Myopic laser surgery, or keratomileusis, is one of the more clinically established treatments to correct true myopia. Myopia is divided into pseudomyopia and true myopia. In the case of pseudomyopia, the main thing is to release the tension of the ciliary muscle, such as using ciliary muscle paralyzing drops, looking away, and reducing the time spent on each near eye, etc. No treatment is needed. In case of true myopia, the treatment options available are: wearing frame glasses, wearing corneal contact lenses, corneal refractive surgery (laser surgery) and intraocular refractive surgery, so having laser surgery is one of the common methods of treating myopia. Corneal refractive surgery is a surgical procedure to change the shape of the cornea in order to correct refractive errors and is indicated for myopic patients who do not want to or whose occupation does not allow optical correction (frames and contact lenses). There are strict indications: age 18-50 years old; stable refractive error for at least two years; preoperative examination indexes met; no other serious eye diseases (e.g., cone cornea, keratitis, glaucoma, etc.); no diabetes, collagen disease and scarring; good psychological quality and willingness to operate, etc. The recovery of vision after surgery is a gradual process and usually takes more than one month to achieve the best results of stability. Therefore, if myopic patients need it, “laser surgery” is an option.
