Myopia is not only a refractive problem, but a series of complications arising from myopia can lead to more serious conditions, especially pathological myopia, which is actually an eye syndrome. Myopic patients are not only affected by their education and career choices, but also their life, work and sports. It is the common wish of myopic patients to get rid of their glasses and regain clear and free vision, however, people are always worried about the safety of the surgery. How to improve the safety of the surgery? How can the safety of the surgery be improved and the postoperative results be guaranteed? Over the years, excimer laser surgery and inspection equipment have been constantly updated, and inspections have become more and more precise, resulting in an unprecedented peak in both equipment and technology. The safety and effectiveness of the procedure are becoming more and more recognized and respected as the number of people undergoing the procedure continues to increase. Of particular interest is the fact that since the introduction of the excimer laser, there has not been a single case of blindness worldwide as a result. The post-operative satisfaction rate is also very high. Due to the lack of basic understanding of this procedure, many patients have misconceptions, which are explained below. The fear of injury or even blindness indicates that the patient lacks basic knowledge about the excimer laser. Excimer laser is a very short wavelength (193 nm) ultraviolet light, it is a kind of light wave that can be precisely focused and controlled, with a very high precision, each pulse cutting depth accuracy of 0.2 um, it can carve all kinds of patterns on the human hair, it is cutting at the molecular level, extremely precise, so it is impossible to penetrate the eye. And it is a cold light source that does not produce heat damage, and by this accurate vaporization, it can precisely vaporize one tenth of the corneal layer without producing adverse effects on the structure of the cornea. Some people also worry about hurting other parts of the eye, which is also much worry, because excimer laser machines are equipped with infrared tracking system, when your eye deflects beyond the normal range, the laser will automatically stop shooting, to ensure safe treatment. Myth 2: It will slowly bounce back over time, and it’s not worth the money? To explain the excimer laser principle in less esoteric terms, the modern molecular laser is used to create your own pair of biological glasses on the stroma of your cornea. Since this part of the tissue does not regenerate, the restored vision is clear and stable, thus effectively solving the trouble of wearing glasses. Money has a price, clear, sharp, wide and free vision is priceless. Myth 3: Since it is a surgery, it will be open and bring great pain? The whole procedure takes about ten minutes, and the laser scanning process takes only twenty to thirty seconds. There is no pain, you can go home after the surgery, no hospitalization is required, and most of them can achieve a vision of more than 1.0 the day after the surgery, which does not affect normal life and work. Myth #4: Is this surgery available for all myopic eyes? No, it is not. The entire pre-operative examination takes 2 hours, and you will go through a total of 19 precise examinations. If you successfully pass the pre-operative examination, you can undergo the surgery with peace of mind. We strictly screen out every special case that is not suitable for surgery, such as thin cornea, cone cornea, fundus lesion, etc., so that safety will be carried out to the end! Misconception 5: It is a minor surgery, many hospitals can perform it? Excimer laser is not an ordinary minor surgery. The health supervision department has a strict accreditation system for hospital admissions, and physicians must have strict training by the Ministry of Health and be certified with equipment and have a senior title to carry out surgery. The surgical equipment introduced must be brand new and certified by the national health department. The surgical environment cannot be less than 25 square meters and must have laminar flow purification equipment to maintain a sterile environment. In addition, there are strict requirements for pre-operative examination equipment, related staffing, surgical process management and all other aspects. Myth 6: Poor long-term results after myopia surgery? Or will myopia surgery leave sequelae in old age? To clearly analyze this issue, we must start with the principle of laser treatment for myopia. Myopia is caused by the front and back diameter of the eye being too long, or the front surface of the cornea being too convex, so that the external parallel light entering the eye is focused at a point in front of the retina and cannot accurately converge at the base of the eye. Excimer laser treatment for myopia uses a computer to precisely control the beam of the excimer laser to flatten the front surface of the cornea and reduce the curvature of the central area of the cornea so that the focal point of myopia can be shifted back and accurately converge into a clear image on the retina to achieve the purpose of myopia correction. The laser only cuts 10-15% of the corneal thickness during the treatment process, and this part of the tissue will not be regenerated for life, therefore, no change will occur in old age, it is stable and will not have any effect on other tissues of the eye. Therefore, I always emphasize one point to my patients before surgery: “Once a person is over 45 years old, at most 50 years old, whether you have received myopia surgery or not, you will need a pair of glasses to help you see far or near, and it is almost impossible to completely get rid of For those with less than 300 degrees of myopia, you will still need to put on your current glasses to see far away and remove them to see close up. For those with more than 300 degrees of moderate to high myopia, they also need to wear the same number of glasses to see far away, and after taking off the glasses to see near, they still need to wear a pair of glasses 200 degrees lower than the glasses to see the computer, books, cell phones and other close targets, that is, they need to wear two pairs of glasses to see far and near. In conclusion, excimer laser myopia surgery has been tested for 20 years and more than 10 million people worldwide have successfully undergone laser myopia surgery. Our hospital has also been performing the procedure for ten years and has successfully treated nearly 10,000 cases without any serious accidents and has an excellent reputation. The FDA, the most stringent regulatory body in the United States, also passed and approved molecular laser correction for myopia, hyperopia and astigmatism as a safe and effective method as early as 1995 after a long and rigorous review. Of course, any surgery has some risks, there are risks need to consider the probability of occurrence, from clinical experience and the design of the principle of surgery, its safety is very high, and the emergence of complications are generally within the acceptable range. If you choose a treatment center with experienced doctors and strict quality control, you can reduce the possible risks to a minimum. And a recent research study by the Australian Centre for Vision Research noted that patients’ subjective well-being, resilience and confidence increased significantly after undergoing excimer laser surgery, thus improving not only their naked eye vision, but more importantly, their quality of life.
