Many of my patients and colleagues often ask me, is it safe to have myopic surgery? Is it necessary to have myopic surgery? Why don’t doctors who perform excimer laser surgery do it themselves? Questions like these are asked every day. So, do you have the desire to remove your glasses? Are you still worried? What are your concerns? I would like to analyze this question from the following points. Refractive eye surgery for myopia is the icing on the cake, and is itself performed on relatively normal eyes, so safety is the main concern. Excimer laser is an ultraviolet light beam invisible to the human eye, which is a cold laser and produces no thermal effect on the irradiated tissue. Under computer control, it can precisely ablate the part of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues and organs. The excimer laser has a short wavelength that does not penetrate into the eye, making it a very stable and safe procedure. Of course, any surgery has risks, some of the complications that we are concerned about such as: 1, flap complications: LASIK surgery flap process, there may be formed incomplete flap, epithelial flap, thin flap and so on, but this kind of complication incidence is two out of a thousand, if the use of femtosecond technology to make flaps, can be reduced to a few out of 10,000, so it can be said that the rate of incidence is very small. Even if it occurs, it can be operated again after three months, which will not affect the surgical effect. 2, the occurrence of cone cornea. Conical cornea is a kind of congenital eye disease which has some relationship with heredity, and his seriousness is well known, the constantly bulging cornea makes the patient lose most of the vision, and ultimately can only rely on corneal transplantation to treat. It cannot be denied that excimer laser surgery has contributed to the occurrence and development of cone cornea. However, according to the literature, the natural incidence of cone cornea is 1 in 2,000, and up to 2004, the number of cone cornea cases after laser surgery reported in the English-speaking medical literature around the world was less than 100, while the number of cases that had undergone laser surgery was estimated to be more than 10 million worldwide. That is to say, the incidence of cone cornea after laser surgery is not higher than that without surgery. In this way we presume that anyone who develops the disease should be someone who has cone cornea potential themselves. Our current screening for cone cornea and the grasp of the scale of surgery is very careful, never because of medical factors that make a completely normal person into a cone cornea patients. 3. Retinal detachment occurs. Close screening before surgery, patients with retinal tears or degeneration early laser tear closure surgery, closed after the exact excimer laser surgery, as mentioned earlier cone cornea, LASIK will not increase the incidence of retinal detachment. Likewise, LASIK does not increase the incidence of retinal detachment. It also does not increase the difficulty of retinal detachment surgery. 4. Can I have cataract surgery when I am old? People’s concern about cataract surgery is mainly about the accuracy of the implanted IOL measurement. Now we can tell you clearly that the existing A ultrasound instrument can accurately measure the degree of IOL after excimer laser surgery, so there is no need to worry. Are you ready for myopic surgery? Firstly, you should be psychologically prepared . Learn about excimer laser surgery through various ways. Don’t be biased and don’t just focus on individual cases. Know your expectation of this surgery and know your psychological bottom line. Second, action preparation. Consult the professional doctor directly to answer the doubts in your mind from the perspective of the professional doctor. Undergo relevant pre-operative examinations to understand your specific situation. As for the question, “Why do doctors wear glasses when they don’t go for LASIK themselves?” This question is not really surprising. Just as the plastic surgeon does not always have to cut double eyelids, nose pads, breast augmentation, chin reduction, nut vendors do not eat three meals a day with fried chestnuts as a meal, demand is the first. Besides, as far as I know, it’s not uncommon for doctors who love beauty to do LASIK.
