Cataract Surgery - What You Should Be Aware Of?

cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually, develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.

Types of cataracts:

  1. Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
  2. Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
  3. Traumatic Cataract: It can develop many years later after an injury caused to your eye.
  4. Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes. 
  5. Radiation Cataract: It can form after you are exposed to some form of radiation.

cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.

Why does it happen? 

There are lenses that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it. 

However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.

Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few. 

When should you opt for a cataract surgery?

Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightednessor alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night.

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 by an eye doctor (ophthalmologist) on an 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.

How a cataract affects your vision

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, your doctor may suggest 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:

  1. Can you see to safely do your job and to drive?
  2. Do you have problems reading or watching television?
  3. Is it difficult to cook, shop, do hardwork, climb stairs or take medications?
  4. Do vision problems affect your level of independence?
  5. Do bright lights make it more difficult to see?

Risks

Complications after cataract surgery are uncommon, and most can be treated successfully.

Cataract surgery risks include:

  1. Inflammation
  2. Infection
  3. Bleeding
  4. Swelling
  5. Drooping eyelid
  6. Dislocation of artificial lens
  7. Retinal detachment
  8. Glaucoma
  9. Secondary cataract

Loss of vision

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.

Clouded Vision - Is It Cataracts?

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, 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

A yellowish-brown cataract that forms in the center of the lens is called nuclear cataract. This is usually seen in cataract caused by ageing.

3. Cortical cataract

Cataract in the lens cortex is known as cortical cataract. These are wedge-shaped and whitish in color. 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 a cataract. Cataract formed at birth or within the first year of a baby's birth is 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.Colors 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.

Which Eye Tests That Are Conducted Before Surgery?

Which Eye Tests That Are Conducted Before Surgery?

Any patient who needs to undergo cataract surgery must be evaluated in a thorough manner so as to establish the requirement, appropriateness, expected surgical problems, expected benefits and co-morbid conditions having an influence on cataract surgery.

The preoperative assessment consists of -

A test for your existing glasses prescription:

It is useful for your cataract surgeon to know your existing glasses prescription in cases where there is a high refractive error (people who are very short or long sighted), in order to plan to correct this error after cataract surgery.

A full ocular examination: This includes looking at:

  • The eyelid anatomy and inflammation.
  • The state of the tear film, dry eye changes could make surgery difficult
  • The presence of abnormalities in the cornea that could make visualisation of the cataract difficult during surgery.
  • The amount of dilation the iris undergoes with dilating drops.
  • The type of cataract. Soft cataracts can be aspirated. Hard cataracts need more ultra-sound energy and surgical time to break up and remove. White cataracts may need trypan blue staining to visualize the capsule
  • The measurement of intra-ocular pressure. With this test, we aim to exclude glaucoma and ensure optimal control of immediate pre-operative and intra-operative eye pressures often with extra eye drops that temporarily lower eye pressure.

Biometry Tests: This is a simple pre-operative measurement. It calculates the correct power of artificial intra-ocular lens. They will be implanted into your eye once your cataract is removed.

Corneal Topography: This is a test to map out the corneal curvature in greater detail. It is used prior to premium IOL Implantation like Toric IOLS either monofocal or multifocal , to ensure avoid postoperative refractive errors. This extra test is only required if the biometry readings show larger than normal differences in keratometry readings.

Optical Coherence Tomography (OCT): This test allows detailed visualisation of the macula (the central sensitive part of the retina used for fine vision). If the ophthalmologist suspects any macula changes that may prevent a patient from visual improvement after cataract surgery, he always suggest optical coherence tomography.

Blood Pressure Measurements: It is very important to know your blood pressure measurements before your cataract operation. The risk of having a bleed at the back of your eye during cataract surgery (supra-choroidal haemorrhage) is very small (1 in 10000). But is higher if you have uncontrolled blood pressure.

Blood Sugar Measurements in Diabetic Patients: Cataract surgery itself does not affect your blood sugar measurements if you are diabetic. A routine checkup of blood sugars in diabetics before cataract surgery is done and the surgery if often delayed if the levels were greater than 20mmol/L as the risk of post-operative infection is higher.

Dealing With A Cataract

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 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.Avoiding Intricate Work:

- Clouded, blurred or dim vision

- Sensitivity to light and glare

- Seeing "halos" around lights

- Frequent changes in eyeglass or contact lens prescription

- Fading or yellowing of colors

Treatment of Cataract - 

- 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 eye glasses 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 re apply makes it inappropriate for young children. Low vision aids can be used before surgery as well, to ensure that 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.

How Cataract and Phaco Surgery Can Help?

Cataracts are a common eye problem experienced by the elderly. In some cases, babies may also be born with cataract as a congenital defect or it may develop as a result of conditions such as diabetes. Cataracts can affect one or both eyes and is characterized by the clouding of the lens in the eye. This can make it difficult to see clearly and if not treated in time can lead to blindness.

Common symptoms of cataract include:

  1. Blurred vision
  2. Nearsightedness
  3. Changes in the perception of colour
  4. Night blindness
  5. Increased sensitivity to glares
  6. Double vision

An eye examination is the first step to diagnosing cataracts. To confirm a diagnosis the doctor will also dilate the pupil to check the lens. Most cataracts can be easily treated with surgery. This surgery involves the separation of the cataract from the lens and its removal after which an intraocular lens implant is placed in the eye. In cases where this cannot be used, corrective contact lenses or glasses will need to be used. One of the most popular methods of cataract surgery is known as phaco surgery or phacoemulsification.

This surgery involves making two, small incisions on the eye where the cornea meets the sclera. This is then used to create a circular opening in the lens through which a probe is inserted into the eye. Sound waves or laser is then used to break the cataract into small pieces. This is then removed from the eyes and an intraocular lens implant is put in its place. Stitches are rarely required for this surgery and it is usually performed as an outpatient procedure while the patient is under local anaesthesia. When treating cataract, both eyes are usually not addressed simultaneously.

This surgery is usually pain free. The operated eye may be bandaged overnight and the patient will be given a protective eye shield to be worn for a week. The doctor will ask you to get a check up 2-3 days after the surgery where they can evaluate the clarity of the lens, overall health of the eye, eye pressure and visual acuity.

Cataract surgery is generally considered to be a safe surgery but like any other surgery there are risks involved. Some of the possible complications of this type of surgery include:

  1. Pain and redness of the eye
  2. Vision problems
  3. Swelling of the eye
  4. Discharge from the eye
  5. Flashes or floaters in the patient’s vision
