FIBER LASER CAVITY

Stemming from the ELBATM technology, developed and successfully marketed by Quantel laser for various applications, this new generation of laser cavity provides unique advantages:

  • The emission of pure 577nm yellow wavelength
  • LAn excellent beam quality ensuring a homogeneous laser spot profile (top hat)
  • An extended lifetime thanks to a simple, compact and reliable technology

Fully Integrated Design

Easyret® offers a fully integrated design in which the laser and the slit lamp are optimally integrated integrated for better ergonomics and ease of use. It is available with two types of slit lamps to adapt to the operator’s working habits. Both versions feature:

  • an integrated laser adapter featuring a continuously variable parfocal zoom
  • a large touch screen interface to monitor the treatment settings
  • a click wheel to control the patterns settings
  • an intelligent footswitch to control the laser settings

ENHANCED SOFTWARE USER INTERFACE
3 Treatment Modes / 3 Dedicated Targets:

Easyret® provides an intuitive and versatile software user interface simplifying the use of the Single Spot, MultiSpot and SubLiminal™ treatment modes. Built in a clinically oriented manner, Easyret® offers 3 different types of visible targets (aiming beam) facilitating the implementation of the laser spots with each treatment mode.

MultiSpot Mode

Characterized by the use of short pulse durations from 10 to 20 ms, the MultiSpot treatment mode offers many advantages over classical treatments:

  • Less heat diffusion to the retina and choroid, less damage to the retinal nerve fiber layer [3,4]
  • Comfortable treatment better tolerated by patients [5]
  • Treatment time reduction (full PRP in 1 session) [6]

SubLiminal™ Mode

Composed of a train of extremely short microsecond pulses, this SubLiminal™ treatment mode (non-visible laser impacts) is a tissue sparing treatment mode avoiding scarring [7,8] while treating Diabetic Macular Edema [7] and Central Serous Chorioretinopathy [8].

Yellow Laser - 577nm Wavelength

Presented as the most versatile wavelength in the scientific literature, the 577nm wavelength offers the following benefits :

  • Excellent combined absorption by both melanin and oxyhemoglobin (peak absorption of oxyhemoglobin) [1,2]
  • Very little absorption by macular xanthophyll pigments [1,2]
  • Excellent penetration through cataracts and hazy media [1,2]
