Can 1000 degree myopia with corneal thickness of 530 be treated with femtosecond laser surgery?

With myopia of 1000 degrees and corneal thickness of 530 within the scope of semi-femtosecond surgery, femtosecond laser surgery can be done.

If the ultra-high myopia exceeds 1000 degrees, especially the ultra-high myopia with astigmatism, the corresponding corneal thickness is very important for the design of the surgical plan. Fundus disease with high myopia is more severe, because myopia is due to the elongation of the eye axis, the higher the power of the eye axis, the longer the eye axis, the thinner the corresponding fundus retina, and the function of the eye decreases. Before the surgery, a corresponding, more cautious examination should be done, and the fundus should be examined in detail to determine whether there are fundus lesions.

Only after the fundus lesions can be ruled out that laser surgery can be safely carried out to correct 1000 degrees of myopia. 1000 degrees of myopia According to the current laser surgery, the cornea needs to consume about 100 m, as long as the corneal thickness is 520-550 m, you can use femtosecond laser to do laser surgery, and you can safely retain enough corneal thickness.

OK. The advantage of femtosecond laser myopia surgery itself is that it reduces the loss of the cornea.

Laser myopia surgery is the "icing on the cake" surgery, which can only be successful and not failing. Therefore, the surgeon is responsible for a comprehensive and detailed preoperative examination, and selecting, collecting and analyzing the examination data of the patients to be operated on is the key first step for the success of the operation. The surgeon's verification of the patient's data and the individualization of the operation are the top priorities for the success of the operation. Surgeons must have rich clinical knowledge of ophthalmology and more abundant surgical experience, because the operation in the operation is mainly instrument control, it seems to be a simple job, in fact, it is more important that doctors with more surgical experience in the operation have more ability to deal with individual differences and solve emergencies; Postoperative education and re-examination are also very important, and timely and appropriate treatment of some abnormal problems after surgery. So choosing a hospital is important!

For patients with thin corneas, laser superficial surgery or intraocular lens implantation** myopia. If the patient's financial conditions allow, it is recommended to undergo intraocular lens implantation with higher comfort, safety and reversibility. For laser lamellar surgery, part of the corneal tissue needs to be removed during the operation, and the remaining corneal thickness of the patient is required to be more than 250mm, or even higher for some special patients, so this method is generally not used for patients with thin corneal thickness.

The amount of cornea to be removed is determined based on the comprehensive data of the patient's eye examination, and the remaining safe corneal thickness must be greater than 410 microns. If you need femtosecond laser surgery, it is recommended to choose Beijing Meier Eye Hospital. Click to test if I am suitable for myopia surgery.

The corneal thickness of the cornea is about 12um per 100 degrees of full femtosecond incisation, and the remaining corneal thickness of 410 microns is retained after each patient's surgery. In laser surgery, for every 100 degrees of myopia corrected, it is necessary to cut to 12 microns of cornea, so the thickness of the single cornea can be laser surgery, and the degree of myopia that needs to be corrected is also very related, and the more corneal thickness is retained, the higher the success rate of the operation, in order to ensure the operation, the hospital will do a lot of preoperative examination on the patient before the operation, including visual acuity, refraction, corneal bean, corneal topography, anterior fundus examination, to determine whether the patient meets the conditions for surgery.

If you want to know more about a femtosecond laser surgery, we recommend consulting Beijing Meier Eye Hospital. Beijing Meier Eye Hospital is one of the hospitals under Meier Medical Group, a designated hospital of Beijing Medical Insurance and the teaching base of Peking University Health Science Center, and is a large-scale professional ophthalmology hospital. The hospital integrates medical treatment, teaching and scientific research, and has international advanced diagnosis and treatment equipment to provide patients with professional and high-quality medical services.

Basically, every 100 degrees of myopia requires the consumption of corneal thickness at 14um (microns). The hospital is a well-known ophthalmology hospital in China, with an annual outpatient volume of more than 10 million and more than 1 million surgeries in Chinese mainland, and a medical service network covering nearly 3 billion people around the world. Click to test whether I am suitable for myopia correction.

Laser surgery is divided into full femtosecond and half femtosecond, which is basically only suitable for people with about 300 degrees to 600 degrees, and many people with high myopia cannot do laser surgery, because the myopia degree is too high, and the corneal thickness may not be enough to cut the cornea if the myopia is more than 1,000 degrees. Femtosecond laser surgery basically consumes a corneal thickness of 14um (microns) per 100 degrees of myopia, while the thickness of the human cornea is different, the thinnest part, the thickness is, and the peripheral part can reach 1mm, so the thousand-degree myopia basically bids farewell to laser surgery.

In femtosecond laser surgery, 90-100 microns are generally incised to make a thin cornea, and 13 microns of cornea are consumed every 100 degrees when the excimer laser cuts the stromal layer.

For example, for 300-degree myopia, do a half-femtosecond excimer laser. The cornea was originally 500 microns, and the postoperative corneal thickness was 500-39 m = 461 m

The femtosecond laser directly penetrates and cuts the corneal stromal layer, consuming 15 m cornea for every 100 degrees of myopia.

