Preface

“ In the past two weeks , Not only the number of outpatient services increased over the same period last year 10%, The number of operations has reached a peak of more than 100 a day .” Professor Yu Keming, Department of myopia laser therapy, Zhongshan Eye Center, Sun Yat sen University, pointed out in an interview , Especially with the college entrance examination results in Guangdong 、 Scores were announced one after another , Many graduates choose to fill in military colleges and universities , These units have requirements for naked eye vision , So ask to do “ Take off the mirror ” The number of young people undergoing surgery is about twice as many as usual .

Myopic surgery is not “ Come and do it ”, It is “ Let's check first ”

Yu Keming introduced , At present, the mainstream myopia surgery mainly includes corneal refractive surgery and intraocular refractive surgery . The former includes excimer laser surgery （LASIK、LASEK、PRK）、 Half a femtosecond （FS-LASIK） And full femtosecond （SMILE） Laser surgery , The latter with ICL Lens implantation surgery is the main .

“ Can you do myopia correction surgery , What kind of surgical method is suitable , Mainly based on preoperative examination . Must pass including naked eye vision 、 Vision with glasses 、 Intraocular pressure 、 Axis of the eye 、 Corneal thickness, etc 20 Multiple checks , There can be no less .” Yu Keming said , I often meet patients who are anxious to take off the mirror , But myopic surgery is not a simple commodity , You can do it when you come , It's a medical act , Risk awareness must be maintained .

“ Such as keratoconus patients , Because its corneal thickness and biomechanical strength are not enough , After full femtosecond corneal ablation , It will make the original disease worse .” Yu Keming introduced , Except keratoconus , Glaucoma 、 Patients with retinal detachment and other systemic diseases , All need to consider whether to perform surgery , And choose the operation time carefully . And even without the above diseases , It also depends on the thickness of the cornea , Generally speaking , The degree of myopia exceeds 1000 Degree patients , It may not be suitable to use corneal refractive surgery to solve the problem of myopia , We can consider the surgical method of lens implantation .

Parents often make several mistakes in matching glasses

“ The child's eyes are not mature and the degree is unstable in the juvenile stage , Unless there are special pathological reasons , Myopic surgery is generally not recommended , Matching glasses is relatively the mainstream .” Associate Professor Yang Jing of the Department of refraction of the hospital said , Summer vacation is coming , This period in previous years is also the upsurge of primary and secondary school matching , Some mistakes related to matching glasses need to be pointed out .

“ Parents often fall into these problems ： First, if your eyesight decreases, you should immediately buy your child myopia glasses to wear ; Second, do not dilate pupils in professional medical institutions before matching glasses .” Yang Jing pointed out , When teenagers have decreased vision , Considering that there may also be complications caused by other diseases , Therefore, we must first go to a regular hospital for systematic examination , Don't easily characterize as myopia or even worry about buying myopia glasses . Yang Jing also said , Mydriasis is not only safe , It can also diagnose the type of ametropia （ Namely myopia 、 hyperopia 、 astigmatism ） And get accurate diopter , Only in this way can we judge the true and false myopia and then consider whether we need glasses . But after mydriasis, there will be fear of light 、 Blurred vision and other symptoms , It will take some time to fully recover , In order not to delay normal study and life , It is suggested to go to a professional medical institution for mydriatic optometry during the holiday .

“ Besides , Many parents and friends ask the doctor to give a standard answer , It seems that only tell them 50 Degree or 100 You have to wear glasses , They can feel at ease . In fact, when children wear glasses and their eye needs 、 Whether it affects life, etc , Please be sure to use glasses reasonably under the guidance of a doctor .” Yang Jing said .
