Not all myopia is hereditary, but high myopia does have a genetic component. The occurrence of myopia is mainly related to genetic and environmental factors. If there are children in the family with a history of high myopia, they should develop good eye habits from a young age, or undergo genetic testing for high myopia. If myopia occurs, it can be corrected by wearing glasses, or by refractive surgery after reaching adulthood.

Does nearsightedness surgery require hospitalization?

Myopia surgery does not require hospitalization; it is completed on an outpatient basis. Before the surgery, routine blood tests, screenings for infectious diseases, and specialized eye examinations are conducted. If the pre-operative examinations are thorough and there are no contraindications for surgery, the procedure can be performed on an outpatient basis. After the surgery, patients can go home and must return to the surgical hospital the next day for a follow-up examination. Post-operative medication should be used as prescribed by the surgeon, and regular follow-up appointments should be scheduled.

Is 1000-degree acquired myopia hereditary?

High myopia of 1000 degrees can also be inherited. The inheritance of myopia is mainly significant in cases of high myopia. If both parents have high myopia, the heritability is almost above 90%. If one parent has high myopia, the heritability is 45%. If neither parent is myopic, the heritability is nearly 5%. Myopia is primarily formed due to improper use of eyes rather than hereditary factors, which are relatively rare and generally only account for about 10% of myopia cases. Therefore, correct use of eyes is very important.

Children's myopia lacks which trace elements?

The relationship between myopia in children and the lack of trace elements is not significant. Myopia is generally caused by several reasons: The first is hereditary factors, where one or both parents may have myopia. The second reason is poor eye habits in children, such as sitting too close to the desk while doing homework, or excessive use of the eyes, like watching TV or spending a long time on mobile phones, which can easily lead to myopia in children. Once a child develops myopia, the degree could increase by 50-100 degrees each year. Thus, if this is the case, it is necessary to conduct a timely dilated optometry for the child to confirm whether they can wear orthokeratology lenses. If the child is over eight years old and all conditions are suitable, orthokeratology lenses can be prescribed to control the progression of myopia.

The difference between amblyopia and myopia.

Amblyopia refers to a condition where, through examination, the eyeball has no organic lesions, but the vision is poor. Even after correction, the vision remains significantly lower than normal, generally less than or equal to 0.8, without any organic lesions in the eyeball. In such cases, amblyopia can be considered. Myopia, on the other hand, refers to poor vision that can reach normal or better levels after correction. The difference between the two is that amblyopia cannot be fully corrected through adjustment, whereas myopia can be completely corrected. In terms of treatment, myopia can be corrected by wearing glasses or undergoing surgery, while amblyopia can only be managed by wearing glasses or undergoing specific amblyopia treatments.

Will nearsightedness be inherited?

Myopia has a certain hereditary aspect, but it is mainly caused by improper use of the eyes. Myopia is characterized by clear near vision and blurred distant vision, primarily due to changes in the eye's axial length. After the onset of myopia, it is crucial to properly dilate the pupils and conduct an optometric examination to rule out false myopia and amblyopia. Currently, the main treatments for myopia are still corrective glasses or orthokeratology lenses. Surgical treatment can also be considered for individuals aged 20 to 45. Once myopia develops, proper eye usage should be practiced, reducing close-range activities to avoid eye strain, and regular follow-ups are advised.
