For surgeons, the attention to detail in new technologies being offered today is allowing them to perform safer, more efficient procedures.
Another injector from MedOne is the Nano Cannula, a 48-gauge metal, beveled-tip cannula that is specifically designed for use in subretinal procedures.
Vortex has designed the Nano Subretinal Gateway Device that is designed to be used in the absence of a vitrectomy. This injector includes a 28-gauge needle, designed for transscleral injections, with an extendable beveled tip, 41-gauge flexible cannula that facilitates injections into the subretinal space.
Larger and smaller forceps handles have been introduced by Alcon, which have been designed for use by surgeons with large and small hands.
The Stiff Dex (Katalyst) is a 19-gauge telescoping stiffening sleeve on a 27-gauge forceps, which allows the forceps to have a much stiffer profile.
The Reddy end-grasping forceps (Bausch + Lomb) features microserrations with a long grasping platform and a window for visualization.
The Sharkskin ILM forceps (Alcon) features laser-ablated microstructures that are 10 x 10 x 5-μm teeth that point toward the grasping edge, which increases the kinetic friction between the forceps and tissue. A second feature is a conforming platform that reduces by 50% the indentation force needed to grasp the ILM. Both features increase grasping ability.
Vitreq now has the 29-gauge Spotlight directional chandelier system that uses a unique fixation system to the drape above the patients brow to direct a wide-view light beam with a 29-gauge trocar cannula.
A membrane-peeling Cannula (Katalyst) has burrs on the lateral edges to cut the ILM and a spatula shape with active extrusion to engage and remove the ILM flap. After removing the membrane, the same cannula is used to perform an air/fluid exchange.
MedOne is reintroducing the 27-gauge VFI Cannula with a Luer lock, which is the only all-metal 27-gauge oil-injection device. It has very thin walls to maximize the internal diameter of the cannula for speedy oil injection.
A 38-gauge cannula designed by Carl Claes, MD, has a 38-gauge tapered tip that is available in 23- or 25- gauge that is used to drain or close macular holes under silicone oil with active extrusion.
The new FDA-approved Leaf Ultracompact Green Laser (Norlase) weighs three pounds and connects to a slit-lamp without any external cables. The laser is controlled wirelessly by a tablet.
Alcon is now offering the Luxor Revalia Ophthalmic Microscope that incorporates an objective lens placed above the light source allowing enhanced depth of field, and three LED options for personalization of the illumination quality: warm cool, or mixed white.
Vortex Surgical now has the EDD (external drainage and depression), a scleral depressor that includes a retractable 28- gauge needle 2.4 mm long and can be connected to active extrusion.
The third scleral depressor, Sclerex from Natalia Vila, is a mechanical scleral depression device that attaches to a lid speculum.
New needle design
Lyubomyr Lytvynchuk, MD, designed a needle to perform intravitreal injections. It has a solid tip that may require less force during injection, and a proximal injection port that may reduce the amount of cellular tissue that is dragged into the eye during injections.
