Is it a lens problem that cataract surgery is blurry after surgery than before surgery? 10

There are two main possibilities for blurred vision after cataract surgery: one may be normal and the other may be corneal edema. Blurred vision on the first day after cataract surgery may be normal.

If symptoms persist, corneal edema should be considered, symptomatic examination is recommended, and ophthalmologic examination** is recommended. Abnormalities to be aware of after cataract surgery are sudden eye redness, eye pain, or rapid loss of vision.

Blurred vision after cataract surgery is not necessarily due to the lens, but can also be caused by:

1. Abnormal lens regulation function can affect vision: the adjustment function of the lens of normal people, people can see far things and near things clearly, after the intraocular lens is fixed, see the distant things and near things can not be taken into account, in order to achieve better vision, generally can go to the hospital for physical examination after the wound heals three months after the operation.

2. Causes of fundus lesions: Before cataract surgery, the doctor should conduct relevant examinations on the patient's friends, because the cataract itself is diseased, so the transparent lens is no longer transparent, which will be equivalent to the examination of other parts relatively speaking, as well as the correct judgment and corneal dystrophy or lesions, which will also affect the vision after surgery to a certain extent.

3. Posterior cataract: Posterior cataract is mainly manifested as a particularly good vision after surgery, but the vision will decline after a period of time, many people think that it is a problem with surgery, but in fact, this is because the doctor in order not to destroy the normal physiological structure of the eye during the operation, in order to better insert the intraocular lens, retain a layer of film during the operation, play a supporting role, in a period of time after the operation, nearly 1 3 patients will gradually become cloudy, so it will affect the vision.

If your vision is blurred after cataract surgery, it is recommended to go to the surgery hospital to check with the surgeon to see if it is caused by recovery or other reasons.

Cataracts are a common blinding eye disease. There is a tissue in the human eye called the lens, which is normally transparent, and light rays can reach the retina through it and some refractive interstitium, so that external objects can be seen clearly. Once the lens becomes cloudy for some reason, it will affect the imaging of the retina and make it difficult for a person to see clearly.

In other words, vision loss due to lens opacity is a cataract. It is recommended to be prompt when cataract is found or has been diagnosed, and to avoid long-term overuse of the eyes.

Natural crystals have a capsule, that is, the lens capsule, which is divided into intracapsular and extracapsule extraction according to the relationship between the lens nucleus and the capsular pouch during surgical removal. After the removal of the cloudy crystals, an intraocular lens is often inserted, which can be placed in the anterior or posterior chamber, and in the posterior chamber, it can be in or outside the capsule. In addition to restoring vision, the placement of an intraocular lens can also restore the anatomy within the eye and prevent the prolapse of the anterior vitreous humor, which may cause traction to the retina if the anterior vitreous cavity prolapses into the anterior chamber and the cornea or iris tissue.

Cataract intracapsular extraction (ICCE): A large incision is made to cut the corner of the scleral limbus, and after entering, the lens is frozen with a cryohead, and the suspension ligament is ruptured by pulling outward, and the lens is delivered.

Extracapsular cataract extraction (ECCE): Switch-and-switch capsular resection to deliver the lens.

Phacoemulsification crystal extraction (PHAC): continuous annular capsular tearing, phacoemulsification of the lens nucleus, perfusion and aspiration of the lens cortex, implantation of intraocular lens.

Maintenance: (1) Eat more fresh vegetables and fruits rich in natural vitamin C, such as celery, cabbage, greens, tomatoes, strawberries, citrus, fresh dates, etc.

2) Eat more grains, green vegetables and lettuce, carrots and tomatoes, especially citrus fruits, grapes, lemons, bananas and apricots. Also eat calcium-containing foods regularly.

3) Avoid drinking and smoking, and eat less animal fat and sugar.

Hello, it is necessary to change the lens, and the cause of cataract is very related to the cloudiness of the lens

Cataract surgery requires lens replacement.

