Lasik surgery is safe and reliable, and has been recognized and accepted by a large number of myopic patients. It is a relatively mature and effective method for correcting myopia, hyperopia, and astigmatism in adults, and is now very popular. Tens of millions of people around the world have already undergone this surgery. Many myopic patients hope to get rid of their glasses through this surgery and enjoy a clear and free field of vision. However, due to a lack of basic understanding of this surgery among many patients, there are many misconceptions that cause great psychological pressure on the treatment of myopia.
Concern one: If the surgery fails, it will damage the eyes, causing injury or even blindness. Equipment technology principle ensures no failure: In fact, excimer laser is ultraviolet light with a very short wavelength (193 nanometers). This surgery is highly automated and computer-controlled, providing high safety.
Concern two: Over time, the effect will rebound, making the cost not worthwhile. Biological principles indicate that myopia will not recur after surgery: To explain the principle of excimer laser surgery in less technical terms, it's like creating a personalized biological glasses on your corneal stroma using modern molecular lasers. The amazing laser prevents the flattened part of the front of the eyeball from regenerating and becoming convex again, so the therapeutic effect is quite stable. If the degree of myopia before treatment has been stable in recent years and the front-to-back diameter of the eyeball does not elongate anymore, then myopia will not reappear after treatment.
Concern three: Since it is surgery, it involves cutting, which brings great pain. Surgical principles show no pain; there is no sensation or pain during laser treatment. After the surgery, you can go home immediately without needing to stay in the hospital. Normal eye use is not affected, just like cataract surgery.
