Lightmed TruScan Pro - Clinical Use General Warnings

LIGHTMED TruScan Pro – Operator’s Manual Rev. No. 01 Page 96 of 109
• Aphakic eye with vitreous in the
anterior chamber.
• Neovascular glaucoma.
• Glaucoma caused by congenital
abnormalities of the angle.
• Glaucoma secondary to active
uveitis.
Less than 90° of open angle or
extensive low-lying peripheral anterior
synechiae around the circumference of
the angle.
LIO
• Proliferative and non-proliferative
diabetic retinopathy with pathology
outside the arcades.
• Retinal tears.
• Lattice degeneration.
• Localized retinal detachments.
• Any eye requiring laser treatment
out of the ora serrata.
• Delivering laser treatment through
small pupils or to eyes with semi-
opaque focal lenses.
• Treatment sites close to the
macula, within the arcades or where
precise positioning of the laser is
not possible, should not be
attempted.
• Opaque cornea or lens, or blood in
the vitreous humor that interferes
with the laser delivery to the tissue
requiring treatment by scattering
the beam.
• Do not treat albino patients that no
pigmentation.
Endoprobe
• During vitreous surgery to produce
a chorioretinal scar around retinal
breaks or retinal sites.
• To perform platelet-rich plasma
(PRP) in proliferative diabetic
retinopathy.
• To perform intraoperative PRP on a
scleral buckle.
• To perform intraoperative PRP
around focal neovascularization.
• Do not treat albino patients, or eyes
that have no pigmentation.
6.2 Clinical Use General Warnings
• Doctors should ensure that they have extended training before attempting to carry out any of
the indicated procedures. Doctors will take full responsibility for the setting of the laser unit
operating characteristics, techniques, and methods used during treatment. They must use
their own clinical judgment in determining all aspects of the treatment performed.
• For all types of LDUs, always ensure that the power levels are not initially set too high. Always
set the power levels according to the tissue effects. Remember that highly vascularized and
pigmented tissue will require less power than their lightly pigmented counterparts.
• The aiming beam and yellow or infrared laser beams are coaxial. If there is any distortion to
one of them, then the other may also be distorted. This can lead to inconsistent tissue effects
and clinically unsatisfactory results.
• By reducing the spot size in half, the power density will increase by a factor of four. Be very
careful not to deliver too much power to the site.
