About the Tango

The World’s fastest SLT & YAG laser

Featuring a patented, proprietary dual-mode laser cavity, Tango combines a full-featured Selective Laser Trabeculoplasty (SLT) laser with a precise, powerful YAG laser for performing iridotomy, helping you manage both Open-angle Glaucoma (OAG) and Angle-closure Glaucoma (ACG). With the industry’s fastest firing rate at 3 shots-per-second (3 Hz), Tango allows you to perform quick and highly-accurate SLT and YAG procedures.

Combination laser system

Both SLT & YAG treatments

Tango provides Selective Laser Trabeculoplasty (SLT) & YAG capabilities in a single, advanced laser system. The system is designed to make procedures as efficient as possible and features a dual-mode laser cavity. It allows you to instantly and reliably switch between SLT and YAG modes at the touch of a button for optimal treatment flexibility and better patient results.

The benefits of SLT...

SLT is a highly-effective approach for first-line glaucoma treatments, adjunct therapy with drugs and alternative therapy when drugs or surgery fail. It is also a flexible treatment option, because it can be repeated, if necessary, depending on the individual patient’s response. SLT uses short pulses of low energy light to target the melanin in specific cells of the affected eye. In response, the body’s natural healing mechanisms rebuild these cells, improving drainage and lowering intraocular pressure. The surrounding, non-pigmented cells, as well as the rest of the eye structure, are untouched and undamaged.

SLT mode

Tango’s SLT mode delivers a gentle, non-invasive approach for stimulating the generation of healthy trabecular meshwork cells and managing intraocular pressure, without the burn and scar tissue associated with other laser procedures.

YAG mode

Tango’s YAG mode features an ultra-gaussian spot profile and fast rise time. These features enable you to perform capsulotomies and iridotomies at lower, more efficient energy levels. They deliver less energy to the eye and allow you to perform capsulotomies with all types of intraocular lenses (IOLs) with significantly less risk of lens pitting. This ultra-low energy optical breakdown (in air) of approximately 1.8 mJ in optimal conditions is compared to conventional YAG lasers that typically achieve optical breakdown (in air) at 3 to 4 mJ.


IOL – friendly Photodisruption

In YAG mode, Tango’s state-of-the-art YAG laser technology provides you with more consistent optical breakdown, which is ideal for meeting new challenges in posterior capsulotomy procedures. You and your patients will benefit from a lower risk of lens pitting, more efficient tissue cutting with fewer shots, delivery of less cumulative energy, and faster procedures.

The Tango allows for creation of controlled capsulotomy openings and a precise iridotomy size.


Capsulotomy for Presbyopic IOLs

A precise capsulotomy is essential for IOLs that correct presbyopia through implantation in the posterior chamber’s capsular bag. Good IOL centration, in terms of the pupil, optimises lens performance. In contrast, decentration can cause halos and poor vision. The goal is a perfectly centred, precise capsulotomy that will not affect the tension of the bag and the position of the IOL in the visual axis. The precision and ultra-low energy optical breakdown provided by the Tango creates a capsulotomy opening that is precisely controlled, without causing damage to the lens, even if the lack of a ridge makes the capsule adhere to the optic.


Iridotomy for Phakic IOLs

Refractive IOLs that are designed to correct myopia or hyperopia (also known as Phakic IOLs) can be placed in front of the iris or between the iris and the natural lens. To prevent any possibility of IOL-induced pupillary block, these lenses require peripheral iridotomies prior to surgery. The iridotomy aperture must be large enough to ensure a balanced aqueous flow, yet small enough so that no light is transmitted back to the pupil, which can cause double vision. Tango enables you to create a precise size of the iridotomy, often in a single shot that uses lower energy than other YAG lasers.

Why choose the Tango?

Designed to maximise your workflow

Ellex has integrated the laser and slit lamp for greater efficiency and reliability, as well as for improved ease-of-use. Tango’s compact, efficient design provides you with additional working space, making it easier to align the patient and to position the contact lens.

In addition, the system is optimised for better viewing, offers pinpoint precision and allows better performance over the long term.

Why choose the Tango?

Minimise system downtime

The system offers the added benefit of convenient, simultaneous access to the patient and laser controls. In addition, it minimises system downtime because there are no exposed fibre-optic or electrical cables to accidentally damage and thereby eliminates the need for you to calibrate the system, or to reposition cables or adapters.

Why choose the Tango?

Optimised for better viewing

The quality and design of Tango’s slit lamp optics are optimised for anterior segment viewing for both SLT and YAG treatment. Featuring Galilean converging optics with a 16° stereoscopic angle, Tango provides a more natural stereoscopic view combined with a shallow focusing depth.

The combination of high-grade crown glass materials and multi-layered, anti-reflection coatings on all optical components maximises light transmission whilst minimising dispersion to deliver better optical performance. In addition, next-generation filter technology provides the best colour-balance possible.

Why choose the Tango?

Better long-term performance

A Q-switch is an optical component used to ‘gate’ energy in order to generate a short, high peak-energy pulse. The Tango’s Q-Switch is thermally matched to deliver a more consistent performance over a number of different operating conditions. This ensures robust, reliable performance and a lifespan of more than 400,000 shots. In addition, Tango’s custom-built YAG power supply incorporates a micro-controller and energy compensation algorithm to deliver greater shot-to-shot consistency.

Why choose the Tango?

SLT pinpoint precision

The Tango’s system electronics, energy attenuator and energy monitor are configured to deliver optimal positional resolution. In addition, an automatic calibration process, combined with start-up and test-fire sequences, uses feedback from the energy monitor in order to constantly adjust the system to ensure a more reliable, stable output.

Parameter settings can be adjusted in 0.1 mJ increments to ensure precise treatment results. This capability, coupled with superior energy control, enables you to deliver highly accurate SLT treatment. All SLT treatment parameters are designed to industry-recognised treatment protocols, maximising treatment options and ensuring effective patient results.

Why choose the Tango?

YAG pinpoint precision

Accurate focusing on the capsule (anterior or posterior) is critical
to preventing IOL pitting. With a tolerance range of ± 8 microns, Tango’s fine, two-point focusing system in YAG mode makes it easy for you to know when you are in focus, ensuring that energy is delivered where you intend in relation to your target.

With a two-point focusing system the two aiming beams converge in the focal plane. This simple, yet highly precise aiming system, is the most accurate at indicating when the laser and slit lamp view are in proper focus, as it allows you to see a separation of the two aiming beams (which indicates out-of-focus) with even the smallest of slit lamp (or patient) movements.

In comparison, four-point and many other focusing systems require a significant shift in the slit lamp’s position before you can distinguish any separation of the aiming beams.

Why choose Tango?

Accurately position optical breakdown

In order to deliver precise treatment and avoid the risk of side effects like IOL pitting, Tango’s continuously variable posterior offset control adjustment (from 100 to 500 microns) allows the most precise adjustment of the plasma ball’s position. Since the plasma ball creates shock waves that move back in the directionof the laser source (that is, towards the operator), the ideal placement of the plasma ball is slightly ‘posterior offset’ from the target tissue to be incised.
