Cataract - How To Identify It?

Cataract - How To Identify It?

A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window.

Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend's face.

Most cataracts develop slowly and don't disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision.

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.

Causes of Cataracts-

Cataracts happen when protein builds up in the lens of your eye, making it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. New lens cells form on the outside of the lens, and the older cells are compacted into the center of the lens, forming the cataract.

Types of cataracts include:

Age-related cataracts: These cataracts form because of aging.

Congenital Cataracts: Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born, or they may develop during childhood.

Secondary Cataracts: These develop as a result of other medical conditions, like diabetes, or exposure to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation.

Traumatic cataracts: These form after an injury to the eye.

Other things that can raise your risk of getting cataracts include cigarette smoke, air pollution, and heavy drinking.

Symptoms of Cataracts-

-Clouded, blurred or dim vision

-Increasing difficulty with vision at night

-Sensitivity to light and glare

-Seeing "halos" around lights

-Frequent changes in eyeglass or contact lens prescription

-Fading or yellowing of colours

-Double vision in a single eye

Treatment-

- Surgery: Surgical removal of a cataract is the first and foremost way of dealing with it. The clouded lens is usually removed and then replaced with a new, artificial lens that will give you improved vision.

- Visual Aids: These aids include lens and eyeglasses that will help you see better after the surgery. Cataract glasses usually come in thick and heavy structure. Also, intraocular lens and contact lens can be used by adults who have undergone the surgery. The constant need to remove, clean and reapply makes it inappropriate for young children. Low vision aids can be used before surgery as well, to ensure that the best use of the remaining vision is made with the help of video enlargement software and other adaptive means.

- Medication: The use of eye drops and other medication can also help in improving vision without the actual surgery for cataract removal. This is a short term solution that can be prescribed by the ophthalmologist whom you visit. The doctor will usually study the extent of the damage and prescribe this kind of medication for cases that are mild. But finally, surgery will have to be carried out as the progression of the cataract is guaranteed in all cases.

- Soft Lighting: At home and at work, you can make use of soft lighting so that there is less pressure on the eye lens. Also, soft lighting will help you see better without the glare blocking your vision in case of the presence of a cataract.

- Avoiding Intricate Work: One must avoid hobbies and work that require unblinking attention or many hours as this can put a strain on the eyes and even lead to severe headaches. This includes painting, embroidery and carving related activities.

Dealing with a cataract is a matter of going in for surgery and making certain lifestyle changes to avoid injuries due to impaired vision.

Cataract Surgery - Know Prior Checks Of It!

Cataract Surgery - Know Prior Checks Of It!

Cataract surgery is performed to remove the lens of the eye and replace it with an artificial one. The surgery is undertaken to cure cataract, which makes the lens of the eyes cloudy, making it difficult to see. The surgery is not considered to be a major one and is performed on an outpatient basis, meaning that the patient can go home the very same day without having to spend the night at the hospital. The procedure is very normal and is undertaken when cataract starts to affect the day-to-day life of the patient.

Know the risks involved
Complications after cataract surgery are rare but not unheard of. The surgery in itself is a simple one but there is a risk of complications if the patient is suffering from another eye disease or is suffering from an underlying health condition. As a precaution, always get yourself tested for other eye diseases before deciding to go for the surgery. Some of the other risks involved include:

What to do before cataract surgery?
Before the surgery takes place, your ophthalmologist will ask you to do certain preparations so that the surgery goes as planned. Make sure that you follow his/her advice diligently for a successful surgery and recovery. Some of these things include:

  1. Undergo certain tests - Before cataract surgery, the doctor will ask you to take certain tests to include an ultrasound of the eye to measure its shape and size. This information will help the doctor to select the right lens for you.
  2. Avoid certain medicines - Your doctor might also ask you to stop taking certain medicines a couple of days before the surgery. Medicines that might cause bleeding during surgery are avoided.
  3. No eating before surgery - The doctor might instruct you to not eat or drink fluids at least 12 hours before the surgery.
  4. Eye drops - You are also asked to apply eye drops in order to reduce the risk of infection to the eye after the surgery.

How To Recover Soon Post Cataract Operation?

How To Recover Soon Post Cataract Operation?

A simple, uncomplicated cataract surgery should not take more than 10 minutes to perform. The best part about a cataract surgery is that most people see almost immediate results and improved vision. However, full recovery can take awhile. Each person heals at a different speed but ideally, your eyes should heal completely in a month.

