myopia operation safe? Does myopia operation have sequelae? This is most people’s question about myopia surgery.

bad habits cause myopia

1. Improper light intensity -. When reading and writing, whether the light is too strong or too weak, it will easily lead to myopia. Too strong light can easily make the eyes feel tired, which is one of the reasons for myopia. The best way to wait is soft light, and make sure the light comes from the front left.

2. Glasses are too casual -. Many people are afraid that they will not go to regular hospitals to match glasses. The optometry in some glasses stores is inaccurate, the degree is not standard, and the quality is not up to standard- In this way, the eyes are easy to fatigue and the degree is easy to increase.

3. Books, paper and printing are too “exquisite” -. In today’s era, the printing of many books is becoming more and more gorgeous and exquisite. In fact, these exquisite books may also hurt your eyes. Coated paper is too reflective, especially at night, shaking your eyes. This dazzling light is called glare in medicine. It makes you less clear what you want to see, makes your eyes more tired, and may also be the cause of myopia-

4. Too little time for outdoor activities -. Now many people don’t like outdoor activities and are used to facing computers or TV for a long time. This will cause a lot of close eye use, and the eye adaptability is very strong. It will adjust itself to adapt to this close distance. Moreover, more time in the house, more opportunities to watch TV and play computer. If you don’t pay attention to distance and posture, it’s easy to make your eyes too tired-

preparation before myopia surgery

1. Visual acuity examination: This is one of the most basic examination items before myopia surgery. Patients with myopia include vision without glasses and best corrected vision with glasses.

2. Refractive examination: there are three steps: initial examination, mydriatic optometry and retest. Whether the diopter is correct or not directly affects the effect of myopia surgery.

3. Examination of anterior segment and fundus: before myopia surgery, check whether the corneal transparency of patients with myopia has scars, whether the lens is turbid, and whether there are vitreous opacity and fundus lesions. This is one of the inspection items before myopic surgery.

4. Corneal thickness measurement: for myopia patients with corneal center thickness less than 500, if the myopia patient is highly myopia, pay attention to the cutting depth of corneal center, and explain the relevant situation to the patient before myopia surgery. This is also one of the inspection items before myopia surgery.

5. People suitable for surgical treatment of myopia: 18 to 50 years old, myopia with stable degree in recent two years, 150 to 2000 degrees, or combined astigmatism of 100 to 400 degrees, and hyperopia of 200 to 800 degrees are suitable for treatment. Myopia should stop wearing contact lenses for two weeks before operation. Ocular infection, keratoconus, glaucoma, cataract, fundus disease, and other systemic diseases such as diabetes and collagenous diseases are not suitable for myopia surgery.

misunderstanding of myopia surgery

1. Some people think that for myopia surgery, the higher the degree, the better the effect. This view is wrong, but myopia often puts forward such problems in clinic. As long as the preoperative examination is determined to be suitable for the operation, the postoperative effect is quite good, and the lower the degree, the faster the visual acuity of myopia patients will recover. It is only after the operation that the myopia with high degree suddenly feels a lot clearer, while the myopia with low degree may not feel much different from that before the operation, so some people think that the operation effect with high degree is better.

2. After myopia surgery, as long as you pay attention to eye hygiene and use your eyes reasonably, myopia will not relapse. Such a view is wrong. The operation is carried out in a safe and stable environment. Before operation, a detailed examination should be carried out to determine whether the patient can perform the operation. And the degree should be stable for more than two years, which is conducive to the recovery and stability of postoperative vision.

3. Surgical treatment of myopia can not treat hyperopia and astigmatism. Excimer laser surgery can also treat hyperopia and astigmatism, but it is required that hyperopia is less than 600 degrees and astigmatism is less than 600 degrees. Other surgical conditions are the same as those for myopia.
