sharing. Save your images to a remote or electronic medical record server, or a USB drive and print them from a USB port.
The device fits against a wall or corner and can be operated from any angle with a rotating touch panel. The photographer sits in the front, behind or side of the machine.
New Slit Lamp Design
Reichert Technologies has released a new slit lamp, the Xcel 455, that steps up illumination and magnification of patients’ eyes.
The eyepiece has a 12.5x magnification and the optics feature lenses with multi-layer optical coatings that provide bright, clear illumination, the manufacturer says. The device also boasts red-free, heat-absorbing, cobalt blue and neutral-density filters.
The Xcel 455 is currently available in Canada, Europe and various countries in the Middle East, Latin America and Southeast Asia; US availability is expected in late 2014.
Entry-level SD-OCT Model
At Vision Expo West, Optovue rolled out its newest SD-OCT device, the iScan, which performs 25,000 A-scans per second and features an image resolution of 5.0µm. Voice prompts guide the patient through the exam. Positioned for routine screening, the device generates what Optovue calls an iWellness scan, consisting of a cross-sectional retinal scan, a retinal thickness map and ganglion cell complex map. Results are compared to a normative database to gauge the risk of disease or presence of ocular anomalies.
The iScan is an entry-level, more affordable cousin of the company’s iVue SD-OCT. Although currently geared only for iWellness scans, the platform is upgradable, Optovue says. With the focus on screening and wellness, patients should expect to pay out of pocket for scans using the device.
Presbyopic Contacts with Expanded Parameters
A new contact lens for presbyopes, the Duette Progressive from Synergeyes, features greater add powers to help patients who don’t see well enough with soft multifocal contact lenses.
Practitioners can customize the lenses for each patient with a choice of three add powers (+1.00, +1.75, +2.50) and 0.1mm base curve increments for a proper fit. The lenses have 3.00mm near center aspheric add zones and aspheric distance optics for progression of powers from far to near.
The gas permeable design delivers clearer vision than soft lenses, particularly for astigmats, the company says. After establishing the GP base curve, the lens fits like a soft contact. The 84 Dk/t silicone hydrogel skirt and 130 Dk center block UV rays and allow oxygen permeability and comfort.
High Cyl Correction in a Stock Lens
In a first for silicone hydrogel torics, Acuvue Oasys for Astigmatism lenses now come with a new -2.75D cylinder option that does not require a special order, says Johnson & Johnson Vision Care. Options now include -6.00 to +6.00 in 0.25D steps (cylinders: -0.75, -1.25, -1.75, -2.25, -2.75; axis: full circle in 10° steps) and from -6.50 to -9.00 in 0.50 steps (cylinders: -0.75, -1.25, -1.75, -2.25, -2.75; axis: full circle in 10° steps).