Taking 300 degrees and a corneal thickness of 500 m as an example, the postoperative corneal thickness is 500-45=454 m.

The corneal thickness of 490 can be done in full femtosecond, which can achieve the purpose of correcting vision. ReLEx laser surgery is a relatively common vision correction method, which requires an eye test before surgery, and can only be operated when the surgical conditions are met, which can avoid complications during the operation and can also avoid damage to the cornea. During the recovery phase, it is necessary to use the eyes rationally, and only by allowing the eyes to be fully rested can the recovery of vision be accelerated.

After femtosecond laser surgery, the thickness of the cornea is required to be more than 460 microns. You are now 700 degrees myopic and highly myopic and your cornea is 490 cm thick, so you cannot perform this surgery. Because if the surgery will cause the cornea to be too thin, it is easy to cause corneal perforation.

Yes, you need to choose a regular eye hospital. In this way, the effect after surgery will be guaranteed to a certain extent, and the regular eye hospital equipment is more advanced, and the doctor's professionalism is relatively strong.

Femtosecond laser surgery requires the cornea to be at least 460 microns thick. If the surgery causes the cornea to be too thin, it can easily lead to corneal perforation. In these cases, it is advisable to wear glasses all the time, or an intraocular lens implant in the anterior chamber may be considered.

Data on corneal thickness and myopia are entered into the machine, and the instrument helps analyze the thickness that needs to be cut and whether the remaining corneal thickness is within a safe range before deciding whether surgery can be performed.

Contraindicated. 1. Patients with acute conjunctivitis and keratitis.

2. People with keratoconus, glaucoma, severe dry eye and other diseases.

3. Patients with severe amblyopia with extremely poor vision.

4. Patients with scar constitution, diabetes mellitus, and collagen diseases.

5. Patients with proptosis and incomplete eyelid closure.

6. One-eyed patients.

Technical Surgical Risks.

1. Decreased night vision.

After surgery, some people will not be able to see clearly in a low-light environment, and their vision will be reduced at night, and their vision will be blurred.

2. Double vision.

Double vision may occur after surgery, which is detrimental to the driver and will affect driving safety.

3. The effect is not ideal.

People who previously had a high degree of myopia may experience vision loss after surgery, but the desired results cannot be achieved.

4. Corneal flap offset.

If a mistake is made during the procedure, the corneal flap will be displaced and a corneal transplant will have to be performed.

Whether or not you can do femtosecond laser surgery depends not only on the power and corneal thickness, but also on the corneal curvature and fundus condition. But in terms of corneal thickness and power, you are suitable for femtosecond laser. However, the eyes are very precious sensory organs, and for surgery, it is necessary to go to the eye hospital for a detailed examination before deciding, after all, the doctor is the professional.

Corneal thickness 490 is normal, this is not possible, even if there is glare, it can be adapted for about half a year, ordinary people can adapt, yes. The result is the same. It can completely eliminate myopia.

The thickness of this cornea is relatively thin, and whether it can do full femtosecond depends on the specific degree, corneal morphology and other examination results. For example, the corneal thickness can be about 500-600 degrees in full femtosecond, and 600-700 degrees in half femtosecond, and the specific correction degree must be checked by corneal topography and then calculated by formula.

Corneal thickness of 490 can be done with full femtosecond. It is an advanced femtosecond laser instrument, which can promote the symptoms of myopia to achieve a certain improvement, and through the method of making corneal flap and cutting corneal flap, the vision can be restored to normal and the beauty of the eye area can be improved. It is necessary to reduce the time spent with your eyes every day, it is not advisable to look at electronic products for a long time, and you need to do eye exercises to relieve eye fatigue.

The myopia is 1000 degrees, and the cornea is too thin to be eligible for surgery.

The "femtosecond" laser surgery first uses a femtosecond laser device to make a flip-open corneal flap, and then uses an excimer laser to perform corneal ablation in an "ablative" way;

The "ReLEx" laser surgery has changed the traditional surgical method of making corneal flaps, by starting femtosecond laser scanning twice to make a micro-mirror-like corneal tissue diaphragm, and cutting a 2-4 mm superficial small incision above the cornea, you can take out the small lamellar corneal tissue made by femtosecond laser with precise correction degree, so as to achieve the purpose of changing the corneal refractive power to correct vision.

Surgical conditions: first, the age is over 18 years old and under 45 years old;

second, there is no serious disease in the eye;

third, the degree of myopia is relatively stable;

Fourth, after the myopia degree is matched, it is also necessary to check the thickness of the cornea, for example, the patient has 1000 degrees of myopia, but the cornea is too thin, which is not eligible for surgery. The thickness of the cornea should not be less than 450 microns;

Femtosecond laser surgery can correct myopia up to 1000 degrees, and the requirements for the cornea are very high.

Patients who have had 1200 degrees of myopia in our hospital can achieve postoperative vision, which is also very good. Generally, if the cornea is more than 1000 degrees of myopia, if the cornea is unqualified, ICL lens implantation can be done, but for people who are not very old, we do not recommend doing it, because the damage to the eyes is a bit big.
