iMARC Micro-Aspiration
Retinal Cannula
The iMARC Micro-Aspiration Retinal Cannula (iScience Interventional,
Menlo Park, CA) is a micron-scale retinal aspirator designed to aspirate
fluids through a small, self-sealing retinal fistula.
According to company literature, the coaxial
design enables precisely controlled, efficient
fluid aspiration. The iMARC is available in 23-
and 25-gauge platforms with a 30-mm shaft
length. The gap between the microneedle and
the outer shaft produces an annular vacuum to
gently grasp and stabilize retinal tissue to allow
for complete removal of subretinal fluid. The polyimide microneedle has
an outer diameter of 125 μm for self-sealing retinotomies and a beveled
tip to ease entry through retinal tissues. The iMARC can be attached to
any vitrectomy machine or aspiration source for precise surgeon-controlled
aspiration.
RS-3000 RetinaScan
OCT System
Nidek Co. (Gamagori, Japan) announced the release of the RS-3000
RetinaScan System, an advanced spectral-domain optical coherence
tomography (OCT)/confocal ophthalmoscopy device. According to the
company, this device is not currently available
for distribution in the United States. The highspeed
RS-3000 captures 53,000 A-scans per second.
With 4-µm OCT digital resolution, the
device provides high-quality images with speckle
noise reduction. The RS-3000 takes eight types
of scans of the posterior segment and four types
of scans of the anterior segment. Real-time, highcontrast,
and wide view (40° x 30°) confocal
scanning laser ophthalmoscopy accurately
locates the pathology. Other features include advanced autofocus, auto
Z alignment technology, and autotracking. The Navis-Ex software package
allows users to file, manipulate, and analyze images as well as import
them from external devices.
