How Lasers are used in Modern Surgeries

LASER (Light Amplification by Stimulated Emission of Radiation) is a popular solution in the modern medical field. Light has varying wavelengths and spreads in all directions. With laser technology, the wavelength can be customized to match certain operations. Focusing it on a narrow beam creates a high-intensity light that’s used in varying surgeries. With the accurate focus on a specific spot, laser is used for precise surgical operations and cutting through tissue instead of the traditional scalpel. With a range of products from the Sentient Lasers collection, you can find a solution that best matches your practice. So how are lasers’ used in modern surgeries? Here is a quick look at the common applications.


Cancer is a significant menace in the healthcare industry. With a laser, the cells can be destroyed or shrink tumor for easier removal. The laser therapy approach focuses a beam of light, shrinking the cancer cells or destroying them. During surgery, the light can be used to cut out tumors. The process employs an intense, narrow beam that can accurately be focused to remove or destroy the abnormal cells. The precision ensures that other tissues around the tumor aren’t damaged. The process is more effective with a laser, keeping in mind that cells absorb light of varying wavelengths. As such, tumor cells can be precisely targeted by choosing a laser wavelength that won’t affect normal cells. It is easier to melt, destroy, or shrink the tumor with such a wavelength without exposing a patient to many risks.

Help in blood loss prevention

Blood loss is among the most challenging risks associated with surgeries. Laser coagulation is among the popular uses in operations, preventing blood loss. Coagulation or clotting the tissues with a laser involves visible, mostly green wavelength. The light is selectively absorbed by hemoglobin, sealing off bleeding blood vessels.

Eye surgery

Correcting or improving vision through surgery is among the most common applications propelling laser’s popularity in the medical field. Have you come across Lasik? It is an effective approach that’s favored over glasses or contact lens. Lasik (laser-assisted in situ keratomileusis) helps to change the shape of the cornea. The cornea is the clear dome-shaped tissue located at the front of an eye. Conditions such as far or nearsightedness and astigmatism affect how light is bent. This causes blurred vision. With Lasik surgery, the cornea is reshaped, altering light-bending ability and hence improved vision.

Dental procedures

Laser is used in varying dental procedures. This includes basic tooth whitening and complex surgeries such as reshaping the gums. Lesion and biopsy removal are among the significant uses that emphasize laser’s effectiveness in dental procedures. Lesion removal in the mouth relieves canker sore pain. Biopsy’s purpose is to get a piece of tissue for cancer examination.

While the use of laser in non-invasive operations such as in cosmetic surgeries has continued to propel its popularity, the technology’s contributions to more demanding surgical operations can’t be overlooked. The precision and versatility contributions make laser an excellent solution in the medical field, facilitating quality healthcare service delivery.
