Nearly two decades of myopia laser surgery has “blossomed”, the safety and effectiveness has been clear, the people often still ask, the long term will rebound? Here we will talk about the stability and precautions of myopia laser, especially the minimally invasive nature of the new laser surgery all-femtosecond SMILE. Myopia in China is a social issue of greater public concern. How can myopic patients get better results and mitigate risks from laser surgery? Pre-operative education is one of the keys. Pre-operative education for myopic patients should include understanding not only the principles and major modalities of myopic laser, but also recent trends, as well as perioperative precautions and medication care. The basic principle of myopic laser is to use a laser to polish the cornea, allowing the cornea to slightly change its refractive power, thus adjusting the focus of the eye and allowing myopic people to see distant objects clearly again. The latest all-femtosecond laser SMILE is a small incision corneal lens removal, minimally invasive, micro-edge cut only 2 mm, no excimer laser, better long-term stability, less reaction, the biggest advantage is the post-operative pain and other irritation response is light and short, effective vision recovery is fast, is the current 1000 degrees or less of myopia is one of the best adapted way, especially those intense sports, fight against rushing, etc. LASEK is also suitable for people with low myopia and relatively thin corneas under 200 degrees, due to its superficial cutting level, and is a surgery that does not require a “knife”. Not everyone can have the surgery, but it is usually required to be over 18 years old, relatively stable refractive error in the past two years, generally correctable myopia up to 1000 degrees, astigmatism up to 600 degrees, stop wearing soft contact lenses for more than 1 week, and all anterior and posterior segment examination data are qualified. 1000 degrees or more or even 2200 degrees of myopia, then ICL surgery is required, which is an intraocular lens implantation. Surgery is also stable and reliable when performed on a thorough evaluation. There are many items that should be understood and selected for a thorough examination at a regular eye clinic before deciding on surgery. Do not push the surgeon when discussing with him/her after receiving a thorough examination, for example, surgery is not possible in case of active inflammatory lesions in the eye. Without an adequate cognitive base and a good psychological and appropriate degree of expectation, those who rush to request surgery are prone to potential risks and hidden dangers. It is also important to know the eye protection and medication before and after surgery as well as the recovery process of surgery. After the surgery, it is important to pay attention to the use of artificial tears to alleviate the effects of dry eyes, and not to neglect the nourishment of the eyes by continuously surfing the Internet for too long without restraint. Myopic laser surgery may seem very quick, but it is not easy. In particular, the pre-operative examination and evaluation, the selection and design of the surgical plan, and the post-operative care and maintenance require the cooperation and awareness of the myopic patient. On the platform of friendly and adequate doctor-patient communication, perfect and reliable evaluation, scientific and reasonable design, perfect surgical operation, thorough follow-up and reasonable medication are the guarantee of high-quality surgery and the best visual quality. Femtosecond SMILE improves the quality of vision and thus the quality of life, but it is inseparable from health education, so that myopic patients are fully aware of the precautions, and the high technology can really bring them good vision.
