Abstract: Although corneal refractive surgery has been carried out in China for many years, many people are still in a wait-and-see attitude and worry about some negative effects after surgery. Is this myopia correction really safe? Will it increase the risk of some eye diseases?, In recent years, the incidence rate of juvenile myopia has ranked the highest in the world and has a trend towards younger age and higher number. According to statistics, the average myopia rate of teenagers in China has reached 40%, and among high school students and college students, this proportion has far exceeded 70%, and has increased year by year. Sun ran, an ophthalmologist at Xuanwu Hospital, pointed out that the harm caused by adolescent myopia not only affects the study, life and physical and mental health of teenagers, but also causes various ophthalmic complications. Therefore, it is particularly important to prevent and correct juvenile myopia in the early stage., Although corneal refractive surgery has been carried out in China for many years, many people are still in a wait-and-see attitude, worried about some negative effects after surgery.

Recently, at the “establishment meeting of myopia correction surgery professional clinic of Xuanwu Hospital”, ophthalmologists corrected the name of myopia correction surgery, saying that the mainstream myopia correction surgery currently carried out is very safe.

surgery is not recommended for severe dry eye.
recently, at the “establishment meeting of myopia correction surgery professional outpatient department of Xuanwu Hospital”, ophthalmologists corrected the name of myopia correction surgery, saying that the mainstream myopia correction surgery currently carried out is very safe, and there is no clear statistics to show that the glaucoma The prevalence of eye diseases such as cataract will increase.

Sun ran introduced that corneal refractive surgery is to correct the cornea with cold laser irradiation. Patients who are willing to undergo surgery can go to the professional outpatient department of myopia surgery for consultation according to their own needs.

myopia surgery is not once and for all. Patients need to follow the doctor’s advice and have regular follow-up visits. Because surgery can not prevent the development of myopia, we should pay attention to eye hygiene, prevent fatigue, eye use and nutritional intake after surgery, so as to protect and maintain stability of vision.
hot spot explanation
won’t cause fundus lesions such as glaucoma
Q: will corneal refractive surgery cause eye lesions?
and
Sun ran: this kind of operation is an eye surface operation and does not affect the intraocular structure. Therefore, it will not lead to fundus diseases such as glaucoma and cataract. However, hormone eye drops need to be used after operation to inhibit corneal scar and epithelial hyperplasia. If hormone eye drops are used for more than two weeks, it may increase the intraocular pressure and have the possibility of glaucoma, but if they are stopped, the intraocular pressure will decrease. At present, femtosecond laser and combined excimer laser are most commonly used in corneal refractive surgery. The use time of hormone eye drops after this operation is generally only 10-12 days, and the risk of glaucoma is very low. At present, the history of this operation has been 30 years, and the first batch of correctors are very old. There is no clear statistics to show that the incidence of glaucoma and cataract will increase after operation. The incidence rate of keratoconus is also lower than incidence rate of general population.
rebound is related to personal eye habits
Q: will there be rebound after operation?
Sun ran: there is a possibility of rebound, which is still related to personal eye habits. After operation, we must pay attention to eye hygiene and avoid fatigue. If it is high myopia and unstable within two years, it will rebound after operation, so a detailed eye examination should be carried out before operation. The first examination takes about two hours to ask about the history of relevant diseases, and the diopter should be checked the next day. If there is a rebound of 100-200 degrees, the corrector of half femtosecond laser surgery can be used to make up the play. The number of times depends on the film thickness, and some people can make up the playTwo or three times, but the degree is generally stable after making up one time.
