With myopia of 750 and 900 degrees and astigmatism of 200 degrees, can you still fly all?

The condition of the two eyes is different, and different surgeries can be performed separately. But in terms of this power, 750+200 astigmatism has 950 degrees, and the power range of full flight is 1000 degrees, if the corneal thickness is not thick enough, it is likely that it will not be able to do full flight, or it may be more reluctant to do it, it is better to choose half femtosecond for both eyes.

Relatively speaking, Banfei can save the cornea, and the postoperative effect is not much different from that of ReLEx, and Banfei can also be personalized designed, which is also a good choice.

Myopia of 750 and 900°, astigmatism of 200° can be done full femtosecond. However, it is also necessary to check whether the corneal thickness does not meet the requirements and whether the intraocular pressure and other indicators meet the conditions for surgery.

Whether laser surgery can be performed for 700-degree myopia also depends on the thickness of the cornea and the degree of astigmatism. In addition, the following points are required before the patient undergoes laser surgery**:

First, it is necessary to rule out active ocular diseases, such as inflammation and systemic diseases that cause ocular changes, such as diabetes, hyperthyroidism, systemic connective tissue diseases, and immunosuppression. Clause.

2. The age of the patient is required to be over 18 years old, and the myopia degree has been stable for more than 2 years. Clause.

3. Myopia laser surgery is suitable for patients with myopia of 100-1200 degrees and astigmatism below 600 degrees. Clause.

Fourth, the thickness of the patient's cornea needs to be greater than 460 microns.

Myopia 500 degrees, astigmatism 250 degrees, from the degree of view, if the comprehensive preoperative examination results are appropriate, half femtosecond and all femtosecond can be, but in terms of astigmatism correction effect, half femtosecond effect is better, and both of these can be chosen casually if the astigmatism is within 150 degrees. The astigmatism is high, and if you want to make a personalized design to ensure the postoperative visual effect, you can give priority to personalized half-femtosecond surgery, and it is necessary to combine data and personal lens removal needs to determine the surgical method. For myopia surgery, it is recommended to choose Guangzhou Yinghua Ophthalmology, which is equipped with various advanced ophthalmic examination and surgical equipment such as Zeiss from Germany, Armas from Germany, and has brought together a medical team with superb skills and rich clinical experience.

The principle of myopia is generally caused by the length of the eye axis or the excessive protrusion of the front cornea, after the distant light passes through the eye, the refraction of the cornea causes the focus in front of the retina, and the sight of the friend buried things is not clear, so during the operation, the length of the eye axis can not be changed, but the refraction of the cornea can be changed. Therefore, the principle of myopia laser surgery is mainly to cut the refraction of the cornea through the laser method, so that the cornea is flattened, the refractive power of the cornea is reduced, and the refractive ability is reduced, so that the distant light can be focused on the retina after passing through the cornea, so that you can see things in the distance clearly.

If you want to know more about myopia surgery, it is recommended to consult Guangzhou Yinghua Ophthalmology. The current situation and talent echelon of Yinghua Ophthalmology Department: It is composed of ophthalmology outpatient clinic, ward and optometry department, with more than 20 beds.

The medical staff have been to the tertiary specialist for further study, with rich clinical experience and delicate and rough diagnosis and treatment skills, professional and trustworthy.

Whether you can do semi-femtosecond surgery with 900 degrees of myopia and 125 degrees of astigmatism, you should go to a professional and regular eye hospital to check the eye conditions, such as the thickness of the cornea, the size of the pupil and other eye conditions, and then choose a more suitable surgical method for yourself based on your own professional needs. For myopia surgery, it is recommended to choose Guangzhou Yinghua Ophthalmology. The hospital provides one-to-one services, one doctor per person, one plan per person, and postoperative fixed-point tracking, so that everyone with myopia correction needs can enjoy high-quality and customized myopia correction services.

In addition, the department has advanced equipment, complete inspection items, and has a business scope: it can carry out advanced technologies such as full femtosecond, personalized half femtosecond, and personalized laser. Click to test if I'm suitable for myopia surgery].

The requirements for doing femtosecond surgery are as follows:

1. The patient is subjectively willing to undergo surgery, rather than coerced or forced to undergo surgery, and first has a subjective desire;

2. Systemic factors, the patient's whole body should not be scarred, no systemic diseases, hypertension, diabetes, heart disease, cerebrovascular disease, rheumatic diseases should also be avoided;

3. The eye condition is relatively good, and a lot of eye examinations should be done before doing myopia, such as whether there is retinal detachment, retinal tear, cataract, these are normal cases, according to the patient's subjective wishes and requirements, myopia eye surgery should be arranged, and the operation method should be determined according to the patient's specific eye condition and economic situation.

