Abstract: complications during operation: most of them are poor corneal flap cutting, such as incomplete or uneven cutting; As long as the corneal flap is restored, it can be operated again after three months., Myopia is an eye disease. However, now people have a wrong idea that they are short-sighted anyway and can recover their eyesight through myopia surgery. As everyone knows, myopia surgery also has sequelae, not 100% without side effects., The possible sequelae after myopia surgery are as follows: 1. Poor epidermal healing: it is more common in PRK. Therapeutic contact lenses and artificial tears can be used to help recover., 2. Invasion of impurities or epidermis under the corneal flap: slight ones do not affect vision, and serious ones must be removed by opening the corneal flap., 3. Surgery can not guarantee that the vision must reach 1.0. Some cases may have to operate again or wear glasses to get the best vision., 4. Infection: the wound is infected by bacteria due to operation or uncleanness after operation, and the probability is very low. As long as it is found early, most of them can be controlled by drugs., 5. Photophobia: the sensitivity to light increases within 3 to 6 months after operation, but most of them will gradually disappear after 6 months, and few cases will continue., 6. Corneal flap fold or displacement: it is only found in LASIK, which may be caused by trauma, resulting in irregular astigmatism and affecting vision. It can be operated again.,
myopia is an ophthalmic disease. However, now people have a wrong idea that they are short-sighted anyway and can recover their eyesight through myopia surgery. As everyone knows, myopia surgery also has sequelae, not 100% without side effects.
sequelae may appear after myopia surgery as follows:
1. Poor epidermal healing: it is more common in PRK, and therapeutic contact lenses and artificial tears can be used to help recover.
2. Impurities or epidermal invasion under the corneal flap: slight ones do not affect vision, and serious ones must be removed by opening the corneal flap.
3. Surgery can not guarantee that the visual acuity must reach 1.0. Some cases may have to operate again or wear glasses to get the best visual acuity.
4. Infection: the wound is infected by bacteria due to operation or uncleanness after operation. The probability is very low. As long as it is found early, most can be controlled by drugs.
5. Photophobia: the sensitivity to light increases within 3 to 6 months after operation, but most of them will gradually disappear after 6 months, and few cases will continue.
6. Corneal flap fold or displacement: it is only seen in LASIK. It may be caused by trauma, which will cause irregular astigmatism and affect vision. It can be operated again.
7. Glare or diplopia: it is common in the early stage of surgery, especially when the pupil becomes larger at night, most of them will disappear slowly, and only a few will continue.
8. Dry eye: tear secretion will decrease after laser surgery, which may produce dry eye symptoms or aggravate the symptoms of people with dry eyes. Artificial tear treatment must be supplemented, which can be improved in about 3-6 months.
9. Complications during operation: most of them are poor corneal flap cutting, such as incomplete or uneven cutting; As long as the corneal flap is restored, it can be operated again after three months.
10. Insufficient or excessive correction: myopia remains after operation, or hyperopia becomes beyond the expected correction degree, which is the most common side effect. Laser correction can be performed again after the degree is stable, depending on the situation.
11. Corneal opacity: it only occurs after PRK, which is positively correlated with the higher personal physique and correction degree. It is most obvious 1-3 months after operation. It must be controlled by steroid eye drops, and most of them will fade away slowly later.
12. Presbyopia: people close to or over the age of 40 may have presbyopia. After myopia correction, they do not need to wear glasses even if they look far away, but they still need to wear glasses when looking near or reading.
