Lumenis Multicolor Photocoagulators
Addressing the specific clinical needs of your patients
The Novus® Varia™ multicolor photocoagulator enhances the physician’s ability to treat patients by utilizing wavelengths with different light absorption characteristics - specifically targeting the three endogenous chromophores that are of primary relevance in retinal surgery: melanin, hemoglobin, and xanthophyll.
With the ability to choose from multiple colors of light that also differ in their penetration characteristics, the Novus Varia allows the retinal specialist to select a specific wavelength that will reach and be maximally absorbed by the target chromophore while minimally absorbed by competing chromophores.
The result is a customized laser treatment with optimal clinical outcome and fewer side effects.
|Green (532 nm)
|Green laser light is a clinically-proven wavelength that is excellent at targeting the melanin-containing retinal pigment epithelium (RPE), through clear ocular media. It is well suited for a variety of retinal treatments in which melanin is the target chromophore, such as pan-retinal photocoagulation (PRP).
|Yellow (561 nm)
Yellow laser light offers the clinician maximal absorption in hemoglobin with zero or negligible absorption in macular xanthophyll.
In addition to easily penetrating through nuclear sclerotic cataracts, the yellow wavelength is desirable when it is necessary to penetrate through fluid, such as when treating a retinal detachment or tear. It also penetrates mild pigmentary disturbances and so is well suited for conditions where the target lies in a region of previous photocoagulation treatment.
One of the main advantages of yellow laser light stems from the fact that it approximates the peak absorption of hemoglobin, but it is not highly absorbed by melanin in the retinal pigment epithelium (RPE) or xanthophyll in the neurosensory retina. Therefore, it is recommended for focally treating extrafoveal microaneurysms or other vascular lesions in the macular region that may cause macular edema.
In addition, yellow laser produces significantly less light scatter, allowing for more efficient treatment and requiring lower energy levels to achieve desirable clinical outcome; this creates significantly less discomfort for the patient during and following the laser procedure.
|Red (659 nm)
|Red laser light offers excellent penetration through hemoglobin, making it the wavelength of choice in
situations where it is necessary to penetrate through preretinal, subretinal or intraretinal hemorrhage.
It is also the optimal wavelength for achieving deeper penetration into the choroid to treat chocoidal
melanomas or other deep pigmented lesions.
It is also the preferred wavelength for treating infant eyes with ROP because it penetrates through the tunica
vasculosa lentis, the vascular network surrounding
Sharply defined and evenly distributed power on the retina; Safe & low-power density at the cornea and the lens
Superior Optics you can trust
Homogeneous laser spot at target tissue
Our advanced optics and laser delivery technology features uniform energy distribution across the entire laser spot area for more precise and safer treatment.
Dependability you can count on
In the unlikely event that one of the laser wavelengths were to become inoperable, the other two wavelengths will remain operational – allowing you to keep on treating your patients until the unit is promptly serviced by a qualified Lumenis Engineer – part of the largest service network in the industry.
Convenience & Flexibility
Dual Fiber Port
Changing delivery devices is fast and easy. The Novus Varia automatically senses the delivery devices connected to it. Laser parameters are adjusted internally to compensate for the chosen delivery device to maintain selected power density on the target tissue.
Touch screen & remote keypad
A color touch screen and illuminated remote keypad put all operations literally at your fingertips.
The Lumenis *PowerEase™ footswitch provides hands-free power adjustment.
The Lumenis *Smart™ footswitch contains an integrated proximity sensor which inserts and removes the physician eye safety filter at the moment you slide your foot in and out of the footswitch housing.
* Optional accessory
Optimized view of treatment site
The Lumenis ClearView™ filters’ photopic balanced coating eliminates color distortion of the treatment site while optimizing white light transmission or “brightness” of the physician’s view.
Compatibility with a wide variety of delivery devices
The Novus Varia is compatible with a wide variety of accessories and delivery devices – meeting your specific preferences in the outpatient clinic and the OR.
Choose from a comprehensive selection of endophotocoagulation probes along with different LIO models and Slit Lamp LaserLinks.
Caution: Federal (US) law restricts Lumenis devices to sale by or on the order of a licensed practitioner.
