Advanced YAG and SLT Combination Laser System

NIDEK | Coaxial Illumination Tower

Coaxial Illumination Tower

The YC-200/YC-200 S plus is capable of seeing and illuminating opacities in the vitreous with NEW optional coaxial illumination tower, which makes visual axis and illumination axis coaxial. The tower optimizes visualization during posterior membranectomy, capsulotomy and iridotomy and also illuminates vitreous opacities with the on axis/off axis illumination.*


Combo YAG/SLT/Green

The YC-200/YC-200 S plus can be easily connected to NIDEK’s Green Laser Photocoagulator (GYC-500), allowing treatment of a wider range of patients and indications. Space requirements are minimized, and the NEW optional combination adapter includes an illumination tower (split mirror illumination).*

Comparison of Laser Energy Spots²

Refined Laser Delivery
with Lower Energy

The YC-200 S plus / YC-200 achieves 1.6 mJ plasma threshold in air¹, delivering accurate and robust treatments with lower energy.

Precise Treatments

A suite of technologies has been incorporated in these lasers to achieve seamless function and greater precision. Features for targeting pathology, accurate energy delivery, and operative assist functions allow the surgeon to deliver treatments “Right on the Mark”.

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.

Cornea-friendly SLT

With a 5.5° cone angle, the YC-200 S plus is designed to decrease energy density on the cornea for sparing tissue from repeat treatments. The energy density on the cornea is reduced by more than one-third with a 5.5° cone angle compared to a 3.0° cone angle.

Exact Targeting

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.

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.

Precise Edge Aiming Beam

SLT Mode

Parfocality delivers a clear view for easier focusing of the aiming beam through the contact lens.

Wide Range of Focus Shift

The focus shift enables a 500 µm anterior or posterior axial shift of the focal point of the YAG laser. A change in 25 µm increments achieves precise treatments irrespective of the severity of pathology.

Smooth Operation Workflow

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.

Key Card Functionality
Control Box

An intuitive graphic user interface and easy-to-read touch screen color LCD allow quick and easy setup and verification of treatment parameters. An SD card starts the unit, enables software upgrades, and saves treatment summaries.

Optimized Operating Distance
Slit Lamp

Optimized 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.
