How can I be sure that the cataract lens is the lens selected before surgery after surgery?

For the average senile cataract patient, basically all intraocular lenses are suitable. Patients can choose an intraocular lens at the right price according to their financial situation. Foldable soft intraocular lenses generally have better postoperative results than rigid intraocular lenses, so patients with conditions should still try to choose soft intraocular lenses.

At the same time, there are many specially designed intraocular lenses that can also be considered, including intraocular lenses that filter blue light, adjustable intraocular lenses, multifocal intraocular lenses and intraocular lenses with aspherical designs. For some special patients, the choice of intraocular lens is also particular, if it is a patient with existing retinopathy, because of diabetic retinopathy, there is the possibility of further fundus surgery in the future, in order to facilitate fundus surgery, it is better to choose acrylic materials or intraocular lenses with heparin treatment on the surface; For the choice of intraocular lens in the second eye, both eyes use the same intraocular lens; In patients with total lens dislocation, no posterior capsule, or complex posterior segment, anterior chamber intraocular lens placement in the anterior chamber may be considered; A sutured intraocular lens may also be used for patients who are unable to have an intraocular lens implanted in the capsular due to a ruptured pouch, for example.

Overall, each specially designed intraocular lens has its own unique features and is designed to provide patients with better post-operative vision. When choosing, you can consider according to your actual situation, and don't blindly think that the more expensive the intraocular lens, the better. Communicate with the doctor before the operation, tell the doctor your needs, listen carefully to the doctor's advice, and believe that each patient can choose an intraocular lens that suits their own conditions.

Crystals have power, just like we wear glasses. It is a convex lens structure, after cataract surgery, the lens is removed, the human eye becomes a state of high hyperopia, implanted intraocular lens, if the prescription is appropriate, the state of farsightedness can be corrected, to achieve emmetropia.

The human lens is generally equivalent to a convex lens of about 20d (2000 degrees), if the patient has 2000 degrees of myopia, the lens is removed to offset the myopia and become an emmetropic eye, theoretically the visual acuity can be achieved, but because high myopia often has pathological changes in the fundus, so the vision will not be like the emmetropic eye.

Intraocular lenses have prescriptions, just like we wear glasses. The lens is a convex lens structure, after cataract surgery, the lens is removed, the human eye becomes a state of high hyperopia, implanted with an intraocular lens, if the power is appropriate, you can correct the state of farsightedness, to achieve emmetropia, that is, no need to wear myopia or farsighted glasses after surgery.

Because the refractive power of each person's eye is different, the natural lens needs to be re-implanted with an intraocular lens after removal, the intraocular lens has a certain power, he according to the different diopters of each person's eye, after the detection of professional instruments, the doctor will calculate how many degrees of lens a person needs to put in, so as to achieve the best postoperative vision, just like giving glasses to teenagers, each child's power is different, so the ** is also different.

The intraocular lens helps to rebuild the refractive system after cataract surgery, and the power of the intraocular lens is calculated based on personal biomeasurements to calculate the most suitable refraction for you, so that you can have satisfactory vision after surgery.

The power of the implanted intraocular lens must be calculated using a highly sophisticated instrument.

The human lens is generally equivalent to a convex lens of about 20d (2000 degrees), if the patient has 2000 degrees of myopia, the lens is removed to offset the myopia and become an emmetropic eye, theoretically the visual acuity can be achieved, but because high myopia often has pathological changes in the fundus, so the vision will not be like the emmetropic eye.

Before surgery, the axial and corneal curvature need to be checked, and the power of the intraocular lens to be implanted is calculated through a general formula, the formula is p=n acd -al-n multiplied by k n-k multiplied by al, p represents the IOC power of the emmetropic eye, n = refractive index of the vitreous humor and aqueous humor, acd = postoperative anterior chamber depth, al represents axial length, k = corneal refractive power.

If the lens can be removed to offset the degree of myopia, the lens can be removed alone, and if the lens needs to be implanted, the intraocular lens can be selected according to the power size. Intraocular lens implantation is now widely carried out in China and has reached the world's advanced level, and there is no risk under normal circumstances.

