What kind of lens is suitable for cataract surgery?

Crystal selection is now that there are many kinds of crystals, the first is spherical, aspherical, the visual quality is not the same, the choice of aspherical, the visual quality is higher, this is one of them, there is after the cataract, the intraocular lens is replaced, the intraocular lens is not carried out, the thickness of the adjustment is not clear, now there are some crystals, can carry out some subtle adjustments, can ensure that part of the near, this kind of crystal can also be selected, relatively speaking, it is higher production process, it may ** It will be higher, the third one has some color options, some crystals are colored, such as looking at what we usually see, it is this state, after cataract surgery, its crystal is transparent, more light enters, and it feels like seeing things, it is not the same as what we usually see, some people are very uncomfortable, they feel that you look at the blue is too blue, this white is too white, and you feel uncomfortable, you can also choose to wear a colored crystal, which is a little yellow on it, and the comfort of seeing things is closer to normalIn this way, you can also choose to wear color crystals, and some are after our surgery, some cells grow to this crystal, or grow to the back of the crystal, some tissues, it will have some possibility of re-turbidity, called posterior cataract, such people do not need to do surgery, only need to play laser, but some people in order to reduce, this occurrence may have some coating on the crystal, which can delay this posterior cataract, the development of this situation, it is process, structure, production, can also choose, As long as it's more demanding.

Different intraocular lenses have different prices and can be divided into two categories: hard intraocular lenses and soft intraocular lenses according to their hardness. Rigid intraocular lenses are mainly composed of PMMA materials, and the price of intraocular lenses is generally about 200-800 yuan. Soft intraocular lens is mainly composed of silicone material and acrylic material, folding intraocular lens can be divided into conventional, aspherical and multifocal type, ** ranging from about 100-8000 yuan, some patients may need more special intraocular lens implantation due to special eye conditions, which will be about 5000 yuan more expensive.

You can go to Aier Eye Hospital for a detailed consultation and choose according to your financial ability.

Hello, surgery is the only way to achieve cataracts, mainly by replacing the lens to achieve clear vision.

Intraocular lenses are divided into two types: domestic hard and imported, and the gap is relatively large, but it is also necessary to pass the preoperative examination of cataract patients according to the eye condition of cataract patients, what kind of lens is suitable for them, of course, lenses at different prices, the visual quality and effect after surgery are different. It is recommended that you go to the local professional eye hospital for consultation and examination in time, and carry out cataract surgery in time to prevent the occurrence of cataract complications.

Hopefully, these suggestions you can take thanks

Cataract surgery can be reimbursed, there is a kind of Carl Zeiss 509 crystal, the original price is more than 7000 reimbursement points for more than 3000 points, Zeiss specializes in lenses, and the quality of the intraocular lens is also good. In addition, intraocular lenses are divided into imported and domestic, hard and folded, single and multi-focused, imported folded multifocal crystals are the most expensive, more than 10,000, and the rest range from 2000 to 6000 according to function.

Domestic 500, imported ** ranging from thousands to tens of thousands.

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 for the second eye, it is best to use the same intraocular lens in both eyes; 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.

In addition to the hard and soft crystals, the soft ones are foldable, and the surgical wound will be half smaller.

**Choose medium**, five or six thousand, and three or four thousand after reimbursement is ideal.

Intraocular lens** (estimated):

Rigid intraocular lens (PMMA material): 800 yuan. Surgical incision, apparent postoperative astigmatism (possibly).

Folded soft spherical intraocular lens: 2700 2900 yuan, surgical incision, small postoperative astigmatism (possible).

Folded aspheric intraocular lens: 3800 4100 yuan, in addition to the small surgical incision and small postoperative astigmatism, the postoperative imaging is clearer (there may be a small number of people who will have the opposite effect).

Ultra-thin folded intraocular lens: 5100 yuan, surgical incision, less postoperative astigmatism.

All of the above are monofocal intraocular lenses, and you can't see near if you look far.

Adjustable intraocular lens: 8000 9000 yuan, with a certain visual effect, but with the passage of time, the adjustment effect may decrease sharply.

Multifocal intraocular lens: 8000 12000 yuan, can establish the whole vision, that is, see far, middle and near are free, reading can be done without wearing reading glasses, which is the best choice for cataract patients with strict postoperative vision requirements.

The ** of the selected crystal is different, and the ** of the crystal is usually between 6000 and 6000. In order to restore vision after cataract surgery, an intraocular lens must be implanted according to your needs. IOL is also a major contributor to phacoemulsification of cataract in the eye**.

It varies according to the brand and material. Functional intraocular lenses include astigmatism intraocular lenses, which accommodate intraocular lenses, multifocal intraocular lenses, and astigmatism multifocal intraocular lenses.

The hazards of cataract include: 1. Affecting the quality of vision, thereby affecting the quality of life; 2. Some cataracts can induce the formation of glaucoma, causing irreversible and sharp decline in the patient's vision, causing eye pain and headache. Due to the lack of understanding of cataracts, some patients have misunderstandings about cataracts and believe that they need to wait for cataracts to mature before surgery.

