Topcon announces new wavelength in Pascal pattern scanning laser
VIENNA, Austria — Topcon announced a longer wavelength of 577 nm in the Pascal Streamline 577 at the European Society of Cataract and Refractive Surgeons meeting here.
The device combines the "optimum 577 nm wavelength" to its configuration, a press release from the company said. The device uses lower power and shorter pulses for reduced pain and trauma.
"The longer wavelength of the 577 better targets the [retinal pigment epithelium] with less scatter than the 532 [nm] or 561 nm lasers. The combined absorption by both melanin and the oxyhemoglobin makes the 577 more efficient. Energy is concentrated to a smaller volume, allowing use of lower powers and shorter pulse durations," the release said.
It is usable in the treatment of open-angle glaucoma and offers enhanced retina patterns. It also provides printed reports of each procedure performed.
