YAG & YAG/SLT Laser System + Green Laser Photocogulator YC-200/
YC-200 S plus
GYC-500

Technology

Optional

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).

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”.

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.

¹ A plasma threshold of 1.6 mJ is achieved in ordinary room conditions (in-house data).
² The same laser delivery parameters were used on both samples of photo paper.
³ Data from theoretical simulations.
⁴ SLT Mode available for YC-200 S plus.

SOLIC diagram: with conventional optics the beam is concentrated on the cornea and lens, especially for large spots; with SOLIC the energy is spread more widely there at both small and large spot sizes

Safety Optics with Low Impact on Cornea

All delivery units incorporate the SOLIC optical design that ensures low energy density on the cornea and lens even for large spot sizes.

NIDEK POWERED

Carefully Crafted with High Impact Features

5.7" Color LCD with Touchscreen Control Box

An intuitive graphic user interface and easy-to-read touch screen color LCD allows quick and easy setup and verification of the scan pattern and treatment parameters.

Registration of Contact Lens Magnification

Up to 5 contact lens magnifications can be registered. Confirmation of actual spot size on the retinal surface is easily performed by selecting the registered contact lens.

Pop-up Window

The pop-up window appears once the displayed value, such as 'POWER', 'TIME', and 'INT' is selected. The surgeon can easily make changes to these laser values.

Treatment Summary

Photocoagulation data can be displayed in one screen for review and output in XML format for saving the treatment.

Stored Photocoagulation Data

For flexibility in treating different types of clinical cases, 10 sets of photocoagulation data (power output, emission time, interval time, scan pattern and spacing) can be stored. Each set can be quickly retrieved with one-touch operation.

High Reliability

The GYC-500 ensures stable laser output by using a solid state laser.

Wide Range of Delivery Unit Options

In addition to conventional single delivery units, the scan delivery units are added to the wide range of green laser delivery systems. Both the scan and single delivery units include attachable models⁴ for the NIDEK SL-1800, ZEISS SL130 and 30SL/M, and HAAG BQ 900, which provide the existing slit lamps with a new stage for scan and single laser treatment.
