Introduction
The Lumenis
®
Selecta
®
ophthalmic laser system is a fully integrated, high-
performance diagnostic slit lamp and therapeutic laser delivery system. The
Selecta laser family is capable of delivering 1064 nm Nd:YAG and/or 532 nm
SLT laser light. In addition, a Lumenis LaserLink
™
S can be attached to
provide 532 nm photocoagulation when connected to a Lumenis Novus
Spectra
™
laser system.
The Selecta ophthalmic laser family includes the:
• Selecta
®
Duet
™
— a combined 1064 nm photodisruptor and
532 nm SLT laser
• LaserLink S — a slit lamp laser delivery adapter
• Selecta
®
Trio — a Selecta Duet and a LaserLink S with compatible
Lumenis 532 nm photocoagulator
Selecta has all of the standard controls and functions of a diagnostic slit lamp
and is intended for use in eye examination of the anterior segment, from the
cornea epithelium to the posterior capsule.
The Lumenis Selecta is also an ophthalmic surgical laser designed for
performing:
• photodisruption of ocular tissue using laser energy emitted by a
Nd:YAG laser, including
– discission of the posterior capsule of the eye (posterior capsulotomy),
– discission of pupillary membranes (pupillary membranectomy),
– and iridotomy/iridectomy;
• photocoagulation
• selective laser trabeculoplasty
The Selecta produces short, individual pulses of focused laser light with
wavelengths of either 1064 nm or 532 nm, depending on the selected
operational mode. Using a slit lamp microscope and aiming beam, the pulsed
light is accurately targeted on a structure within the patient’s eye.
When the photodisruptor mode is selected, the treatment wavelength is
1064nm. A twin-aiming beam targets the area of tissue disruption.
When the SLT mode is selected, the treatment wavelength is 532 nm. A
coaxial aiming beam targets the trabecular meshwork via a contact lens. The
SLT treatment laser provides a low energy, short pulse of laser light that
produces a thermal effect in pigmented cells in the trabecular meshwork.
If an optional LaserLink S delivery device is attached to the Selecta system and
a Lumenis Novus Spectra 532 nm photocoagulator, the Selecta works strictly
as a standard diagnostic slit lamp—all photodisruptor and SLT laser functions
