Laser medicine

Laser medicine is a branch of medicine that utilizes lasers for the diagnosis, treatment, and management of various medical conditions. This technology harnesses focused light energy to achieve various therapeutic effects, providing a range of applications across multiple medical specialties.

Dental lasers are specialized devices that use focused light energy to perform various dental procedures. They emit a concentrated beam of light, which can be absorbed by different tissues in the mouth, such as gums and teeth, depending on the wavelength of the laser. This technology is utilized for a range of applications in dentistry due to its precision, effectiveness, and minimally invasive nature.

LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a popular surgical procedure used to correct refractive vision problems, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The main goal of LASIK is to reduce a person's dependence on glasses or contact lenses. During the LASIK procedure, a surgeon uses a specialized laser to reshape the cornea—the clear front part of the eye.

Blood irradiation therapy, often referred to as photopheresis or extracorporeal photopheresis (ECP), is a medical treatment used primarily for certain hematologic conditions, including cutaneous T-cell lymphoma (CTCL) and graft-versus-host disease (GVHD). The therapy involves the collection of a patient's blood, which is then treated with a photosensitizing agent, most commonly 8-methoxypsoralen (8-MOP).

Computed Tomography Laser Mammography (CTLM) is a medical imaging technique that uses laser technology to create detailed images of breast tissue. It is primarily designed to provide an alternative or complementary method for detecting breast cancer and assessing breast health, particularly in women with dense breast tissue where traditional mammography might be less effective. Key features of Computed Tomography Laser Mammography include: 1. **Laser Technology**: CTLM uses laser light to illuminate the breast tissue.

Cyclodestruction refers to a surgical procedure or treatment that involves the destruction of the ciliary body in the eye, which is responsible for producing the aqueous humor (the fluid in the eye). This procedure is primarily used to lower intraocular pressure in conditions such as glaucoma, where elevated pressure can lead to damage to the optic nerve and vision loss. There are several techniques for performing cyclodestruction, including laser treatments (such as cyclophotocoagulation) and non-laser methods.

Endovenous laser treatment (EVLT) is a minimally invasive procedure used to treat varicose veins and venous insufficiency. It employs laser energy to close off or seal the affected veins, thereby redirecting blood flow to healthier veins. ### How the Procedure Works: 1. **Consultation and Diagnosis**: Before the procedure, a healthcare provider will usually perform a physical examination and possibly an ultrasound to assess the veins and determine the extent of the condition.

Laser ablation is a process in which material is removed from a solid (or occasionally liquid) surface by irradiation with a laser beam. The laser energy is focused onto the material, causing it to heat and vaporize, or to be ejected in particles or as a plume of vapor. This technique is widely used in various fields, including materials science, surface engineering, and medical applications.

Laser blended vision is a vision correction technique that combines elements of both LASIK (Laser-Assisted In Situ Keratomileusis) and other refractive surgeries to address presbyopia and other age-related vision issues. It aims to provide a more natural range of vision for individuals who need correction for near and distance vision, often associated with aging. In the procedure, one eye may be corrected for distance vision, while the other is adjusted for near vision.

Laser coagulation is a medical procedure that utilizes focused laser energy to promote coagulation (clotting) of blood or tissues. This technique is commonly used in various medical fields, including ophthalmology, dermatology, and vascular surgery, to treat a variety of conditions. In ophthalmology, for example, laser coagulation is often employed to treat retinal conditions such as diabetic retinopathy, retinal tears, and age-related macular degeneration.

Laser hair removal is a medical procedure that uses concentrated beams of light (lasers) to remove unwanted hair from various parts of the body. The laser emits a specific wavelength of light that is absorbed by the pigment (melanin) in the hair follicles. This heat damages the follicles, inhibiting or delaying future hair growth.

Laser lithotripsy is a medical procedure used to break up kidney stones or urinary tract stones using a laser. The technique is generally performed during a procedure called ureteroscopy, where a thin, flexible tube (ureteroscope) is inserted into the urethra, through the bladder, and into the ureter or kidney. Here's how the procedure works: 1. **Preparation**: The patient is usually given anesthesia and positioned comfortably.

Laser surgery is a medical procedure that uses focused light energy (lasers) to perform various types of surgical interventions. The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation," and lasers can produce highly concentrated beams of light that can cut, cauterize, vaporize, or remove tissue with precision.

Low-level laser therapy (LLLT), also known as cold laser therapy or low-level light therapy (LLLT), is a non-invasive treatment that uses low-power lasers or light-emitting diodes (LEDs) to stimulate healing processes in tissues. It is primarily used for pain management, tissue repair, and inflammation reduction.

Mode locking is a technique used in lasers to generate short pulses of light (typically in the picosecond to femtosecond range) by forcing different longitudinal modes of the laser cavity to oscillate in phase. In a typical laser, multiple longitudinal modes (which are different frequencies of light that can oscillate in the cavity) can be present, but they may not be in sync with each other. This lack of synchronization results in a continuous wave output.