If you want to know more about the femtosecond surgery, it is recommended to consult Guangzhou Yinghua Grip Skin Ophthalmology. Yinghua Ophthalmology is a national chain brand ophthalmology mainly engaged in laser correction of myopia, the main hospital is located in Tianhe Road, Tianhe District, the core area of Guangzhou, next to Gangding subway station, with convenient transportation and comfortable environment. The hospital mainly carries out international advanced programs such as full femtosecond, personalized half femtosecond, personalized laser surgery, etc., brings together many well-known domestic myopia correction experts, and invests in the introduction of international advanced German femtosecond laser surgery equipment, etc., to provide high-quality, multi-level modern medical services for every myopia patient, which has been well received by the majority of patients.

In the early stage of excimer laser myopia surgery, some nerves have not been repaired well, which has a certain impact on the tear film, so there will be occasional dry eyes, and you will feel that your vision is occasionally blurred, which is generally common within 3 months after surgery. This is because the cornea generally has mild edema after resting for a night, and there is often discharge when we get up, so this will also affect our vision after waking up to a certain extent.

If your situation does not match the description provided to you above, it is recommended that you go to the hospital for re-examination immediately.

If you are both suitable for the year and the case of caution, you can basically achieve the best corrected visual acuity, the main difference.

1. It is the difference in the size of the incision, the half-fly is a relatively large incision (more than 20mm), and the all-flying incision is 2-4mm

2. Quanfei: The probability of dry eye is slightly lower after Quanfei, and the biomechanical stability of the cornea after surgery is better, but the requirements for doctors' operation are relatively high;

3. The main advantages of half flight compared with full flight: wide correction range, not so high requirements for doctors, and personalized cutting can be carried out for large astigmatism or corneal irregularities.

The degree of myopia of the eye is more than 1800 degrees, which is called ultra-high myopia. This condition is very damaging to the eyes, because the eye axis is elongated, so the retina becomes less and less solid, if you do not pay attention to the habit of using your eyes at this stage or participate in strenuous exercise, it is likely to cause serious fundus complications, such as macular hole, retinal detachment, etc. Therefore, for this situation, it is recommended to first do regular fundus examinations to detect complications early and deal with them as soon as possible. Refractive surgery can also be performed to correct some refractive errors, which can preserve a small degree of myopia, and wear glasses after surgery to achieve good visual quality.

It should be noted that 1800 degrees is a high degree of myopia, which has a high probability of causing fundus lesions, and the symptoms are mainly manifested as degeneration and tears around the periphery, and there is a high probability of splitting in the macular area. When the degree of myopia is 1800 degrees, fundus reexamination must be done every year. At this time, the patient can only correct the vision or through surgery, but the patient still needs to be rechecked every year.

Myopia of 1800 degrees combined with astigmatism of 500 degrees cannot be done for most types of surgery because the luminosity exceeds the limit.

For patients with ultra-high myopia, it seems that the main surgeries that can be done at present are: ICL posterior chamber lens implantation and posterior scleral reinforcement, and corneal surgery seems to be impossible because of thickness limitations.

Myopia eye surgery is conditional:

At present, the myopia eye surgery mainly refers to corneal surgery performed on the cornea, relying on corneal lamellar knife, excimer laser and femtosecond laser, and intraocular lens implantation for the lens.

The surgical requirements for intraocular lens implantation are basically the same as those for cataract removal and intraocular lens implantation, and there are two types of surgery: anterior chamber implantation and posterior chamber implantation, and the specific requirements vary according to different types.

The various corneal surgeries performed by relying on corneal lamellar knife, excimer laser and femtosecond laser have different surgical conditions, but they all require three points:

myopia does not exceed the range permitted for the operation to be performed;

The change in myopia photometry within two years does not exceed degrees);

The surgical area of the cornea ** parenchymal layer thickness is up to standard, the type of surgery using the corneal lamellar knife usually requires the thickness of the parenchymal layer to reach 650 m, and the type of surgery without the use of the corneal lamellar knife (using an excimer laser instead of the corneal lamellar knife) usually requires the thickness of the parenchymal layer to reach 500 m, and the bottom line of this type of surgery is that the thickness of the parenchymal layer shall not be less than 450 m.
