Five misunderstandings about myopia surgery

Abstract: laser surgery for myopia has a certain age limit. The age range of surgery was 18 to 55 years. For teenagers under the age of 18, their eyeballs are still in the development stage, the eye axis is still growing, and the degree of myopia is unstable. It is suggested that surgery should be carried out when the eyeball development and the degree of myopia are relatively stable., Conscription and examination of civil servants have certain vision requirements. Many people have completely got rid of myopia glasses through myopia surgery, but many myopia friends have stepped into a misunderstanding when considering myopia surgery. In the face of these problems, Professor He Zili, the chief excimer expert of Guigang aiyan hospital, answered the patients’ errors in their understanding of myopia surgery., Be careful not to enter the following misunderstanding in myopia surgery. Misunderstanding 1: laser surgery can be done at any age. Myopia laser surgery has a certain age limit. The age range of surgery was 18 to 55 years. For teenagers under the age of 18, their eyeballs are still in the development stage, the eye axis is still growing, and the degree of myopia is unstable. It is suggested that the operation should be carried out when the eyeball development and the degree of myopia are relatively stable. If the operation is performed rashly, the effect is poor and myopia is easy to occur again. In addition, myopia patients older than 55 years old are not suitable for laser surgery. Because after the age of 50, the incidence of cataract increases gradually, and the regulatory function of the eyeball decreases gradually, the commonly known “presbyopia” begins to increase. Therefore, it is not appropriate to perform myopia laser surgery at this time., Myth 2: no matter how thick the “wine bottle bottom” can be removed by laser surgery, myopia laser surgery is not “omnipotent”. In addition to age limits, there are also degree limits. In principle, the range of myopia laser surgery is 200 degrees to 1200 degrees. If myopia exceeds 1000 degrees, ICL lens implantation is recommended. For myopia patients with more than 1200 degrees, laser cutting will make the retained corneal tissue too thin, prone to lordosis under the action of intraocular pressure, and even secondary keratoconus in severe cases, which can be remedied only by corneal transplantation., Myth 3: laser surgery is not necessarily safe.

myopia surgery be careful not to enter the following misunderstanding

misunderstanding 1: laser surgery can be performed at any age. There is a certain age limit for

myopia laser surgery. The age range of surgery was 18 to 55 years. For teenagers under the age of 18, their eyeballs are still in the development stage, the eye axis is still growing, and the degree of myopia is unstable. It is suggested that the operation should be carried out when the eyeball development and the degree of myopia are relatively stable. If the operation is performed rashly, the effect is poor and myopia is easy to occur again. In addition, myopia patients older than 55 years old are not suitable for laser surgery. Because after the age of 50, the incidence of cataract increases gradually, and the regulatory function of the eyeball decreases gradually, the commonly known “presbyopia” begins to increase. Therefore, it is not appropriate to do myopia laser surgery at this time. Misunderstanding 2 of

and

: no matter how thick the “bottom of the wine bottle” is, laser surgery can be done to remove

and

myopia. Laser surgery is not “omnipotent”. In addition to age limits, there are also degree limits. In principle, the range of myopia laser surgery is 200 degrees to 1200 degrees. If myopia exceeds 1000 degrees, ICL lens implantation is recommended. For myopia patients with more than 1200 degrees, laser cutting will make the retained corneal tissue too thin, prone to lordosis under the action of intraocular pressure, and even secondary keratoconus, which can be remedied by corneal transplantation.

misunderstanding 3: laser surgery is not necessarily safe.

excimer laser surgery is used to correct myopia, astigmatism and other refractive errors. In fact, it uses high-efficiency light beam to cut the front surface of cornea, change the curvature of the front surface of cornea, adjust the refractive power of cornea, and make the external light accurately image on the retina, So as to achieve the effect of correction. Before excimer laser myopia surgery, doctors need to conduct more than a dozen detailed examinations on patients. According to the examination results, they carefully give a rigorous and scientific operation plan. Only by passing the rigorous preoperative examination, the safety of the operation is guaranteed. Tens of millions of people around the world have removed their myopia glasses through myopia surgery. Misunderstanding 4 of

and

: myopia will “rebound” after surgery. The acceleration of myopia usually occurs between the ages of 12 and 18, and most people will gradually stabilize after the age of 18. Myopia laser surgery is a very precise and strict operation, which is controlled by computer. A concave mirror is precisely cut out on the cornea, and the molecular bonds between corneal tissues are disconnected and gasified by cold laser. As long as you follow the doctor’s advice, pay attention to eye hygiene, maintain good eye habits, and avoid further lengthening of the eye axis, myopia will not rebound. Misunderstanding 5 of

and

: it can only treat myopia, but not astigmatism.

and

many myopia patients are accompanied by astigmatism, and the discomfort caused by astigmatism is often more serious than myopia. If it is not corrected, it will also cause amblyopia and visual fatigue. Many myopia patients worry that excimer laser surgery can only correct myopia. If astigmatism continues to exist, it will still lead to blurred vision and need to wear frame glasses. In fact, excimer laser corneal surgery also has certain advantages in the correction of astigmatism. Laser can not only cut concave lens on the cornea to treat myopia, but also make cylindrical lens and convex lens within 600 degrees on the cornea at the same time. Therefore, excimer laser corneal surgery can treat myopia from 200 degrees to 1200 degrees and astigmatism within 600 degrees at one time, as well as hyperopia within 600 degrees.
