1. Can myopia be operated on? Myopia (including accompanying astigmatism and some farsightedness) can be operated on to achieve improved vision. Generally speaking, it can be considered in adulthood (18 years old), with relatively stable myopia and no contraindications after examination. However, it is important to understand that surgery is not a treatment for myopia, but a correction of vision. The myopic nature of the eye does not change after surgery, but the vision is improved, making life easier and vision clearer! 2.Who is suitable for myopia surgery and is there an age requirement? Indications: Patients who are unwilling or unable to wear glasses, patients who cannot tolerate contact lenses, patients with special occupational needs, patients who have no contraindications to surgery and meet the requirements for surgery can all be considered. The age of surgery is generally 18~55 years old, but for patients younger than 18 years old or older than 55 years old, it is not necessarily true, mainly because before 18 years old, the development of the eye has not yet stopped and the prescription is not yet stable, so it is not done, but for some patients such as severe refractive aberration, certain diseases need, cannot be fitted with glasses but need to improve vision, although the age is not yet, after a comprehensive assessment can be considered (such as hyperopic amblyopia patients, because the treatment should be early, can not be delayed, the age can be relaxed). Patients over 55 years old, on the other hand, mainly consider the possibility of cataracts, which may lead to vision loss and require cataract surgery to solve the problem. 3.What are the methods of myopia surgery and how to choose? At present, there are many surgical methods and types, and it should be said that most patients can find the most suitable method, mainly: Excimer laser surgery: it can be divided into LASIK, LASEK, femtosecond laser, etc. Generally, for myopia below 500 degrees, LASEK is the best choice (except for patients with scars), and LASIK is better for 600 to 1200 degrees (scar patients are generally not affected). ), but require normal corneal thickness, if the cornea is thin, or have corneal abnormalities, can choose crystal surgery. Crystal surgery: Patients with 1200~2000 degrees, or patients with thin corneas who wish to obtain the ideal result although the degree is not high, can choose crystal surgery for the best result. There are two types of crystals, anterior chamber and posterior chamber, and the posterior chamber is currently safer and more effective.
