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.
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.
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.
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.
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.
