Ellex was the first company to pioneer a laser designed specifically for the treatment of floaters. Our Reflex Technology™ makes focusing highly accurate and provides a safe and effective laser-based option to reduce or eliminate visual disturbance caused by symptomatic floaters.


About Reflex Technology

Ellex’s proprietary Reflex Technology™ includes True Coaxial Illumination™, on- and off-axis modes, a precise green aiming beam and a superior energy beam profile — all within a unique slit lamp illumination tower design that converges and focuses your sight line, target illumination and treatment beam into one optical path. This minimizes the potential for focusing errors and the risk of damage to the natural lens or the retina – and provides a safe and highly effective tool for the treatment of vitreous opacities.

See Better, Treat Better

With Ellex’s proprietary Reflex Technology™ visualizing floaters and opacities, and assessing their position relative to the lens or retina, has never been easier.

Treat with Greater Accuracy

Reflex Technology™ allows you to move effortlessly between on-axis and off-axis viewing and provides the highest levels of visualization accuracy and illumination in the anterior and posterior segments, all from one platform.

Lower Energy Treatments

Reflex Technology™ provides higher-power density and precisely controlled plasma formation – the end result is that fewer shots are required to perform treatment with less cumulative energy delivered.

No Missed Shots, Shorter Treatment Times

One of the challenges with LFT is that the high number of shots required can cause the laser cavity to overheat. Reflex Technology™ utilizes a unique method of “Active Cooling” which circulates air throughout the laser cavity to ensure constant cooling, thereby ensuring that the laser works without interruption.

Prevent Post-Capsulotomy Floaters

The benefits of True Coaxial Illumination extend beyond safe treatment of floaters, and in fact help to prevent the notoriously common patient complaint of sudden floater development after capsulotomy.

Featuring coaxial (on) and off-axis illumination, Reflex Technology allows for clear visualization of the internal eye from the cornea all the way to the retina, and as such, provides much-needed spatial context for procedures like laser vitreolysis.

When it comes to the treatment of floaters, precise spatial context is critical. To achieve this, both off-axis and on-axis illumination is required. This ensures that when a surgeon looks into an eye, he or she can clearly establish where the lens, floater and retina lie in relation to the floater and to each other.

On Axis Mode

  • Provides enhanced visualization of the middle and posterior vitreous
  • Allows for spatial context – especially near the retina
  • Red reflex helps with contrast for certain floaters
  • Ability to view anterior floaters

Off Axis Mode

  • Beneficial for visualizing anterior floaters
  • Minimizes red reflex which allows for floaters to appear “white”
  • Helps with defining posterior capsule
  • Decreases glare in some situations

Laser Floater Treatment Through a Multi-Focal Lens


I’m always amazed how symptomatic patients are from floaters. I ignored them in the past, and it’s just been amazing to me to learn how debilitating they can be for certain patients.

Ivan Mac, MD, MBA (USA)

Three years of personal experience with Reflex Technology™ has shown me how titratable illumination - True Coaxial Illumination - can customize a surgeon’s visual experience during surgery. Because the illumination level provided with Reflex Technology™ is adjustable, it is possible to precisely titrate the amount of coaxial illumination as needed.

Many times, we can see the shadows cast from the floater, which I think is important. By showing patients that they have a problem, it solidifies their understanding and desire for treatment.

Reflex Technology Versus Conventional YAG Laser Technology

Designed for capsulotomy and iridotomy procedures only, traditional YAG lasers typically have larger and less-controlled plasma with more inconsistent power output. Further, these conventional YAG lasers deliver the illumination and laser from a low, non-coaxial position with larger convergent zones, making it extremely difficult to target and treat floaters. Since it can be difficult to focus on vitreous strands and opacities when using these systems, collateral ocular tissue damage may occur. Further, the greater cumulative energy delivered poses a significant risk of damage to surrounding ocular tissue, as well as of side effects such as cataract and intraocular pressure (IOP) spike.


  • Lack of visualization in the posterior segment
  • Inefficient energy beam: higher cumulative energy delivered to patient
  • Number of shots not sufficient: the high number of shots needed during LFT i.e. 300, requires a superior laser cooling mechanism not available in conventional YAG lasers


  • Ultra Gaussian beam profile: allows for non-linear rise in energy with minimal disruption of surrounding tissue
  • Tightly controlled plasma
  • Less cumulative energy delivered to patient
  • True Coaxial Illumination: allows for visualization beyond the posterior capsule
  • Ability for “on” and “off” axis visualization: helpful for visualising both posterior and anterior floaters
  • Active Laser Cavity Cooling System
TCI is the heart and soul of this laser. It is what makes this system different and enables us to perform YAG vitreolysis with confidence.

Paul I. Singh, MD (USA)

For years, I had been dismissive with many patients who had floaters, just as Dr. Shah described. Once I started listening to their symptoms, I realized that floaters were impacting their quality of life, so I decided to try vitreolysis.

Michael Tibbetts, MD (USA)

Modern laser floater treatment is a different procedure. It is not the same procedure as in past years. Earlier attempts at treating floaters were not always positive, because the technology was not optimized for the procedure.

Karl Brasse, MD, MRCOphth (Germany)

Improve Patient Life Quality

While floaters can be overlooked as a common symptom of vitreous deterioration, the adverse effect that they can have on a patient’s quality of life is sometimes significant enough to warrant treatment. A study of over 300 outpatients reported that floaters had the same negative impact on quality of life as age-related macular degeneration*.

Laser floater treatment can significantly improve a patient's perception of their everyday visual functionality and provide them with much-needed relief from eye floaters. The technique fills the treatment gap for patients whose symptoms and risk profile does not warrant treatment with vitrectomy. Laser floater treatment can also delay or obviate the need for surgery.