If cataract has caused vision loss and affects the quality of life, you should go to the hospital for examination as soon as possible, detect it in time and operate in time, and do not delay the best time.

There are two types of cataracts: non-surgical and surgical. Non-surgical**: In the initial stage of cataract, eye drops such as catarril, intravacus and other eye drops can be used to control the development.

Surgery**: Cataract vision is below and surgery can be performed as long as the fundus condition is good and the symptoms of systemic disease are not obvious**.

The cost of surgery is not much, basically this kind of surgery does not need to be hospitalized, you can go on the same day, you can go to the hospital at that time, the expensive is the intraocular lens, the domestic is cheaper, the imported one is expensive, the lens is also divided, the cost of not installing the lens is not high, and it can be said to be minimally invasive.

Hello, the current intraocular lens is divided into non-folding and folding intraocular lens, and the domestic intraocular lens is already very good, which can fully achieve the purpose of restoring vision. If there are higher requirements, you can choose imported folded intraocular lenses.

The distribution of intraocular lenses and glasses is relatively similar, according to the material of the intraocular lens, whether it is imported, whether it has a variety of functions, etc.

Classification of intraocular lenses 1, according to the position of placement: anterior chamber type, iris plane type, posterior chamber type 2, according to the characteristics of whether it can be folded: hard crystal (can not be folded), soft crystal (foldable) 3, according to whether the optical part and the material of the fold are consistent:

Three-body type, one-piece 4, according to the design shape of the fold: C-type, J-type, CJ type and other intraocular lens brands 1, the United States ALCON2, the United States Bausch & Lomb 3, the United States EyeHealth 4, the United States OII5, the United Kingdom Rayner6, Japan Itabashi Canon 7, Henan Universe 8, Zhuhai Egger 9, the United States RAFI10, the United States Lenstec11, the United States Emmy 12, Japan Hoya

The cost of cataract surgery ranges from 3000-8000 (single eye), and the cost of cataract surgery is determined according to the cost of the lens.

Phacoemulsification surgery is a minimally invasive surgery, but a certain amount of heat will be generated during the operation, in order to avoid the impact of heat on the cornea, the latest international medical research and development of "cold supermilk" technology. Under the control of a high-level computer, the ultrasound energy is reduced by 4 5, and the temperature of the surgical eye is kept low during the operation, so that the damage to the eyeball is minimized, and the operation is safer. At the same time, the "cold supermammary" technology has been highly praised by cataract patients due to its advantages of light postoperative response, intraoperative **, short operation time, small incision, fast healing, immediate postoperative recovery, and no need for hospitalization.

The American infiniti cold phacoemulsifier introduced by the Department of Ophthalmology of Tianjin 254 Hospital is currently the world's most advanced and safest cataract diagnosis and treatment equipment.

Cataract patients should have an understanding of the relevant knowledge of intraocular lenses before cataract surgery, so as to facilitate the selection of suitable intraocular lenses, at present, there are many types of intraocular lenses, and patients can choose the appropriate intraocular lens according to their own needs and economic conditions.

1. Is the more expensive the intraocular lens, the better?

a. If the operation goes smoothly and there are no other eye diseases, an intraocular lens of tens of yuan to tens of thousands of yuan can obtain satisfactory postoperative vision, so the intraocular lens is not a factor that determines postoperative vision.

b. The difference between a few hundred yuan and a crystal of about two thousand yuan is whether it can be folded.

c. The difference between a crystal of about 2,000 yuan and a crystal of about 3,000 yuan is whether it is aspheric or not.

d. The difference between seven or eight thousand yuan crystals and other crystals is that it takes care of the needs of patients to see far and near.

2. What is the relationship between the choice of intraocular lens and the degree of cataract?

The cataract is less severe, the incision using phacoemulsification is smaller, and a folded intraocular lens is required.

Cataracts are severe, and they are removed using more traditional surgical methods and have large surgical incisions, so there is no need to choose a folded intraocular lens.

3. Does the intraocular lens have a lifespan?

The intraocular lens materials currently used are very good and can remain in the eye for a long time without change, and do not need to be replaced for life after implantation.

4. What is the relationship between the choice of intraocular lens and other diseases?

The choice of intraocular lens has a lot to do with whether the patient has other eye diseases.

a. If it is a simple cataract, the patient can choose any lens according to his economic situation, the adjustable intraocular lens can be selected if the economic conditions are good and the requirements are required to see far and near, and the intraocular lens with obvious astigmatism can be corrected.

b. If it is angle-closure glaucoma, some lenses may be prone to capsular block according to personal experience, and should be avoided as much as possible.

c. If you are a diabetic patient, you may use silicone oil for fundus surgery in the future, and you should try to avoid using crystals that may react with silicone oil.

d. In addition to cataract, there are other diseases such as glaucoma, fundus disease, corneal disease, etc., and the postoperative vision is not expected to be too good.

5. Who chooses the intraocular lens?

Since the choice of intraocular lens requires a certain amount of expertise, it is best chosen by a doctor. In some places, patients choose intraocular lenses, but the patient's choice often does not match their own condition, and they have not benefited from the extra money.
