Laser therapy uses focused light to perform medical treatments. Lasers allow for highly precise surgery by damaging only a small targeted area, resulting in less pain, swelling, and scarring for patients compared to traditional surgery. Laser therapy can be used to seal blood vessels during surgery, treat early-stage cancers, remove tumors or kidney stones, treat hair loss and remove things like warts or tattoos. While laser therapy provides benefits like precision and shorter recovery time, there are also risks like bleeding, infection, and pain, and treatments may need to be repeated.

2. What is LASER?
• A laser is a device that emits light through a process
of optical amplification based on simulated
emission of electromagnetic radiation.
• The word “laser” is an acronym for “ Light
Amplification by Simulated Emission of Radiation.
• Unlike most light sources, light from a laser is tuned
to specific wavelengths. This allows it to be focused
into powerful beams. Laser light is so intense that it
can be used to shape diamond, cut steel or even
cavity preparations in teeth.
• The first laser was built by Theodore H. Maiman at
Hughes Research Laboratories.

3. What is Laser Therapy?
• Laser therapy are medical treatments that use
focused light.
• In medicine, lasers allow surgeons to work at high
levels of precision by focusing on a small are,
damaging less of the surrounding tissue.
• Patients undergoing laser therapy experience less
pain, swelling and scarring than traditional surgery.

4. Uses of Laser Therapy
• Lasers can have a cauterizing, or sealing effect and may be used to
seal:
 nerve endings to reduce pain after surgery
Blood vessels to help prevent blood loss
Lymph vessels to reduce swelling and limit the spread of tumour cells.
• Lasers may be useful in treating the very early stages of some cancers,
such as cervical cancer, penile cancer, vaginal cancer, basal cell skin
cancer, etc. Also helps in relieving symptoms of cancers.
• Lasers can be used to shrink or destroy tumours, polyps or
precancerous growth.
• To remove kidney stones.
• Treat hair loss.

5. • Laser therapy can also be used
cosmetically for:
 To remove warts, moles,
birthmarks and sun spots.
To remove hair
Lessen the appearance of wrinkles,
blemishes or scars
Remove tattoos.
• Refractive eye surgery ( LASIK).
• Teeth whitening.

6. Contraindications
• Some laser surgeries, such as cosmetic skin and eye surgeries, are
considered elective surgeries. Some people decide the potential risks
can outweigh the benefits of these types of surgeries, like certain skin
conditions may be aggravated by laser surgeries.
• Poor overall health also increases your risk of complications.

7. What are the risks?
• Laser therapy has some risks such as:
Bleeding
Infection
Pain
Scarring
Changes in skin color
• Intended effect of treatment may not be permanent so repeated
sessions may be necessary.
• Some laser surgery is performed while the patient is under general
anesthesia. Which carries its own sett of risks such as:
Pneumonia
Confusion after waking from the operation
Heart attack
stroke

9. Benefits
• Lasers are more precise than traditional surgical instruments, and
cuts can be made shorter and shallower hence causes less damage to
tissue.
• Laser operations are usually shorter than traditional surgeries. They
can often be done on outpatient basis.
• Healing is faster with laser operations. Patient usually experiences
less pain, swelling and scarring than traditional surgeries.

10. Disadvantages
• It is costly for the patient and clinician.
• Increases intricacy and repetition of the treatment.
• It can cause harm to adjacent structures.
