LPM (Low Power Mode)

LPM (Low Power Mode) is a form of laser treatment that delivers reduced power to the retina. In LPM, the standard (yellow) laser treatment power is reduced by a specified ratio. Hence, various conditions such as Macular Edema can be easily treated by Grid Laser Photocoagulation.
To use the optional LPM, the MC-500 Vixi has to be equipped with the yellow laser. An additional software upgrade is required.

Arcade grid function

LPM has a grid scan pattern to avoid the central area of the circle, which differs from regular mode.
Selecting the “Pos” (Position) button to align the aiming beam to the foveal center activates treatment that follows the grid scan pattern.


Auto forward function

The auto forward function is available for LPM.

Multicolor on modular architecture

The MC-500 Vixi allows the selection of one, two, or three wavelengths among green, yellow, and red.


Multiple scan patterns

The MC-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*

Once photocoagulation is completed in one region, the MC-500 Vixi allows automated positioning of the scan pattern to the next region to undergo photocoagulation. This feature allows the surgeon to concentrate on focus adjustment.


The repeat mode with the auto forward function enables consecutive regions to undergo photocoagulation on a selected path without repeatedly pressing 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 of the forwarding differs depending on the scan pattern, spot size, and spacing.
