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

SureSpot™ OpticsSureSpot™ Optics
The unique and patented SureSpot optics technology from Lumenis ensures that the focal point of the laser beam is maintained on the retina while power density on the cornea and lens is minimized for increased safety.



SureSpot optics also creates a true 50-micron laser spot; that capability distinguishes the Lumenis technology from other lasers that may have a 100-micron minimum spot size and/or project a fuzzy laser spot on the retina.

In essence, SureSpot optics improves treatment efficacy and precision while reducing the potential for damage to anterior-segment tissues. The latter occurrence is especially a concern when using wide-angle lenses that enhance light uptake by the cornea and lens. more

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
CaseSaver™ mode
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.

User-Friendly
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

ClearView™ Filters
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.
