VELAS 980nm 30watt
Power setting:
10 Watt,
Ton 90ms(Pulse length),
Toff 50ms (Pulse interval)
Accessories:
600um bare fiber
Introduction and Operation procedure:
The main technical obstacles in laser assisted DCR are to deliver a sufficiently powerful laser beam via a relatively narrow optical fiber, which in turn fits into an endo canalicular probe.
We will use 980nm diode laser in repetitive mode, Power 10Watt, Ton (Pulse length) 90ms, Toff (Pulse interval) 50ms.
Osteotomy was achieved by applying laser energy via an optic fiber, which we inserted into the lacrimal sac with a probe. Irrigation with 0.9% saline solution of the endocanalicular probe was used to prevent overheating of the probe. The size of osteotomy was controlled through the nasal endoscope. Once an opening of at least 5 mm in diameter has been achieved, application of laser energy ceased.
Advantage:
1 Laser assisted DCR is a minimally invasive surgical procedure. It goes to the operating field through lacrimal canaliculus. It will minimize trauma to surrounding tissue and avoid unnecessary surgical skin scars.
2 Totally no bleeding through laser surgery
3 Short operation time and quick recovery for patients.
Notices:
1 Should find and examine lacrimal sac with a nasal endoscope.
2 Should pay attention to laser emission on surrounding tissues.