It is necessary to implant an intraocular lens during cataract surgery, mainly because of the principle of the operation. Surgery involves completely crushing and sucking out the cloudy lens in the eye and replacing it with an intraocular lens, so that the eye has a complete structure, just like comparing the eye to a camera, and the lens is equivalent to the lens of a camera. Now there is a problem with the lens, and you need to replace it with a new one, if you simply remove the lens, but do not install a new lens, the eye will not be able to see, so it is necessary to install an intraocular lens.

Cataract is a process of crystal turbidity, not to say that a cataract grows, it is a process in which a transparent lens becomes opaque, just like our spectacle lens, from a usable spectacle lens to a non-usable spectacle lens, at this time, we have to remove the turbid lens through a surgical method, and then replace it with a transparent crystal, this transparent crystal, we call it an intraocular lens, that is, the intraocular lens must be replaced. Almost all cataracts need to be replaced with this intraocular lens, but there is a category, for example, a candidate with high myopia, he may not have a suitable intraocular lens, at this time, it may be said that it will be assisted by external lenses, which actually plays the role of a lens.

However, there is no way for normal people to be assisted by this external lens, because this lens is equivalent to a height of more than 1,000 degrees of farsightedness, and if people wear these glasses, they will feel dizzy and dizzy, and there is no way to adapt, so we recommend implanting this lens into the eye, and there will be no such feelings.

Mild cataract can be used to help delay the disease, if the patient's vision has been affected, surgery should be considered**, cataract patients in the process of surgery**, if the lens is not cloudy, only a little yellowish, no cataract, ICL implantation can also be considered, but if the patient's lens is more cloudy, it is best to implant an intraocular lens. The above is Quanzhou Aier Eye Hospital to tell you, if you still have any questions, it is recommended to go to the hospital for a detailed consultation.

After cataract surgery, due to the influence of the incision, the curvature of the cornea will undergo some changes, and there will often be a certain degree of astigmatism after the operation, which will affect the vision. At this time, three months after the operation, after the wound has healed, optometry can be performed.

In addition, corneal endothelial damage is caused during surgery, corneal edema occurs after surgery, and blurred vision can also occur after cataract surgery. This condition can be actively treated with eye drops containing hormones, which usually recover within one to two weeks.

In addition, there is a relatively rare condition in which vision loss accompanied by visual distortion occurs about two months after surgery, which is medically known as cystoid macular edema. This is a mild complication after cataract surgery that usually resolves on its own in about six months.

Blurred vision is not related to shallow anterior chamber. Shallow anterior chamber is related to intraocular pressure, which may be high. If you have been implanted with an intraocular lens and your vision is still blurred one week after surgery, there are three possibilities:

The diopter of the chosen intraocular lens is not suitable; There may be edema in the fundus that does not resolve; You may have old damage to your optic nerve.

If there is a refractive problem (myopia, farsightedness, presbyopia) before the operation, the clarity of the two eyes is different, and the vision caused by the cataract may be blurred, so that the feeling of refractive error is not obvious, but after cataract surgery, the visual effect is clear, and the feeling of refractive problems such as myopia and presbyopia becomes obvious. However, if you choose an ordinary intraocular lens for cataract surgery, it does not have the function of adjusting refraction, so you need to go through formal optometry glasses to adjust after surgery, and you can't just buy a pair of reading glasses to wear.

It should be a problem with the lens, which is cloudy and degenerative due to aging degeneration, diabetes, metabolic disorders, developmental disorders, trauma, etc., which is cataract.

One surgery may not be thorough.

Cataract surgery replaced the intraocular lens, which is exactly the same as a normal person's eyes, and there is no difference from the outside**, if the operation is successful, his vision is not bad.

Normal, there is no difference, you must take good care of your eyes one month after surgery, look less at your mobile phone, watch less TV, and computer, which will help your eyes recover.

After the replacement of the intraocular lens, the eyes look no different from normal eyes, and there is no difference in how they can see.

Cataract surgery can be solved without lens and by wearing aphakless glasses (frame) and contact lenses. However, the most ideal method is to install an intraocular lens.

