Laser myopia surgery has been developed for more than 20 years, and its advantages and disadvantages have been discussed in many research papers. In fact, no operation can be absolutely 100% safe and satisfactory. Therefore, patients must have a clear understanding of the operation, reasonable expectations, and a sense of risk-taking.

The most important premise is that not all myopic people can receive laser myopia surgery. In addition to being at least 18 years old, with stable myopia and no pregnancy, if you have keratoconus (referring to the thinning and protruding cornea of the eye and In severe cases, cornea transplantation is required), hidden keratoconus (check with corneal mapper, anterior chamber analyzer, etc.), dry eye, history of autoimmune and connective tissue diseases, severe dryness Syndrome, end-stage glaucoma, severe diabetes, etc., are not suitable for surgery. If there is a retinal hole or detachment, it needs to be treated first. The Japanese Academy of Ophthalmology proposed guidelines for surgery in 2008, recommending surgery within 6D. 6D~10D may be due to the high degree of myopia. Although such treatment can be provided, it is necessary to pay attention to whether the thickness of the cornea is sufficient. Implantable intraocular lenses are acceptable.

LASIK myopia laser surgery, which was approved by the US Food and Drug Administration (FDA) in 2016, uses lasers to change the curvature of the cornea to improve vision. Although myopia laser surgery in recent years focuses on painless and quick recovery, experts warn that LASIK laser surgery is still risky, and its sequelae include symptoms such as dry eye, light sensitivity, blurred vision, and various astigmatism. Usually these symptoms are short-lived, but there is the possibility of permanent damage such as blindness, pain and interference with daily life.

At the same time, laser surgery is not suitable for everyone. In the case of LASIK, those who have refitted glasses and contact lenses within a year, have a history of diabetes, and take drugs that will affect wound healing, or have glaucoma, herpes, etc. Eye diseases such as infection or eye inflammation, and people who have had eye injuries or surgery are not suitable. At the same time, people who are prone to dry eyes, large pupils, and thin corneas should also think twice.

After laser surgery, it is also possible to become short-sighted again. After corneal thinning, the cornea with the original concave lens may be affected due to the increase of intraocular pressure and the return of short-sightedness. This part can be performed LASIK again, but it will not be recommended if the cornea is too thin or in poor condition.

After Lasik surgery in the United StatescomplicationPatient voluntary organization, publicizing the risks of Lasik. They also build websites, some of the better known arewww.lifeafterLasik.comand Lasik Complications (www.Lasikcomplications.com), to provide medical and even legal help and guidance for those who have undergone Lasik surgery.