Here are a few tips to help speed up this process and avoid infections and eye injuries :

Take it easy

Just because the surgery takes a short time is no reason to underestimate its importance. Do not drive on the first day and as far as possible avoid driving for the next few days as well. Do not put any extra pressure on your eyes by bending, lifting weights etc. This will ensure that your stitches do not tear open. Try to avoid excessive sneezing and coughing as this can jerk the lens out of place.

Protect your eyes

Wearing sunglasses is a good idea after a cataract surgery. This will protect your delicate eyes against dust, wind etc. Avoid using community swimming pools and hot tubs immediately after such a surgery to lower the risk of infections. Avoid rubbing your eyes aggressively. For the first week, keep your face out of the shower so as to avoid feeling the need to press or rub your eyes as well as to protect them from bacteria in the water.

Lubricate

Your eyes may feel dry and scratchy after a cataract surgery. This is normal and not something to worry about. Your doctor will prescribe eye drops to be taken after the surgery. Use these regularly. Once this is over you may need additional artificial tears or lubricating eye drops. However, do not take these drops without first consulting your doctor. If your eyes are sensitive to the preservatives in bottled eye drops, look for single use ampoules. Ensure that you always wash your hands well before administering the eye drops.

Keep the eye clean

Though washing your face is avoidable, you must still keep the eye clean. Use cotton and a sterile saline wash for the first few days. You can later replace the saline with cool boiled water.

If you feel any deterioration in your vision, pain or excessive discharge in the operated eye, you must immediately consult your doctor. Seeing sudden flashes of light or floaters in your vision should also not be ignored.

Cataracts - Know Forms Of It!

Cataracts - Know Forms Of It!

Cataract can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, a cataract can be treated with surgery to prevent blindness.

Depending on where and how they develop, there are many types of cataract. The most common amongst these are:

1. Subcapsular cataract

These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.

2. Nuclear cataract

Yellowish-brown cataract that form in the center of the lens are called nuclear cataract. This is usually seen in cataract caused by ageing.

3. Cortical cataract

Cataract in the lens cortex are known as cortical cataract. These are wedge-shaped and whitish in colour. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.

4. Congenital cataract

Though they are not common, babies can also have cataract. Cataract formed at birth or within the first year of a baby's birth are known as congenital cataract.

5. Secondary cataract

Cataract is one of the known side effects of diabetes and glaucoma. Some steroids and medicines are also linked to cataract.

6. Traumatic cataract

If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.

7. Radiation cataract

Exposure to radiation can also lead to cataract. This is seen sometimes in patients who have undergone radiation therapy to fight diseases like cancer.

Though the type of cataract might differ from person to person, the symptoms are usually the same. Some of the common symptoms of cataract are:

1. Blurred vision

2. Reduced night vision

3. Increased sensitivity to light and glare

4. Seeing halos around lights

5. Colours appearing faded

6. Double vision

A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure eye pressure. Your doctor will also need to dilate the pupil to check the condition of the optic nerves and retina.

Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.

In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.

Cataract - How To Avert It?

Cataract - How To Avert It?

We all have only a pair of eyes, so it is imperative that one understands the importance of vision. When the normally clear lens of one’s eye becomes clouded, the condition is known as cataract. A person suffering from cataract finds his vision to be hazy, discoloured and blurred somewhat like looking outside a frosted window. It causes difficulty in reading, driving a vehicle or seeing the familiar expression on a loved one’s face.
It is a silent killer of vision and initially magnification and lighting in addition to vision aids are helpful, but eventually, a surgery becomes imminent. 

The exact reason for cataract are debatable, but one can take measures to protect oneself, boost one’s eyes’ defence mechanisms, and protect them from harmful elements. Ultraviolet (UV) light has been correlated with incidents of cataract and has a damaging effect on one’s eyes. This requires one to wear sunglasses that block ultraviolet B (UVB) rays when one is outdoors. Smoking also increases the risk of cataract thus giving one another reason to stay away from active as well as passive smoking.

One must include antioxidants as zeaxanthin, vitamin C, lutein and vitamin A in the daily diet to counteract with the daily damage. The addition of a variety of fruits and vegetables to one’s diet ensures that one is getting many vitamins and nutrients. The health of the eyes can be maintained with fruits and vegetables as they have many antioxidants. One must go for an eye examination to ophthalmologists in a time-bound and regular manner so to detect the onset of cataract at the earliest.

