Cataract is a disease that often occurs with aging. the cataract surgery is necessary if the conditions are quite significant cataract and interfere with daily activities.
A cataract is a clouding that occurs in the lens of the eye. Normally, the lens of the eye in the form of a clear and transparent structure. In patients with cataracts, blurred vision clouded the cause of the lens as the next.
blurred or hazy vision.
Sensitive to light. Sometimes when he saw the lights like a halo (halo).
If you see with one eye, objects can be seen twice.
When seen, the color of an object are like the patients of cataract or yellowish brownish.Eventually view, it would be difficult to distinguish between blue and violet.
vision problems can deteriorate gradually, which can often change the lenses.
So far, no one knows exactly why cataracts form. Aging is a risk factor. Cataract due to aging is called senile cataract.
occur not only in the elderly, although rarely, cataracts occur in children or newborns. The causes are congenital infection, hereditary enzyme abnormalities and other genetic diseases. In addition, the cataract can be triggered by trauma to the eye, exposure to sunlight for a long time, smoking, diabetes or the use of certain medications.
Basically clouding minor or moderate cataract in the lens is a part of aging. This condition may not require medical treatment like surgery. However surgery is necessary when a fog on the lens is severe it interferes with daily activities such as reading or driving, and when vision can not be helped with glasses.
Before doctors decided to carry out the surgical technique of cataract or grow, what kind of lens, a doctor may perform a test that uses ultrasound waves orpainless ultrasound tests. They can also be used for 1-2 days before the operation, if necessary using a promoted drops. Do not use drugs, and should not eat or drink for 12 hours before surgery.
Generally lens opacities exchange cataract surgery of the eye of the experiment indicated by planting plastic lens called intraocular lens or IOL. There are several techniques of operation, namely:
work phacoemulsification with small incisions near the cornea.Next, put a small tool and its use by ultrasonic vibrations, is to destroy the opaque lens. The lenses are then destroyed sucked with the same tool. This technique is performed more frequently.
the cataract surgery with minimal incisions (micro-incision cataract surgery) is a cataract surgery technique that is less than 1.8 m.
Ekstrakapsuler cataract surgery, surgical incision far enough in the view, so you can intact cloudy lens. This technique is for those who have already covered the major part of the lens cataract. After surgery, the medical staff will inject the drug around the eyes.
Intrakapsuler cataract surgery is a technique that is rarely the case. This technique is for those who have suffered major trauma. larger than the above two techniques, because of the need to simultaneously lift the capsule surrounding the lens while the incision is required.
After the lens is removed disorder, doctors will be replaced by an artificial intraocular lens. Several types of intraocular lenses as follows.
Torik lens, myopia or astigmatism or cylinder helpful to help.
monofocal lens can only on the track, the approach is short-sighted for the eye.
multifocal lens can focus at different distances in a short distance behind, intermediate and distance.
A few hours after surgery, you can go home. Indeed, operation is used as a local anesthetic. In addition to the operation was carried out in a relatively short time, which is about half an hour to 50 minutes. However, it is recommended to use the help of others, to go home because you may not see perfect would have been possible. The eyes may be sensitive to light, blurred vision and itching for a few days after surgery.
The following steps can help the recovery of postoperative eyes.
Avoid touching your eyes.
Use eye drops as recommended by doctors to relieve postoperative symptoms.
Never push objects of any kind into the eye such as water and soap.
Usually after cataract surgery, you need glasses nearsightedness or farsightedness or a combination to run both. Indeed, the lens implant can not focus on a particular distance.
After surgery, the eye can be fully recovered in about two months. Most people’s vision after surgery are improved. You can see the light without glare, you can distinguish colors because it seems brighter, and see the object that has focus.
The risk of cataract surgery
The risk of cataract surgery, infections, pressure changes in the eye, bleeding and other complications. The most common complication is the opacification of the posterior capsule (posterior opacification / PCO capsule). PCO causes blurred vision back.
Your doctor immediately if you experience in the state of postoperative ocular redness, pain achieved despite taking painkillers, nausea and vomiting or persistent coughing and loss of vision.
