What you don't know about laser magic: How it can perfectly reshape vision in eye surgery?
Laser surgery is a form of surgery that uses a laser to cut tissue, unlike a traditional scalpel. With the advancement of technology, laser technology has become one of the most important tools in eye surgery. Especially in vision correction, the popularity and application of laser surgery has changed the lives of millions of people around the world. This article will delve into the working principle of laser surgery and its application in eye surgery, revealing the wonderful process of how this technology can reshape vision.
Basic principles of laser surgery
The core of laser operation lies in its precision and control. Different laser wavelengths and equipment settings will produce different effects on tissue. Taking eye surgery as an example, the types of lasers used include carbon dioxide laser, sapphire laser and excimer laser, each with different characteristics.
Advances in laser surgery technology allow doctors to precisely reshape the structure of the eye with virtually no bleeding.
Applications of eye laser surgery
In ophthalmology, laser surgery is mainly used for vision correction, especially the treatment of myopia and hyperopia. The most well-known procedures include LASIK and optical keratectomy (PRK). Not only are these surgeries effective at improving vision, they can also help patients become less dependent on glasses or contact lenses.
LASIK surgery
LASIK surgery combines blade and laser technology. First, the blade is used to cut out a flap of the cornea, and then the laser is used to reshape the lower layer of the cornea. This process improves the ability to focus light as it enters the eye.
Many patients who once relied on glasses enjoy clear vision after LASIK surgery, and their quality of life is significantly improved as a result.
Optical keratectomy (PRK)
PRK surgery removes the upper layer of corneal cells and adjusts them directly with laser. It is usually suitable for patients who are not suitable for LASIK surgery. Although the recovery time of this surgery is longer, the effect is equally remarkable.
The science and technology behind lasers
The optical principle of laser surgery is derived from "selective photothermolysis therapy". When a laser beam strikes tissue containing specific pigments, the tissue absorbs the laser light, generating heat, effectively destroying or removing unnecessary tissue. This principle applies not only to ophthalmology, but also to dermatology and other surgeries.
Advantages of laser surgery
The application of laser technology makes the surgical process safer and less invasive. Due to the precision of the laser, patients experience shorter recovery times after surgery and the risk of postoperative complications is reduced.
Looking ahead: The future of laser surgery
With the rapid advancement of laser technology, future eye surgeries will be more refined and personalized. For example, the recent ReLEx SMILE technology not only reduces intervention on the cornea, but also provides a more comfortable surgical experience.
With the further development of laser surgery, vision correction surgery will move towards higher precision and safety.
Conclusion
Laser magic not only reshapes our vision, but also changes the landscape of the medical industry, allowing countless people to see new hope and possibilities in life. However, regarding the future of this technology, we should also think about whether it can continue to lead the innovation direction of eye surgery?