Now there are many options for intraocular lenses, if the eye does not have fundus disease, and the patient still needs to have accurate distance and near vision in work or life, you can consider high-end intraocular lenses such as bifocal, trifocal and even progressive multifocal lenses, but they are more expensive.

If you do cataract surgery, it is more recommended to Aier Yunqin Eye Hospital, Aier Eye Hospital Group is China's first IPO listed medical first bridge institution, the first medical well-known trademark, and its 100 chain eye hospitals, which is the largest ophthalmic medical institution in China and the largest number of people in China for the correction of myopia.

The problem of eye vision involves a wide range of people and is a major medical and social problem that the masses urgently need to solve. However, judging from the current situation of optometry in China, the content and depth of research are far from enough, and there is still a certain gap with the advanced level of foreign countries.

In order to better develop the domestic optometry industry and improve the academic level, Aier Eye Research Institute carries out relevant scientific research and technological development according to the current scientific frontier and medical development needs of optometry in the world, takes clinical and basic research related to visual function as the leading, and uses the world's most advanced research instruments and equipment as technical support, so as to contribute to the progress of optometry and the visual health of the people. <>

The choice of intraocular lens is very important before cataract surgery, and the choice of intraocular lens must be based on your own conditions and the specific situation of the eye. If the requirements for visual quality are very high, and the economic conditions are relatively good, you can choose aspheric multifocal intraocular lens, if the degree of astigmatism is relatively high, you can choose astigmatism intraocular lens, if the requirements for visual quality are not very high, after the operation, there is no need to drive, read, read newspapers, and their own economic conditions are not very good, you can choose spherical monofocal intraocular lens. Before cataract surgery, it is necessary not only to select the intraocular lens, but also to calculate the intraocular lens.

The choice of lens for cataract surgery is mainly based on one's own conditions. There are many intraocular lenses, if you are a young cataract patient, and the eyes have no other diseases except cataracts, you can choose a better intraocular lens, such as bifocal or multifocal. If you are older and have fundus diseases, you can choose an ordinary intraocular lens in this case, mainly according to your own situation.

Under normal circumstances, cataract patients need to choose intraocular lenses according to their age, living habits and economic conditions before surgery, and also need to measure the power of the lens and cornea. Different patients also have different characteristics, and should be considered from many aspects, so that you can find the right intraocular lens for you, which can also ensure that the eye vision is damaged. There are many aspects that should be considered, so that you can choose the most suitable intraocular lens for you, which can also ensure that there is damage to your vision.

In daily life, we must learn to take care of our eyes and not let our eyes be overtired, which can also play a role in preventing cataracts. During the procedure, the doctor needs to place an intraocular lens in the patient's eye socket. There are many types of intraocular lenses on the market, and the visual effects produced by different intraocular lenses in the process of use will also have obvious differences.

Therefore, it is also very important when choosing an intraocular lens, and you must be cautious. <>

Hard intraocular lenses are relatively cheap in terms of **, and the incision will be larger during the operation, and there is a high probability of astigmatism after the operation. If you have a good budget, it is best to choose a soft intraocular lens, because this lens can be folded, so the incision during the implantation process is relatively small, and the recovery time is very fast. <>

Intraocular lenses also have aspherical and spherical options in shape design, and under normal circumstances, aspheric intraocular lenses will have better visual effects. After the implantation of the monofocal object, you can see the distance of the object clearly, and you will need to wear glasses after the surgery. The refractive intraocular lens is very similar to the physiological lens in all aspects, but the ** of this crystal is also relatively expensive.

Cataract surgery can only be performed once, so it is important to choose the right lens so that it does not affect your life later in life.

First of all, it is necessary to understand the patient's living habits, then figure out the needs of the eyes, and then combine the various types and characteristics of intraocular lenses, and at the same time comprehensively consider the economic situation to choose.

If there are other serious diseases of the eye, which may affect the postoperative results, it is generally not recommended to choose a high-end intraocular lens, in this case, the doctor will propose a specific intraocular lens model according to the patient's condition. If the examination finds that the cornea has relatively large astigmatism, it can be decided to choose an intraocular lens to correct astigmatism according to economic conditions.

Now the cataract surgery through the intraocular lens is very mature, and at the time, the doctor will choose the appropriate lens according to the specific situation of the patient.
