1. Make patient supine.
2. Anesthesia. Across retrobulbar anesthesia.
3. Place the laser fiber in contact with the first central government after the corneosclera
margin of 1.5 ~ 2mm department. 
4. Make the G-probe directed towards the ciliary body crown. Laser energy use is 1.5-2w, time 0.5-1s, 24-34 hit spots, each spot between the internal of 1.5-2.0mm
5. Initial power setting is 1.5w and then adjust the power with 0.1w steplength until hear the “popping” sound. Using this power finish the treatment.
6. After the treatment, partial adrenal cortex hormones and antibiotics given to drug points, eyes, and symptomatic use IOP lowering drugs. Oral pain medications when necessary.

Advantage:
1. More safe and effective. The 810nm diode laser for the near-infrared light, the penetrating strong selectively absorbed by pigmented ciliary body, destruction ciliary epithelial cells, so that a decrease in aqueous secretion to reduce intraocular pressure.
2. Not only can effectively relieve pain, but also to reduce the intraocular pressure to a lower level and protection of remaining visual function.
3. No serious complications after surgery, when the intraocular pressure increased again, it can repeat the treatment. The interval of treatments is better more than 1 month.
4. Simple and low price.

Notice:
1. Avoid excessive photocoagulation
2. 3 and 9 o’clock positions were spared to avoid the long ciliary nerves during the treatments
3. DLTSCPC surgery on the ciliary body injury is a non-reversible damage, so we are now only used in the clinical phase of the late and absolute glaucoma with poor visual function.

Nasolacrimal Duct Obstruction (NLDO)


Nasolacrimal duct obstruction (NLDO) is a fairly common disorder clinically manifested by the presence of tearing, purulent discharge, and  less often, associated  with sterile or 
infected dacryocystitis. Although medical treatment including antibiotic therapy may address temporary relieve of the symptoms, most authors believe that surgical 
intervention is the choice of  management for primary or secondary nasolacrimal duct obstruction in which   patency of the lacrimal outflow system is restored. 

Related Key-words:
DCR,endonasal,laser,lacrimal sac.

Medical device:
 CHEESE 10W 980nm (1-10w continue.300J)

Accessories:
ENT handpiece,endoscopy

Operation procedure:   
1.General anethesia or sedation underwent nasal mucosal shrinkage and predisposing factors for NLDO 
2.Conect the fiber to the handpiece ,then connect to the device and test the laser if work normally.
3.Endocanalicular illuminating fiber or use the red pilot beam of the laser fiber helped in exact pin-pointing the lowermost part of the sac.
4.Through the handpiece into the canaliculus with harm to the lumen,burn the anterior attachments of the middle turbinate and lacrimal bone for 30 seconds to make a 1*1cm bony opening.Energy estimayed to be at least 300 joules.

Advantage:
In contrast to intra nasal drilling for bone removal, use of 
the laser is very simple and easier to usege

Notice:
1. Alaser fiber was then easily passed through one canaliculus to reach the medial wall of the sac. Intra nasal saline irrigation was used to 
    prevent thermal damage to the adjacent tissues.
2 A silicone tube was passed through the canaliculi in all the external and endonasal patients and kept in place at least  for three months
3.In both groups identical topical antibiotics and steroid drops were prescribed for one week. In cases of nasal anatomical correction, packing was removed on the third post operation day
4.Weekly office visits for one month and monthly inspection continued for three months when the tube was removed and the canaliculo-nasal fistula was irrigated.
5.Follow-up were scheduled three-monthly for nine further months with irrigation test carried out in each visit

Medical device:
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.
