Attributes of the 577 nm yellow laser

The 577 nm yellow laser is minimally absorbed by xanthophyll and is well absorbed by oxygenated hemoglobin compared to 532 nm laser making it the wavelength of choice for lesions close to the macula.

A momentary increase followed by a plateau and an immediate decrease enables rapid and high-power laser emission for the scan patterns.

Multiple scan patterns (available for YLC-500 Vixi)

The YLC-500 Vixi has 22 preprogrammed scan patterns to allow treatment of varying retinal pathologies.

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.

Auto forward (available for YLC-500 Vixi)

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 on adjusting focus.

The repeat mode with the auto forward function enables consecutive regions to undergo photocoagulation on a pre-programmed path by continuously depressing the foot switch. *The auto forward function is available for the equal space (2v2, 3v3, 4v4) and the square (2x2, 3x3, 4x4) patterns. The number of times auto-forwarding can occur differs based on the scan pattern, spot size, and spacing.

LPM* (Low Power Mode) for minimally invasive photocoagulation

LPM is a form of laser photocoagulation that delivers reduced power to the retina for a therapeutic effect. During treatment, the standard (yellow) laser power is decreased by a specified ratio. *Optional software for YLC-500 Vixi only.

Auto forward function

Auto forward function allows automated positioning of the scan pattern for photocoagulation.

Arcade grid scan pattern

In addition to regular mode, LPM includes a scan pattern that prevents treatment in a central circular area within the grid.

User friendly features

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