General Intended Use
The Lumenis Selecta is a fully integrated, high-performance diagnostic slit
lamp and therapeutic laser delivery system. 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. It is used to aid in the diagnosis of diseases or trauma which
affect the structural properties of the anterior segment.
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;
• 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. The
energy contained within a single short pulse is concentrated by focusing to a
very small spot size so that plasma formation occurs at the focal point. This
creates an acoustic wave that disrupts nearby tissue.
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 compatible Lumenis 532 nm photocoagulator laser, such as the Novus
Spectra, the Selecta works strictly as a standard diagnostic slit lamp— all
photodisruptor and SLT laser functions are disabled. The LaserLink S laser
delivery adaptor is used for treatments specifically cleared for the compatible
laser photocoagulator.
Practitioners must take precautions to prevent exposure of laser energy to the
eyes and skin from either direct or diffusely reflected laser beams, except as a
therapeutic application. Additional precautions must be taken to prevent fire,
electrical injury, and explosion.