One must maintain a healthy weight by reducing calorie intake. Excessive consumption of alcohol also increases the risk of cataract. If one is suffering with other health conditions like hypertension and diabetes, it becomes all the more important that one must follow the treatment plan diligently. The exposure to ionizing radiation like X-rays and cancer treatment via chemotherapy increase the risk of cataract.

Cataract develops when aging or injury changes the tissue that makes up one’s eye's lens while some cataract are due to inherited genetic disorders causing other health problems. In some cases, eye conditions, medical conditions such as diabetes, long term usage of steroids, trauma or past eye surgery also leads to cataracts.

As one ages, the eye lenses become less flexible, less transparent and thicker. Ageing causes break down and clumping together of tissues within the eye lens leading to clouding small areas within the lens. As the cataract continues to develop, the clouding becomes denser and involves a greater part of the lens. Thus, although one cannot prevent cataract, but if one takes the above-mentioned steps, then he can reduce the risks of getting it.

Hello lybrate-user. Usually when the cataract matures. It makes it easy to read without glasses but it does not mean that your eye sight is improving. It means the lens visual field is narrowing. And it is obvious to have some numbers depending on the lens used. If you have used simple lense then you may have nubers. More advanced lenses may have been better.

All About Cataract Surgery!

All About Cataract Surgery!

A cataract usually forms in the eyes due to clouding of the naturally clear lens that coats the eyes.This coating is usually a matter of age advancement or any other injury that the eyes may have sustained. It may also be a birth defect that a baby may be born with. There are various ways to deal with this debilitating condition.

One of the methods of treatment includes cataract surgery. Read on to find out more about this form of treatment:

  • Procedure: During this surgery, the ophthalmologist will remove the cloudy lens and clean it before replacing it with a man-made lens.The technique followed for this procedure is known as phacoemulsification which involves a small cut or incision for the cataract surgery. The incision helps the doctor in liquefying and then vacuuming the centre portion of the lens, which is slightly harder than the rest of the lens.
  • Device: The doctor will usually administer anaesthesia first and then make the tiny incision on one side of the cornea. Thereafter, an instrument or device will be inserted through this opening to send out ultrasonic vibrations to the eye. These vibrations will help in breaking the lens into tiny pieces. These fragments will be removed with the help of a suction that will go in through the tiny cut. This cut may also be made with the help of a laser beam.
  • New Lens: Once the fragments of the old lens have been cleared, the doctor will go about the process of inserting the new man made lens which is usually made up of clear plastic, acrylic or even silicon, and is known as IOL or intraocular lens. This process is generally termed as intraocular lens implantation.
  • Improved Vision: With the help of the new lens, the patient will now enjoy better vision and a visible decline in the symptoms of the cataract including problems in night driving.
  • Convenient: This procedure usually takes about an hour and is an outpatient procedure. It is a completely safe procedure where numbing drops are placed on the eye so as to reduce any pain significantly. Also, cataracts from both eyes will not be removed on the same day, and the doctor will schedule you for cataract removal from the second eye for another day.
  • Aftermath: After the surgery is over, it is normal to feel some amount of irritation in the eye. If this irritation is persistent, you must see a doctor about it.

Nowadays, this surgery is done under topical anaesthesia. The duration of procedure is around 30 min. There are a variety of intraocular lens styles available for implantation, including monofocal, toric, and multifocal intraocular lenses. Multifocal intraocular lenses are one of the latest advancements in lens technology. These lenses have a variety of regions with different power that allows some individuals to see at a variety of distances, including distance, intermediate, and near.

Following surgery, you will need to return for visits within the first few days and again within the first few weeks after surgery. During this time period, you will be using several eyedrops that help protect against infection and reduce inflammation. Within several days, most people notice that their vision is improving and are able to return to work. During the several office visits that follow, your doctor will monitor for complications. In most cases, full activity can be resumed after a few days. Once vision has stabilized, your doctor will fit you with glasses if needed. The type of intraocular lens you have implanted will determine to some extent the type of glasses required for optimal vision.

Painkillers like acetaminophen and ibuprofen can be used to recover from the pain after the surgery.
