Anterior segment treatment mode for

Laser Peripheral Iridotomy

The intuitive anterior segment mode for Laser Peripheral Iridotomy (LPI) for Navilas® 577s supports the therapy of narrow-angle glaucoma and thus can contribute to the reduction of intraocular pressure.

Iridotomy treatment of narrow-angle glaucoma with the Navilas 577s retina laser

Laser Peripheral Iridotomy – how it works

The Navilas® 577s software 3.5 and higher enables the user to intuitively switch from retina treatment mode to the new anterior segment treatment mode which as a first step supports Laser Peripheral Iridotomy (LPI).

This software is designed for combination therapy with a standard iridotomy ("Abraham") lens with 0.63x laser spot magnification.

LPI allows the physician to prepare the iris with the Navilas® 577 nm yellow laser. After the initial treatment with Navilas®, the physician can complete the iridotomy treatment with less complication (bleeding) using a separate YAG laser. This combination therapy is a common procedure.
