Coherent, Selecta 7000 SLT Glaucoma Ophthalmic Laser System w Factory Table

The Selecta 7000 is the original SLT Laser, built from the legendary 7970 Yag
This model offers similar incredibly reliable characteristics at an SLT wavelength
The Coherent Medical Lumenis Selecta 7000 is an SLT (Selective Laser Trabeculoplasty) system using a frequency-doubled, Q-switched Nd:YAG.
Delivers single pulses of 0.1 to 2.0 millijoules per pulse with a pulse duration of approximately 3 nanoseconds.
Low energy, short pulsed treatment confines thermal damage to cells containing the target pigment or chromophore.
In the case of trabecular meshwork, this target is represented by the pigmented cells.
The nanosecond pulse duration is also an important factor in preventing collateral and coagulative damage
Designed to perform selective laser trabeculoplasty (SLT), which incorporates a technique for the treatment of open angle glaucoma
SLT lowers intraocular pressure by using short pulses of an Nd:YAG laser to target melanin-containing cells in the trabecular meshwork, resulting in increased fluid outflow.
The limitations of argon laser trabeculoplasty (ALT) are primarily related to its coagulative effect, which leads to scarring of the trabecular meshwork. SLT retains the therapeutic benefit of laser treatment-reduced intraocular pressure, without the collateral thermal damage to non-melanin containing cells and to the trabecular meshwork structure.
First FDA approved SLT laser to ever enter the market
Stand alone and self-contained within its own slit lamp and table
