Dacryocystorhinostomy (DCR) is a surgery conducted in the ophthalmology department.
It is needed in the case of a blocked tear duct, a condition known as nasolacrimal
duct obstruction (NDO).

Tears drainage can be blocked when the bone around the tear duct keeps, unnaturally,
growing, causing an infection or inflammation of the nasolacrimal sac.

The first recommended treatment for this condition is antibiotics; however, they
are not always effective, especially in the case of recurrent or severe infections.

In such cases, the obstructed lacrimal sac has to be opened. External surgery usually
results in an undesirable facial scar, in addition to the excessive bleeding during
and after the surgery. 

Therefore, intranasal surgeries, using Laser-assisted dacryocystorhinostomy (L-DCR),
are encouraged. L-DCR expands the narrowed or blocked duct by removing the bone 
that has caused the duct’s narrowing and facilitated the canal blockage.

surgical devices, particularly the [SIFLASER 3.3](https://sifsof.com/product/medical-diode-laser-systems-siflaser-3-3/)
and **[SIFLASER 3.2](https://sifsof.com/product/smart-medical-diode-laser-siflaser-3-2/)

have a wide range of wavelengths that varies between 455 nm and 1470 nm and a power
range of 0.5W – 60W, depending on the application of the product and adaptable to
the needs of the surgeon. Short wavelengths have more superficial penetration, while
longer wavelengths have deeper penetration in the tissue.

Diode laser is one of the common laser types used in DCR surgeries. The main advantages
of the diode-laser-system-based SIFLASER devices is that they result in no external
facial skin scars, surgery is possible with local anesthesia only, less bleeding,
a smooth and accurate bone cut in a fast procedure.
