Optically Pumped Semiconductor Laser Method

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.

now available with all nidek photocoagulators

Reduce Patient Chair Time with YLC-500 Vixi

Scan delivery units with Vixi enhance treatment by its ability to treat varying retinal pathologies with 22 preprogrammed scan patterns.

Once photocoagulation is completed in one region, the auto forward function automatically positions the scan pattern to the next region of treatment, allowing the surgeon to concentrate better on adjusting focus.


Spacing Function

2v2, 3v3, 4v4, 5v5 – Equal spaces between spots in all direction.


Auto Forward³

Automated positioning of the scan pattern for photocoagulation


Repeat Mode

Regions undergo photocoagulation continuously on a pre-programmed path


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 YLC-500 Vixi / YLC-500 is a yellow laser using the innovative OPSL (optically pumped semiconductor laser) method to achieve stable and reliable laser delivery for optimal treatment outcomes.

Low Power Mode (LPM)

LPM (Low Power Mode) is a form of laser photocoagulation that delivers reduced power to the retina for a therapeutic effect. With LPM, you can treat conditions easily.

Wide Range of
Delivery Unit Options

In addition to conventional single delivery units, the scan delivery units are added to the wide range of yellow laser delivery systems. Both the scan and single delivery units include attachable models³ for the NIDEK SL-1800, ZEISS SL130, and HAAG 900BQ, which provide the existing slit lamps with a new stage for scan and single laser treatment.

¹ For equal space patterns, No. v No. indicates the number of spots in horizontal and vertical directions.
² The arcade grid pattern is used for treatment of the periphery of macula in one-sixth units. The inner diameter is fixed and spot sizes range from 100 to 200 μm.
³ The auto forward function is available for the equal space (2v2, 3v3, 4v4) and the square (2×2, 3×3, 4×4) patterns. The number of times auto-forwarding can occur differs depending on the scan pattern, spot size, and spacing.
⁴ Prior confirmation of attachment to an existing slit lamp model is required.
