Any surgery has certain risks and unpredictability. Although excimer laser surgery is very precise and safe, there is some damage to the corneal tissue. Refractive lens implantation surgery can correct very high levels of myopia, but after all, there are risks associated with implanting a lens into the eye. The safest method is to wear frames, although this is not the most convenient or comfortable method. Although the complication rate for refractive surgery is low, the risks listed on the surgical signature sheet are all possible. The purpose of the list is to give you a full picture of the surgery before you make the decision to undergo it. Before the surgery, you should think twice about how strong your desire is to have your glasses removed and whether you are mentally prepared to take the risks that may occur. Being prepared will help you to cooperate with the surgeon during the surgery. If you still have thought concerns before the surgery, please talk to the surgeon directly and do not go through the surgery with uneasiness and doubts. Generally, the surgery is not painful, but there will be a little discomfort. The surgeon will need the patient’s cooperation during the surgery, which includes two things: 1. Try to follow the surgeon’s instructions and look at the light above you (although it is very shaky). 2, do not squeeze the eyes, surgery must be both eyes open, so as to ensure that the eye position is correct, the laser hit the accurate. After the surgery, there will be a short-term foreign body sensation in the eye, slight stinging and tearing, do not rub your eyes, do not squeeze your eyes, this is very important, because squeezing your eyes may lead to the misalignment of the corneal flap, which will affect the effect of the surgery. It is difficult for physicians to give the best answer about which procedure is better. I personally think that if you have enough rest time, myopia is less than 500 degrees, choose epi-lasik,lasek is very good, that is, there is a certain amount of irritation for 2-3 days after the operation, the recovery of vision after the operation is a little slower, you have to come for review every month for the first six months, and you have to use the eye medication for about 4 months, but the long-term effect will be better. The side effect is that the eye medicine has a certain elevation effect on the eye pressure, to prevent the occurrence of glaucoma. In addition, through the examination, their own conditions are not very good, or even found some problems, the physician advised the patient to suspend or not laser surgery, but the patient does not understand, but also run around various hospitals to consult. In fact, from the physician’s point of view: the physician does not recommend surgery is certainly a certain reason, certainly from the patient’s point of view. Surgery time is very short, but the physician’s duty is to maximize the protection of the patient’s interests and safety. If the surgery may cause serious adverse consequences to the patient, that is to give how much money can not be done, because the patient is responsible for the rest of his life. Don’t be reluctant to undergo the surgery and look at the long term. Some patients who are not suitable for excimer laser surgery can also opt for other options such as refractive lens implantation. In addition, for ultra-high myopia, such as myopia of more than 1100 degrees, foreign countries are now gradually carrying out the implantation of IOLs. Although the surgery requires higher and more comprehensive requirements for the surgeon’s surgical techniques and clinical experience, the surgical effect is very good and does not damage the cornea. The whole procedure takes only 10-15 minutes per eye, with no pain and fast recovery. Although the cost is higher, at$10,000 for one eye, price is not the main deciding factor because, after all, people only have the opportunity to choose surgery once in their lives, and they hope to achieve good results after one surgery. If it is because of limited affordability, you can hold off on the surgery and choose the best method when you have enough financial resources. It is recommended that physicians in the country should introduce new treatments to these patients to give them one more option. If you decide to choose to undergo surgery, it is important to actively cooperate with the doctor’s requirements. Sometimes things happen during and after surgery that we cannot anticipate, and even experienced doctors may not be able to completely predict and avoid them. For example, a poorly made corneal flap during LASIK surgery occurs with an incomplete flap. If the surgeon empirically believes that the current situation is not suitable for continuing the surgery, based on long-term vision considerations, he or she may recommend stopping the surgery at this time, resetting the flap without surgery for the time being, and waiting for 2-3 months for another surgery, which would be more effective. It is in the patient’s best interest for the surgeon to make this decision, and the patient should cooperate with the surgeon and follow his or her instructions. Another example is that if the corneal flap is found to be poorly aligned in the post-operative review after LASIK surgery, and it is necessary to return to the operating room to re-lift the flap back into place, then the patient should actively cooperate with the doctor, or else a delay in treatment will lead to a poor long-term outcome. Both the surgeon and the patient start from the same place, hoping for an optimal outcome after surgery. However, differences in individual responses and mechanical unpredictability can lead to things that cannot be predicted preoperatively, and are not something that everyone’s subjective wishes may influence. Once that happens, the doctor will actively try to find a solution, and the patient should fully understand and cooperate with the doctor. Only mutual cooperation and trust between the doctor and the patient will be conducive to post-operative recovery. Regular review after surgery is also important. Especially for patients with high myopia, even though glasses are removed after surgery, relevant eye examinations should be conducted annually to avoid retinopathy associated with high myopia and so on.
