The Nidek YC-200S, the successor of YC-1800, is a combination laser Yag & SLT that  incorporates a suite of technological innovations:

• SLT mode
  The YC-200 S plus offers an advanced SLT mode. SLT is highly effective for treating open angle glaucoma.
  The SLT-NAVI feature presents an intuitive display on the progress of laser treatment, providing the surgeon with important feedback.
   
• Refined laser delivery with lower energy
  The YC-200 S plus / YC-200 achieves 1.6 mJ plasma threshold in air*1, delivering accurate and robust treatments with lower energy.
  *1 A plasma threshold of 1.6 mJ is achieved in ordinary room conditions (in-house data).
   
• Clear and sharp field of view
  An improved optical design that optimizes resolution and contrast, and an expanded focal depth provide a clear view of pathology and treatment. A unique illumination system with an LED light source results in a bright, near-natural view that minimizes aberration. The sharp, clear optics provide an enhanced view of the treatment area.
   
• Precise aiming beam
  Motorized rotatable aiming beam (YAG mode)
  The dual aiming beam offers superior targeting with a 360° rotating aiming beam that can avoid corneal opacities and achieve more accurate focusing
   
• Optimized operating distance
  Maximized working distance allows easier manipulation of the contact lens, and the short operating distance decreases surgeon fatigue during treatment.
   *Operating distance denotes the distance from the microscope eyepiece to the patient’s eye
   
• Unique joystick: Utility S-switch
  The S-switch on the joystick changes treatment settings without shifting gaze from the oculars. The ease of use allows surgeons an increased level of comfort during treatment.
