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.

What should I do if nearsightedness is inherited by my child?

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 myopia correction rebound?

Will there be a rebound after myopia correction surgery? Generally, it relates to two aspects. The first is associated with your pre-surgery degree of myopia; the second relates to your habits in using your eyes after the surgery. Generally speaking, the higher the degree of myopia before the surgery, the more likely a rebound will occur. Roughly speaking, if your degree of myopia was above 700 degrees before the surgery, there's about a 20% to 30% chance of rebounding. However, a rebound does not mean it will return to the previous degree of over 700; typically, it might rebound by around 100 to 200 degrees. The second aspect is significantly related to your post-surgery visual habits. If, after the surgery, you frequently use computers, read documents, or use your phone, there’s a higher chance of experiencing some degree of rebound. Conversely, if your screen time is less, the proportion of myopia rebound tends to be smaller.

Can high myopia with bulging eyes be corrected?

High myopia with bulging eyes is caused by the elongation of the eye axis, which is irreversible. Myopia is when parallel light rays entering the eye are focused in front of the retina, after passing through the eye's refractive system, and thus cannot form a clear image on the retina. Myopia can be classified into low, moderate, and high degrees, with high myopia defined as 600 degrees or more. Once myopia progresses to true myopia, it is incurable, and one can only correct or control its progression. Before the age of 18, myopia can only be corrected and controlled by wearing frame glasses or orthokeratology lenses; after the age of 18, elective surgeries like myopic correction surgery or artificial lens implantation are also available options for correcting 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.

Is a child's vision of 4.7 considered nearsighted?

Children's vision at 4.7 does require a comprehensive analysis to determine if they are nearsighted. Generally, a child with a vision of 4.7 is likely to be nearsighted, but this single parameter should not be used to diagnose myopia. It's necessary to differentiate whether the child has true myopia or false myopia. Additionally, the issue could be amblyopia, astigmatism, or farsightedness. Moreover, the child's age also plays a significant role in assessing vision. For instance, a vision of 4.7 might indicate nearsightedness in a child aged seven or eight, but for a child around three years old, a vision of 4.7 is considered normal. Parents are advised to take their child to the hospital for a dilated refraction test to ascertain the specific condition.
