The choice and design of myopia surgery methods need to be comprehensively considered based on factors such as the patient's preoperative examination results and postoperative vision requirements. Generally, patients can choose laser myopia surgery. If high visual acuity is needed due to study or work, or if there is high physical activity after surgery, it is recommended to choose a safer surgical option. This is because minimally invasive technology causes less trauma to the corneal nerves, which can more effectively improve postoperative night vision, greatly enhance visual quality, and better stabilize postoperative vision.

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.

What lenses should be used for nearsightedness?

Myopia, or nearsightedness, refers to a refractive condition where, in a relaxed state of accommodation, parallel light rays are focused in front of the retina after passing through the eye's refractive system. Myopia is categorized by degree into mild myopia, which is less than or equal to 300 degrees, moderate myopia ranging from 325 to 600 degrees, and high myopia, which is over 600 degrees. Generally, the degree of myopia is within 600 degrees, and most patients do not exhibit any pathological changes in the fundus. They require the use of suitable concave lenses for correction. If the degree of myopia exceeds 600 degrees, a fundus examination is necessary. If there are no special changes in the fundus, correction can also be made using appropriate concave lenses.

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.

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.

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.
