Corneal plastic lens PK laser myopia surgery, how much do you know?

Abstract: corneal shaping lens can help patients obtain ideal naked vision after wearing it at night and taking it out in the morning. This process will not change the corneal tissue structure and physiological characteristics of patients, but only shape the anterior surface of cornea.

corneal plastic lens is a physical treatment method for myopia, which is increasingly popular among teenagers and children in recent years. Today, with the continuous exposure of the disadvantages of laser myopia surgery and the high attention of the society, more and more myopia patients turn their eyes to corneal plastic lenses. So what is the difference between the two? What are the advantages of these myopia patients after all?

first of all, corneal shaping glasses can help patients obtain ideal naked vision after wearing them at night and taking them in the morning. This process will not change the corneal tissue structure and physiological characteristics of patients, but only shape the anterior surface of cornea. Therefore, the correction effect is reversible. Laser myopia surgery is different from keratoplasty. This operation will change the corneal tissue structure, which is likely to cause irreversible damage.

secondly, in terms of effect, adhering to the correct use of corneal shaping lens for a long time can effectively delay the deepening of myopia, which can not be achieved by laser myopia surgery.

again, in terms of applicable population, corneal plastic lens is also quite different from laser myopia surgery. Corneal shaping lens is suitable for people aged 6 to 40, especially for young children with myopia. Laser myopia surgery can only be used among adult patients with stable myopia.

finally, from a long-term perspective, patients who use corneal plastic lenses can change the lenses according to the changes of their refractive state, so as to obtain a more ideal correction effect. However, laser myopia surgery has no such convenience. If the refractive state of myopic patients changes, they can only adapt to surgery again. The problem is that the thickness of the cut cornea has decreased. Whether it supports another operation is still unknown.