After cataract removal, the lens is lost in the eyeball, and vision is still unclear, and wearing aquakic glasses (frame) and contact lenses have many disadvantages or shortcomings, so the ideal method is to install an intraocular lens to restore vision and visual field to normal. Under normal circumstances, an intraocular lens can be used for a lifetime after it is implanted.

It is not possible to do without a lens after cataract surgery, because the cause of cataract is poor vision caused by lens opacity, so cataract surgery should remove the original lens and then place a new intraocular lens to help the patient regain his vision, and if the lens is not placed, there is no way to fundamentally solve the problem of cataract.

Sometimes there may be a failure to place the place requiring a second surgical placement.

Hello, it is not possible to leave the lens after cataract surgery.

The principle of cataract surgery is to replace the original cloudy lens in the eye through an intraocular lens to help cataract patients restore their vision.

Cataract patients have high farsightedness in their eyes when the original cataract lens is removed, and if the cataract patient's eyes are not replaced with a new intraocular lens, it will not help the patient's eye vision.

Intraocular lenses are naturally not as good as their own lenses, but after the natural lens is cloudy, it has a greater impact on vision and eye health, so it should be replaced by intraocular lenses. Cataract surgery, on the other hand, is a surgery to remove the cloudy natural lens and implant an intraocular lens.

In intraocular lenses, different lenses have different visual effects, so cataract surgery has a certain impact on the postoperative visual effect and life ** when choosing an intraocular lens. Intraocular lenses are divided into two categories: monofocal lenses and multifocal lenses according to their different functions.

1. Unifocal intraocular lens:

There is only a single clear focal point, and depending on the target diopter, it is possible to see clearly near (with corrective glasses when seeing far) or far with clear vision (with corrective glasses when seeing near). The two commonly used monofocal lenses are ordinary aspheric lenses and Toric intraocular lenses, which can correct preoperative corneal astigmatism.

If the patient is detected with corneal astigmatism before surgery, the use of a common intraocular lens will result in blurred and distorted vision, and two pairs of glasses may be required for near and far vision, or further refractive surgery. Toric intraocular lens is an astigmatism correction intraocular lens that can effectively correct astigmatism and improve vision while relieving cataracts.

2. Multifocal intraocular lens:

It is an intraocular lens with the latest technology, which can achieve far, medium and near vision. Whether it is near vision (reading books, reading newspapers), middle vision (looking at mobile phones, looking at computers), and far vision (going out shopping, sports), you can maximize the postoperative lens removal (the removal rate is about 80% to 90%), get rid of the shackles of glasses, and make work and life easier.

Identity, because it's an intraocular lens, I think it's still identity.

The body's own crystals, which are certainly the best in healthy conditions, have self-regulating functions. However, as the lens becomes cloudy, the cataract deepens, and the quality of vision decreases, causing multiple problems, and the replacement of the problematic lens by the intraocular lens is also a way to improve the quality of life.

At present, cataract lenses are well developed, and there are many types of choices, including monofocal, bifocal, and trifocal, which can be selected accordingly according to their own conditions, among which high-end trifocal lenses are very good for postoperative far, middle and near, and night vision recovery is very good, and the visual quality is also very good.

In addition to the choice of intraocular lens, the visual quality after cataract surgery is also related to the degree to which the brain adapts to the intraocular lens.

There are many causes of vision loss, such as common cataracts, vitreous diseases, fundus diseases, etc., so if the vision recovery after cataract surgery is poor, it is recommended to do a fundus examination to determine whether there is any fundus disease.

Within a day or two after cataract surgery, the vision will be blurry because of corneal edema, and the edema will subside over the next few days

Generally speaking, before the operation, the doctor should examine the patient's red-green perception, light positioning, B ultrasound, visual electrophysiology and other items, due to the lesion of the cataract itself, it also affects the doctor's observation and diagnosis of other eye diseases such as glaucoma and macular degeneration.
