EASYRET Multispot & Subliminal™
Stemming  from the  ELBA™   technology,    developed    and  successfully  marketed   by Quantel   Laser for various  applications,  this  new generation   of laser cavity  provides  unique  advantages:
 
An  excellent    beam  quality   ensuring   a homogeneous    laser  spot profile  (top  hat)
- The emission  of pure 577nm yellow  wavelength
- An extended  lifetime  thanks  to a simple,   compact   and  reliable technology
 
The fiber  laser  technology    is a variation   of the standard   solid-state laser  technology. In fiber lasers, the  lasing   medium   is  composed    of  an  optical   fiber doped  with  rare earth elements    and  optically    pumped   by diodes.


MultiSpot Mode:
Characterized    by the  use of short  pulse  duration's from 10 to 20 ms, the Multi Spot 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]
The  MultiSpot  treatment  mode  can  be delivered  through 5 customized   patterns for better  adaptation to the treatment  site.
Single   spot-   Squares    - Circles  - Triple   arcs - Macular   grid

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]
 
Subthreshold Technology:
 
In  addition    to  SingleSpot    and  MultiSpot    delivery   modes.   Easyret® features   the  Subthreshold   technology
 
The  use  of this  subthreshold    treatment  mode converts   each  laser shot  into  a "pulse   envelope"    composed    of  a customized    train of short  pulses,  allowing    the operator  to fully adjust  the  pulse duration (On  Time)   and   interval   (Off Time).  This fined-tuned     control  of  the laser treatment   settings ensures  a precise  management   of the thermal effect on the targeted  tissues.

Resume® Technology:
 
Easyret®features   the proprietary   Resume®   function offering  more  flexibility   to the operator  in the implementation     of the  MultiSpot    and  the Subthreshold     treatment  modes.
 
-  In MultiSpot   mode, the  pattern  delivery  can  be paused  and resumed  (the  previous   shots  are remembered)
-  In Subthreshold     mode, the treatment  is combined   with  the  pattern  scan mode and delivered semi-automatically   in several  steps

Sub-threshold Mode - Tissue sparing treatment mode avoiding scarring
Composed of a train of extremely short microsecond pulses this sub-threshold treatment option is generating more and more interest among retinal physicians:
  • It affords new laser treatment options for many pathologies such as diabetic macular edema, central serous retinopathy
  • It can be combined with the pattern scan mode for an easier and better treatment delivery
