What should I pay attention to?

When it comes to myopia and hyperopia, everyone almost knows, but when it comes to refractiveness, many people don’t know much about it. In fact, refractiveness does not mean that when the eye does not use regulation, the parallel light cannot form a clear image on the retina after the refractive effect of the eye, but in front or rear imaging of the retina. astigmatism.

Symptoms of refractiveness: The vision of remote eyes is determined by the high and low level of refractiveness and the strength of the regulatory force. Mild vision can be overcome with a small part of the regulatory force. Both and myopia can be normal. Generally, there are no symptoms. Such hyperopia is called hidden consequences. Those with low symptoms of refractiveness may have no manifestations, and slightly higher astigmatism can have vision loss. It is unclear to see far and near. It seems to have heavy shadows, and often has symptoms of vision fatigue. The slight hyperopia or regulatory force is slightly insufficient, so far and myopia is not good. The remaining parts of these cannot be fully adjusted are called explicit hyperopia, and the general consequences of hidden vision and vision are collectively referred to as chronological hyperopia. Because of the long -term adjustment of tension, it is prone to symptoms of vision fatigue. Clinical manifestations of myopia: Mild or moderate myopia, except for the ambiguity of the vision, do not have other symptoms. When working at close range, you can see the small goals without adjusting or using less adjustment, but it is convenient. However, at high myopia, the target distance is very close at work, and the two eyes are too much to gather inward, which will cause excessive use of the internal rectus and the symptoms of vision fatigue.

What should I pay attention to reflection? Eyes are a very precise and complicated optical organs in the human body. Glasses are products that protect the eyes, corrected vision, and have medical properties. According to ophthalmology experts, the eyes are protecting the eyes and correction of the refractiveness of the eyes.


Patients with refractiveness hope that they can take off their glasses as soon as possible, but not all patients with refractives can perform surgical treatment. The surgeon must strictly grasp the indication of refractive corneal surgery.

What should patients pay attention to refractive patients? Experts said that the surgeon should be over 18 years old and under 60 years old, because eyes under 18 years of age are still in the development stage, and the refractiveness will change; At the same time, the refractiveness is correct with artificial crystals. The number of refractives is stable for more than 2 years, and try to exclude myopia. Correcting the vision of 0.8 or more; no other eye disease and ophthalmology history, physical and mental health; no systemic disease that affects wound healing; patients voluntarily accept and can cooperate with treatment.

Before surgery, we should also conduct thorough examinations such as routine ophthalmological examinations, database optometry, corneal topographic diagram, corneal thickness examination, and subjective optometry. Those who wear corneal contact mirrors need to be removed for more than 2 weeks before checking. If you have decided to perform alphabet surgery, you should clearly tell the advantages and disadvantages of various surgery and possible complications of the recipients. Patients should also think twice.
