Pattern Scanning Laser Trabeculoplasty (PSLT) (optional)
Indications for Use:
Pattern Scanning Laser Trabeculoplasty (PSLT) software is intended for use with the
PASCAL Synthesis for procedures in trabeculoplasty in Open Angle Glaucoma.
Description:
Pattern Scanning Laser Trabeculoplasty or PSLT is an advanced tissue-sparing laser
treatment for reducing intraocular pressure. PSLT provides a rapid, precise, and
minimally traumatic (sub-visible) computer-guided treatment that applies a sequence
of patterns onto the trabecular meshwork. Automated rotation of consecutive patterns
ensures that treatment steps are precisely placed around the trabecular meshwork
without overlap or excessive gaps.
When the PSLT pattern is selected, the pattern is delivered when you depress the footswitch,
after which the system automatically rotates the pattern clockwise. If the 360- degree treatment
plan is selected, the pattern rotates a full 360 degrees before treatment is automatically
terminated. If the 180-degree treatment plan is selected, the pattern rotates 180 degrees before
treatment is automatically terminated.
Establish starting location for PSLT pattern.
Titrate to set desired Power.
Align to trabecular meshwork using <Curvature>.
“<Treatment Complete>” displays in the < PSLT Treatment> window, and the system enters
STANDBY mode. Press <OK> to return to the Anterior Treatment screen.
Additional treatments can be initiated after returning to the Anterior Treatment screen.
