Seven key factors determining the quality of myopia surgery

Abstract: the purpose of preoperative examination of myopia is to confirm whether it can be operated, eliminate potential keratoconus and severe dry eyes, And thin cornea (relative myopia degree) and other surgical contraindications; then provide accurate surgical data, such as corneal curvature, degree, astigmatism axis, corneal topographic map or wavefront aberration. From the development process and trend of corneal refractive surgery, it can be seen that the safety and effect of modern myopia surgery are beyond doubt, and with the further development of technology and equipment, myopia surgery will More perfect. But even with the most advanced surgical methods, we must pay strict attention to every detail of the operation to ensure the accuracy of the operation. After all, myopia surgery is carried out in “healthy eyes”, and no “carelessness” is allowed. The following is my summary of the more important factors that determine the quality of surgery., I. preoperative examination.

from the development process and trend of corneal refractive surgery, it can be seen that the safety and effect of modern myopia surgery are beyond doubt, and with the further development of technology and equipment, myopia surgery will become more perfect. But even with the most advanced surgical methods, we must pay strict attention to every detail of the operation to ensure the accuracy of the operation. After all, myopia surgery is carried out in “healthy eyes”, and no “carelessness” is allowed. The following is my summary of the more important factors that determine the quality of surgery.

I. preoperative examination the purpose of

preoperative examination is to confirm whether the operation can be performed, eliminate potential keratoconus and seriously dry eyes, And thin cornea (relative myopia degree) and other surgical contraindications; then provide accurate surgical data, such as corneal curvature, degree, astigmatism axis, corneal topographic map or wavefront aberration; in addition, professional preoperative examination can also screen other eye diseases, especially fundus diseases, such as fundus hemorrhage, retinal hole and detachment. In short, perfect preoperative examination is to ensure the safety and effectiveness of surgery The premise of fruit.

2. Preoperative evaluation and scheme design

preoperative evaluation should comprehensively consider the actual needs of patients, myopia, psychology and many other aspects. If the expectation of surgery is too high, surgery is not recommended even if the eye conditions are suitable for surgery. The actual needs of each patient may be different, and the specific eye conditions are also different. Personalized consideration must be given in the surgical design, so as to achieve the best effect for each individual.

III The diagnosis and treatment equipment

and

laser surgery is in the cornea (i.e. black eyes) are treated by laser cutting, while the central thickness of human cornea is only about 0.5mm, which requires that any link before and during the operation must be accurate and safe, and must reach the micron level during surgical treatment. At the same time, the operation also needs an advanced real-time tracking system to ensure that accurate data can be accurately “copied” to the patient’s cornea.

IV. the

laser surgical equipment in the laminar flow operating room are high-precision equipment, and the indoor constant temperature, humidity and pressure can ensure the stable performance of the laser equipment. This requires that the excimer operating room must be a laminar flow operating room, and the air purification degree is generally required to reach 10000 level standard (≥ 0.5 per cubic foot of air) μ M ≤ 10000 particles or ≤ 350 particles per liter of air). At the same time, laminar flow operating room can effectively control the incidence of infection and interlayer reaction.

v. postoperative review

the stable period of myopia surgery is generally half a year to one year after operation. Therefore, regular follow-up should be carried out during this period. It should be emphasized that the changes that patients can intuitively feel are mainly visual acuity. In most cases, visual acuity changes are after the changes of diopter, intraocular pressure and corneal thickness, and the early changes are easier to be controlled by drugs. Therefore, with timely follow-up, the doctor can timely adjust the medication and treatment plan according to the specific situation, so as to make the recipient spend the relatively unstable period smoothly, so as to achieve the best long-term effect.

VI. communication and service

good communication and service can not only make patients have reasonable postoperative expectations, but also relieve patients’ tension. We should not only make the patients clearly understand the possible situations during and after the operation, but also make the patients feel that the operation should experience a “pain”. Patients have a peaceful state of mind, so they can better cooperate with doctors before and during operation. This is a crucial decisive factor in the modern myopia operation system.

and

VII. Although examination and operation doctors

and

are the last point, doctors are the most important link in the whole treatment process, because the above six points need to be completed by relevant doctors. No matter how precise the instrument is, no matter how advanced the technology is, people are ultimately required to operate and implement it. But we should also realize that modern myopia surgery has become more and more intelligent and “fool”, the important role and experience of doctors
