The history and trends of corneal refractive surgery show that the safety and effectiveness of modern myopia surgery is beyond doubt and will become even more perfect with further development of techniques and equipment. However, even with the most advanced surgical procedures, we must pay strict attention to every detail of the surgery to ensure its accuracy. After all, myopia surgery is performed on a “healthy eye” and does not allow for the slightest “sloppiness”. The following is a summary of the more important factors that determine the quality of surgery. Pre-operative examination The purpose of pre-operative examination is firstly to confirm whether surgery is possible and to exclude contraindications such as potential cone cornea, severe dry eye, and corneal thinness (relative myopia); then to provide accurate surgical data, such as corneal curvature, degree, axial astigmatism, corneal topography or wavefront aberration; furthermore, professional pre-operative examination can also screen for other eye diseases, especially fundus diseases, such as fundus hemorrhage, retinal fissure and detachment. Retinal fissures and detachments, etc. In short, perfect preoperative examination is a prerequisite to ensure the safety and effect of surgery. Pre-operative evaluation and program design The pre-operative evaluation should take into account the patient’s actual needs, myopia, psychological and other aspects. If the expectation of surgery is too high, even if the eye condition is suitable for surgery, it is not recommended. The actual needs of each patient may be different, and the specific conditions of the eye may be different, so individualized consideration must be given to the surgical design in order to achieve the best results for each individual. Laser surgery is performed on the cornea (i.e., the black eye) to treat myopia, and the central thickness of the cornea in the human eye is only about 0.5mm, which requires precision and safety in any part of the pre-operative and intra-operative process, and must reach the micron level during the surgical treatment. At the same time, the surgery also requires an advanced real-time tracking system to ensure that the precise data can be accurately “copied” to the patient’s cornea. Four, laminar flow operating room laser surgery equipment are high-precision equipment, indoor constant temperature, humidity, constant pressure to ensure the stability of laser equipment performance. This requires that the laminar operating room must be a laminar flow operating room, which generally requires the air purification degree to reach 10000 level (≤10,000 dust particles ≥0.5μm per cubic foot of air or ≤350 particles per liter of air). At the same time, laminar flow operating rooms can also effectively control the incidence of infection and interlaminar reaction. V. Postoperative review The stabilization period of myopia surgery is usually after six months to one year after surgery, therefore, regular follow-up visits should be made in all this time period. It should be emphasized that the changes that patients can feel visually are mainly visual acuity, while in most cases, visual acuity changes after changes in refractive error, intraocular pressure, corneal thickness, etc., and early changes are more easily controlled by medication. Therefore, with timely follow-up, the doctor can adjust the medication and treatment plan according to the specific situation, so that the patient can smoothly pass the relatively unstable period and thus achieve the best long-term results. Sixth, communication and service Good communication and service not only can make patients have reasonable postoperative expectations, but also, most importantly, can relieve patients’ tension. It is necessary to let patients clearly understand the possible situation during and after surgery, and not to make them feel that they have to go through a “painful” operation. Patients with a calm state of mind can better cooperate with the surgeon before and during surgery, which is a crucial decisive factor in the modern myopia surgery system. Although it is placed at the last point, the physician is the most important part of the whole treatment process, because all the above six points need to be completed by the relevant physician. More sophisticated instruments, more advanced technology, ultimately need people to operate and implement. But we should also recognize that modern myopia surgery has become increasingly intelligent, and the important role and experience of the physician is no longer to complete a beautiful surgery, but to be able to perfectly handle the various complex individual differences and ensure the safety and effectiveness of the surgery. If the eye hospital you want to visit can do the above seven points to perfection, then all you have to do is to enjoy the pleasure of clear vision!
