Cataract is caused by the clouding of the natural lens of the eye and usually develops as a result of old age, but may occur in infants and young children too. This results in blurred vision, glare, and sensitivity to bright lights. Most cataracts develop slowly and don't disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision.
As the disease progresses, it leads to painless, progressive decrease in vision which can also result in a poor quality of life, interfering with day-to-day activities like driving and reading.
A healthy lifestyle helps slow down the progression of cataract, but in case if it has progressed, or if the central vision deteriorates, the only option for its management is a surgery.
At first, stronger lighting and eyeglasses can help you deal with cataracts. But if impaired vision interferes with your usual activities, you might need cataract surgery. Fortunately, cataract surgery is generally a safe, effective procedure.
Cataract surgery in Indore entails sucking out the natural lens after emulsifying it inside the eye by a process known as phacoemulsification. After this, a customized, artificial intraocular lens (called IOL) is placed in its position which restores natural and normal vision.
It's an age related change, comes as an ageing process.
The following are the class of the population who are at an increased risk of Cataract:
No studies have proved how to prevent cataracts or slow the progression of cataracts. But doctors think several strategies may be helpful, including:
To determine whether you have a cataract, your doctor will review your medical history and symptoms, and perform an eye examination. Your doctor may conduct several tests, including:
When your prescription glasses can't clear your vision, the only effective treatment for cataracts is surgery.
Talk with your eye doctor about whether surgery is right for you. Most eye doctors suggest considering cataract surgery when your cataracts begin to affect your quality of life or interfere with your ability to perform normal daily activities, such as reading or driving at night.
It's up to you and your doctor to decide when cataract surgery is right for you. For most people, there is no rush to remove cataracts because they usually don't harm the eye. But cataracts can worsen faster in people with diabetes.
Delaying the procedure generally won't affect how well your vision recovers if you later decide to have cataract surgery. Take time to consider the benefits and risks of cataract surgery with your doctor.
If you choose not to undergo cataract surgery now, your eye doctor may recommend periodic follow-up exams to see if your cataracts are progressing. How often you'll see your eye doctor depends on your situation.
Cataract surgery involves removing the clouded lens and replacing it with a clear artificial lens. The artificial lens, called an intraocular lens, is positioned in the same place as your natural lens. It remains a permanent part of your eye.
For some people, other eye problems prohibit the use of an artificial lens. In these situations, once the cataract is removed, vision may be corrected with eyeglasses or contact lenses.
Cataract surgery is generally done on an outpatient basis, which means you won't need to stay in the hospital after the surgery. During cataract surgery, your eye doctor uses local anesthetic to numb the area around your eye, but you usually stay awake during the procedure.
Cataract surgery is generally safe, but it carries a risk of infection and bleeding. Cataract surgery increases the risk of retinal detachment.
After the procedure, you'll have some discomfort for a few days. Healing generally occurs within eight weeks.
If you need cataract surgery in both eyes, your doctor will schedule surgery to remove the cataract in the second eye after a few days of the first surgery.
To deal with symptoms of cataracts until you decide to have surgery, try to:
Self-care measures may help for a while, but as the cataract progresses, your vision may deteriorate further. When vision loss starts to interfere with your everyday activities, consider cataract surgery.
Make an appointment with for eye evaluation if you notice changes in your vision. Because appointments can be brief, and because there's often a lot to talk about, it's a good idea to be well-prepared for your appointment. Here's some information to help you get ready.
For cataracts, some basic questions to ask your doctor include:
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions at any time that you don't understand something.
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow more time later to cover other points you want to address.
Your doctor may ask:
Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.
Cataract surgery is performed at Saluja Eye Care Center, Indore on outpatient basis, which means you don't have to stay in the hospital after the surgery. Cataract surgery is very common and is generally a safe procedure.
Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, you may be suggested cataract surgery.
When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems, such as age-related macular degeneration or diabetic retinopathy.
In most cases, waiting to have cataract surgery won't harm your eye, so you have time to consider your options. If your vision is still quite good, you may not need cataract surgery for many years, if ever.
When considering cataract surgery, keep these questions in mind:
Complications after cataract surgery are uncommon, and most can be treated successfully.
Cataract surgery risks include:
Your risk of complications is greater if you have another eye disease or a serious medical condition. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.
