After 20 years of development, excimer laser surgery has become by far the most effective way to fundamentally correct vision in the world. As myopic patients do not have enough detailed knowledge about the surgery, it is very easy to choose the wrong surgery. Opinion 1: To see more comfortably after surgery, “space eye” is more ideal Just like a person’s fingerprint, each person’s eye condition is unique. Therefore, myopia surgery needs to be “tailor-made”. The personalized myopia surgery, derived from space telescope technology and known as “space eye,” features iris recognition and wavefront phase contrast guidance technology, which draws a unique image of the eye under the control of a computer throughout the process, and performs precise laser treatment based on the image, improving the accuracy and safety of the surgery. Personalized surgery can effectively improve patients’ night vision, prevent post-operative glare, and enable clearer and more comfortable viewing. Personalized surgery is a good value for myopic patients who often drive at night. Opinion 2: The following groups of people, do not risk surgery Although excimer laser surgery has entered the era of high safety, not every myopic patient can receive excimer laser surgery. Those who are at least 18 years old, have stable myopia for the past two years, have no more than 1400 degrees of myopia, no more than 600 degrees of astigmatism, and no more than 600 degrees of hyperopia can undergo surgery only if they meet the above conditions. In addition, those who have eye inflammation, cone cornea, glaucoma, cataract, fundus disease or systemic connective tissue disease and autoimmune disease, severe scar body, pregnant women, and those who have big concerns about surgery are not suitable for excimer laser surgery. Opinion 3: Nearsightedness surgery cannot be done “on the go” Excimer laser surgery is short and does not require hospitalization, and vision can be restored to normal the next day, but it is not “on the go”. The principle of excimer laser surgery is that the excimer laser interacts photochemically with the cornea of the eye, cutting certain corneal tissue and changing the refractive power of the cornea for the purpose of treating myopia. The surgical procedure and the thickness of the cornea cut depend on a strict preoperative examination. Therefore, a rigorous and scientific 14-pass preoperative examination is essential, as well as a preoperative dilated eye examination and a second day of re-pupil examination. Patients preparing for excimer laser surgery must be examined at the hospital at least one day in advance. In addition, contact lens wearers should stop wearing them for at least 2 weeks before surgery. Opinion 4: The price of laser surgery varies, but the key is safety and results How much does excimer laser surgery cost? This is a concern for every myopia patient. The same kind of myopia surgery is available at various excimer laser centers at different prices. According to the regulations, “one person, one blade” must be implemented during the excimer laser surgery. The “blade” used to make the flap during surgery is costly, and if the blade is used repeatedly, it will reduce costs, but may result in uneven corneal cutting or errors, and may cause infection.
