With the development of the economy and the improvement of people’s material living conditions, more and more myopic patients want to remove their glasses. The treatment of refractive error is a complex medical problem. According to survey data, the incidence of myopia in our population is 33%, and the number of myopic eyes in the country is nearly 400 million, which is one of the countries with the highest incidence of myopia in the world. Myopia has become an important problem that affects the health of our people. Since the 1970s, ophthalmologists in various countries have shown a keen interest in this issue. In the late 1980s, excimer laser surgery was introduced, which opened a new era of refractive eye surgery by virtue of high technology and in-depth research on the etiology of myopia and animal experiments. Because the results of excimer laser correction for high, medium and low myopia were far superior to those of previous refractive surgery, it soon caught the attention of ophthalmologists worldwide. Excimer laser technology has been used for more than 20 years and has proven to be safe and reliable. The three main types of excimer laser refractive surgery that are widely performed are PRK, LASEK and LASIK, and the indications for the three types of surgery to correct myopia vary. It is up to the patient to make a prudent choice based on a full understanding of their situation. In recent years, with the continuous improvement of excimer laser equipment, the accuracy, predictability, safety and reliability of myopia surgery has been improving. Currently, LASIK (excimer laser in situ keratomileusis) is internationally recognized as the safest, most mature and effective refractive surgery. Compared to the other two procedures, LASIK has a wide range of indications and this method is available to 99% of patients. The principle is to use a microkeratome to form a corneal flap, and then use a laser to cut the corneal stroma under the flap. After cutting, the cut flap is restored to its original position; the curvature of the cornea is reduced after cutting, and the refractive power of the cornea is reduced, thus correcting myopia. LASIK has been widely used in China because of its wide range of application, preservation of the integrity of the corneal epithelium and anterior elastic layer, more consistent with the anatomical and physiological structure of the cornea, rapid recovery from postoperative pain relief, and short medication time. However, it requires a higher level of skill than the previous PRK and LASEK surgeries. Therefore, reputable hospitals and experienced doctors are more willing to choose LASIK to increase the safety of patients, and this surgery is favored by patients. The key factor in choosing myopia surgery is the qualification of the hospital and its own indications, do not choose surgery blindly, not that the more expensive surgery, the more advanced technology is better, must listen to the advice of professional doctors, only the right surgery to achieve the best results. It is understood that myopia correction surgery has strict indications and contraindications. For example, the age of 18 years or older; refractive error stability for about 2 years: no cone cornea, viral keratitis, glaucoma, dry eye and other serious eye disease; no diabetes, collagen disease and scarring, etc.; should also have a good psychological quality. It should be noted that some of the contraindications to surgery are not absolute, and some cases can be operated on with caution under proper management and close observation, but only after both the surgeon and the patient have weighed the pros and cons. Patients need to undergo preoperative examinations of visual acuity, refraction, fundus (pupil dilation), intraocular pressure, as well as medical optometry, corneal topography, corneal thickness measurement, slit lamp examination and other corresponding examinations necessary for surgery. Director Zhou Yuehua emphasized that laser surgery only corrects the refractive error, while other eye pathologies associated with the original myopia still occur. Therefore, post-surgery patients are still more prone to myopia-induced fundus complications (such as fundus hemorrhage and retinal detachment) than normal people, and if left untreated, they may also be at risk of blindness, but this situation is not clearly related to the surgery itself. Any surgery has its risks. Choosing a regular hospital is a prerequisite for safety Excimer laser keratomileusis is an effective method of correcting refractive errors, but surgery can only help you remove your glasses, not change the nature of your myopia. The results of the surgery are related to the surgeon’s skill and the quality of the equipment, but also to the patient’s own condition, the degree of refractive error and its stability, the ability of the wound to heal, and the intraoperative cooperation. The excimer laser used for myopia correction is a high-tech device that is upgraded and updated very quickly. Whether a patient is suitable for excimer laser surgery and what type of surgery to choose must be decided by a professional ophthalmologist after a detailed examination at a regular professional hospital. Therefore, I hope that the majority of myopic patients will not be deceived by some false advertising, do not be greedy for cheap, must be careful to choose professional regular hospital consultation and treatment, so as not to cause lifelong regrets. Last tip: “Medicine is an evolving science, a risky business that cannot be perfect and always has regrets. Therefore, even if the best doctor puts all his efforts into his patients, he cannot make every patient completely satisfied. Because the success of any surgery has more or less known and unknown correlations with the development of medicine, the doctor’s technique, the characteristics of the condition itself, the patient’s own cooperation and his or her own factors, we will constantly strive to improve our technique, and at the same time, we hope that every patient who is ready for surgery will carefully weigh the risks of the surgery and his or her own needs for removal of glasses, and choose the surgery carefully. “
