Where Is Laser Therapy Applied?
How Do Laser Beams Work?
The practical information provided in this article about laser therapy will be very useful for you. The electrons of the atoms that make up an element rotate in a specific orbit. When these atoms are stimulated by external energy, heat, light, or electricity, the electrons change their orbits and become unstable. When the atoms are stimulated, the electrons return to their old stable states. During the transition from the unstable to the stable state, the atoms emit a higher energy beam than the beams that stimulated it. This newly created high-energy beam is called a laser. Laser beams create their effects by vibrating the molecules in tissues with the high energy they contain. The power produced in the tissue is directly proportional to the energy of the laser beams and inversely proportional to the diameter of the beam.
Treatments Using Carbon Dioxide Laser
Another factor determining the effect of these beams is the transmission of laser beams from the tissue. For example, the energy of the carbon dioxide laser is strongly absorbed by the water present in the tissues. Since most tissues are composed of water, the carbon dioxide laser begins to lose energy immediately upon contact with the tissue and can only penetrate to a depth of 0.1 mm. For this reason, the carbon dioxide laser is used to cut or burn surface tissue. Carbon dioxide laser is generally used in dermatology for the treatment of skin lesions. In contrast, the neodymium-YAG laser produces a much deeper effect on the tissue. The reason is that the tissue has a higher permeability to the neodymium-YAG laser. The neodymium-YAG laser, whose energy is not absorbed by water or blood, reaches a depth of 5 mm in the tissues. This type of laser, which can be easily passed through fiber optic devices, can be used in endoscopic, i.e., closed surgeries. Tissues in hard-to-reach areas can be cut or burned with laser beams sent into the body by endoscopic devices. Neodymium-YAG, holmium, and KTP potassium titanyl phosphate lasers are used to remove tumors in the body, repair vascular lesions, and treat prostate enlargement.
Eye Diseases Treated with Laser
The fluid produced behind the iris passes in front of the eye, lens, and the colored part of the iris and is absorbed by a band-like formation at the edges. Iris. Normally, the production and outflow of this fluid are balanced, and the intraocular pressure is within a narrow range. If there is a blockage in the area where the eye fluid is reabsorbed, the fluid begins to accumulate in the eye, and the intraocular pressure increases. Increased intraocular pressure can impair vision and even lead to blindness. Argon, krypton, or neodymium-YAG lasers are applied to the blocked area, allowing small holes to be opened for fluid reabsorption. One of the biggest long-term risks of diabetes is vision loss. Diabetes, which causes the vascular walls of the retina, the back layer of the eye, to weaken progressively, can even lead to blindness. When the vascular wall weakens, its permeability increases. Blood and serum passing from the vessels to the retina slowly cause a decrease in the field of vision. The argon laser is used to treat this condition, called diabetic retinopathy. The argon laser, which produces beams in the wavelength of blue and green light, reaches the blood vessels of the retina without damaging or absorbing the intraocular fluid. With the argon laser, the leaking is prevented by burning the weakened area of the vessel wall.
