What do I need to pay attention to before myopia surgery?

What to pay attention to before myopia surgery: Before myopia eye surgery, you should first do a detailed examination, consult a doctor, and determine the specific surgical method. Before myopia eye surgery, the doctor usually gives detailed advice.

The first and most important one is to prescribe antibiotic eye drops to reduce inflammation in the eyes and avoid infection after surgery. Once an infection occurs, the patient's vision is affected. Second, fixation training should be done before the operation, which can help the patient cooperate with the doctor during the operation, and the better the patient cooperates, the higher the accuracy of the doctor's surgery.

Because myopia eye surgery is actually grinding a lens on the patient's eyeball, the better the patient's cooperation, the more accurate the lens will be if the eye does not move. If the patient moves his or her eyes, it may affect the quality of the patient's vision.

Before the operation, a detailed examination should be done in the hospital, daily eye maintenance should be carried out according to the doctor's instructions, and fixation exercises should be done.

All attempts to derive from experience such concepts of pure perception, i.e., to the origin of pure experience, by means of concepts of understanding, are futile. For example, the notion of cause does contain a necessity that cannot be produced by experience, a fact that does not need to be specifically asserted by me. Experience shows that a phenomenon usually arises after another phenomenon, and does not show that such succession is inevitable, much less that we can infer the antecedents of the innate and completely universal self-perceived condition.

But as far as the law of association of experience, which we assert that "all things in a series of events are subordinate to the law" (i.e., that nothing comes into existence except that which is universally necessary to follow), which must always be assumed to be fundamental, I will ask what is the basis of which such a law is a law of nature? How is this association possible? The possibility of the association of heterogeneity, within the limits of its existence in the object, is called affinitat.

Then I will ask, how can we make ourselves understand the "consistent affinity of phenomena" of the immutable law of subordination and necessity to which phenomena are caused?

According to my principle, this is easy to solve. All possible phenomena, with their appearance, belong to the totality of a possible conscious consciousness. But since conscious consciousness is a transcendental appearance, the identity of the number (i.e., the same invariance) is inseparable from it, and it is an innate certainty.

Nothing can enter into our knowledge except for the unity of this source. Now this identity is a necessary entry into the synthesis of all the miscellaneous phenomena, so that within the limits of the knowledge of this synthesis to which the experience is produced, the subordination of phenomena, to which all the synthesis of phenomenal perception must be perfectly identified, the innate condition. The appearance of a universal condition, the one which can be set in the form of a uniform form by the beginning of a certain heterogeneous basis, is called a law, and when it must be set as such, it is called a law.

Thus all phenomena are connected in a consistent way according to the law of necessity, i.e., in a priori affinity (the affinity of experience is only its consequence).

There are certain requirements for myopia eye surgery, and it is necessary to meet the requirements in order to perform safe laser surgery, which are as follows:

1. Exclude active ocular disease: there can be no systemic diseases, such as diabetes mellitus and immunosuppression, and surgery is not recommended for these patients.

2. The expectation of surgery is too high: the operation should be cautious, and the age should not be too young, generally required to be over 18 years old, and the refractive state should be stable in the past two years, that is, the annual degree change can be within 50 degrees.

3. There are requirements for the degree of prescription: different laser surgeries require different degrees of myopia, lamellar corneal surgery generally cannot exceed 1200 degrees, femtosecond laser surgery cannot exceed 1000 degrees, and superficial surgery generally does not exceed 800 degrees.

3. There are requirements for the thickness of the cornea: after the cornea is removed, the thickness of the remaining corneal stromal layer should be at least 250mm, and it is recommended to be more than 280mm.

4. Pupil diameter: For example, the value in dark light and low light, if the pupil diameter is too large, it may cause astigmatism after surgery, resulting in poor night vision. Want to have femtosecond myopia surgery and don't know where to do it?

It is recommended to find Huashi Ophthalmology, which is a national chain of large-scale ophthalmology hospitals, which makes people feel more at ease and more worry-free after postoperative reexamination. Not only the service is high-quality, but also cost-effective, and the price is medium, so that the people of the country can save worry and money. Learn more about this

Myopia surgery, mainly including corneal refractive surgery and intraocular refractive surgery, is mainly used for refractive error**, which has been widely carried out in clinical practice. Its curative effect is also relatively certain, which can effectively improve corrected vision and achieve the purpose of removing glasses. However, because it is an invasive procedure, it is bound to bring some common complications, such as overcorrection, refractive regression, dry eye, subjective appeal to optical aberrations, corneal interlaminar debris, corneal neurotrophic epithelial lesions, diffuse interlamellar keratitis, infectious keratitis, progressive corneal ectasia, etc.

However, these complications are less likely than the need for surgery. Therefore, it is advisable to choose carefully before surgery, especially for patients with high expectations. As the Jinan Branch of Huaxia Eye Hospital, under the leadership of Director Wang Lihua, it has strictly abided by the criteria of precise technology and safe surgery for many years, and has made continuous progress to strive to do a good job in all eye surgeries.

Do myopia surgery, pay attention to the rest of the eyes, and have enough energy to meet the hands.

Hello, precautions before myopia eye surgery, experts said that there are some things to prepare before doing excimer laser **myopia. Stop wearing your contact lenses two weeks before surgery. Apply the eye water prescribed by the doctor 1 to 3 days before the surgery.

Before laser surgery for myopia, you should pay attention to go to the hospital for the corresponding preoperative examination, evaluate whether it is suitable for surgery, and check the visual acuity, intraocular pressure, and corneal thickness

It's also this love that makes me want to live, but I keep telling myself that I don't want to see those who say goodbye in this life or in the next life, because this world will not come in the next life.

The contraindications before myopia surgery are: 1. Patients who have undergone surgery must be over 18 years old before they can do it. 2. The thickness of the cornea of the patient must meet the standard of laser surgery, otherwise there will be postoperative vision loss.

Preoperative testing is required.