You will be instructed about preparation before cataract surgery. Your doctor may also advise you to temporarily stop taking any medication that could increase your risk of bleeding during the procedure. Let your doctor know if you take any medications for prostate problems, as some of these drugs can interfere with cataract surgery.
Antibiotic eye drops may be prescribed for use one or two days before the surgery.
Normally you can go home on the same day as your surgery, but you won't be able to drive, so arrange for a ride home. Also arrange for help around home, if necessary, because your doctor may limit activities, such as bending and lifting, for about a week after your surgery.
A week or so before your surgery, your doctor performs a painless ultrasound or optical test to measure the size and shape of your eye. This helps determine the right type of lens implant (intraocular lens, or IOL).
Nearly everyone who has cataract surgery will be given IOLs. These lenses improve your vision by focusing light on the back of your eye. You won't be able to see or feel the lens. It requires no care and becomes a permanent part of your eye.
A variety of IOLs with different features are available. Before surgery, you and your eye doctor will discuss which type of IOL might work best for you and your lifestyle. Cost may also be a factor, as insurance companies may not pay for all types of lenses.
IOLs are made of plastic, acrylic or silicone. Some IOLs block ultraviolet light. Some IOLs are rigid plastic and implanted through an incision that requires several stitches (sutures) to close.
However, many IOLs are flexible, allowing a smaller incision that requires few or no stitches. The surgeon folds this type of lens and inserts it into the empty capsule where the natural lens used to be. Once inside the eye, the folded IOL unfolds, filling the empty capsule.
Some of the types of lenses available include:
Discuss the benefits and risks of the different types of IOLs with your eye surgeon to determine what's best for you.
Cataract surgery, usually an outpatient procedure, takes an hour or less to perform.
First, your doctor will place eye drops in your eye to dilate your pupil. You'll receive local anesthetics to numb the area, and you may be given a sedative to help you relax. If you're given a sedative, you may remain awake, but groggy, during surgery.
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens.
Surgical methods used to remove cataracts include:
This procedure may be performed if you have certain eye complications. With the larger incision, stitches are required.
Once the cataract has been removed by either phacoemulsification or extracapsular extraction, the artificial lens is implanted into the empty lens capsule.
After cataract surgery, expect your vision to begin improving within a few days. Your vision may be blurry at first as your eye heals and adjusts.
Colors may seem brighter after your surgery because you are looking through a new, clear lens. A cataract is usually yellow- or brown-tinted before surgery, muting the look of colors.
You'll usually see your eye doctor a day or two after your surgery, the following week, and then again after about a month to monitor healing.
It's normal to feel itching and mild discomfort for a couple of days after surgery. Avoid rubbing or pushing on your eye.
Your doctor may ask you to wear an eye patch or protective shield the day of surgery. Your doctor may also recommend wearing the eye patch for a few days after your surgery and the protective shield when you sleep during the recovery period.
Your doctor may prescribe eye drops or other medication to prevent infection, reduce inflammation and control eye pressure. Sometimes, these medications can be injected into the eye at the time of surgery.
After a couple of days, most of the discomfort should disappear. Often, complete healing occurs within eight weeks.
Contact your doctor immediately if you experience any of the following:
Most people need glasses, at least some of the time, after cataract surgery. Your doctor will let you know when your eyes have healed enough for you to get a final prescription for eyeglasses. This is usually between one and three months after surgery.
If you have cataracts in both eyes, your doctor usually schedules the second surgery after the first eye has healed.
Cataract surgery successfully restores vision in the majority of people who have the procedure.
People who've had cataract surgery may develop a secondary cataract. The medical term for this common complication is known as posterior capsule opacification (PCO). This happens when the back of the lens capsule — the part of the lens that wasn't removed during surgery and that now supports the lens implant — becomes cloudy and impairs your vision.
PCO is treated with a painless, five-minute outpatient procedure called yttrium-aluminum-garnet (YAG) laser capsulotomy. In YAG laser capsulotomy, a laser beam is used to make a small opening in the clouded capsule to provide a clear path through which the light can pass.
After the procedure, you usually stay in the doctor's office for about an hour to make sure your eye pressure doesn't rise. Other complications are rare but can include increased eye pressure and retinal detachment.
