A cataract is the name given to the condition where the natural
lens of the eye is not crystal clear.
What is cataract surgery
A cataract is the name given to the condition where the natural lens of the eye is not crystal clear. Cataract surgery is the procedure of removal of the cloudy natural lens of an eye and replacing it with a plastic artificial lens implant. It is performed by an eye surgeon (ophthalmologist).
Surgery is necessary because cataract can cause blurred vision and other vision problems.
Cataract surgery is also known as lens replacement surgery. The procedure is painless, and in most cases restore good quality of vision.
Symptoms of Cataract
Cataracts are usually not painful. You know you need to see a doctor if your vision is not as clear as it used to be, either for distance focus, near focus, or both. You may also have some of the following symptoms:
1. It is hard to see at night.
2. Sensitivity to light.
3. Seeing a “halo” around bright lights, such as street lights or car headlights.
4. Seeing double vision or ghosting of images.
5. Colors do not seem as lively or vivid as they used to.
When to see an eye doctor?
Make an appointment for an eye exam if you notice any changes in your vision. If you develop sudden vision changes, such as double vision or flashes of light, sudden eye pain, or sudden headache, see your doctor right away.
Causes of Cataract
Most cataracts are related to the normal ageing process.
The lens tissue in human eyes naturally accumulates proteins and hardens with time, leading to a gradual reduction in clarity. Everyone will eventually develop cataract if they live long enough.
Cataract can also be caused by health conditions such as diabetes, previous eye trauma and surgery, as well as medications such as steroids.
Certain inherited genetic disorders can also increase the risk of cataract formation. Cataracts can also be congenital, meaning they are present at birth. Congenital cataract is one of the leading causes of childhood blindness.
Diagnosis
Cataracts are diagnosed through a comprehensive eye examination conducted by an ophthalmologist. The exam may include the following tests:
- Visual Acuity Test: This is a standard eye chart test that measures how well you can see at various distances. It helps determine if your vision is blurred or reduced due to cataracts.
- Slit-Lamp Examination: This test uses a special microscope that illuminates the eye with a strong light, allowing the ophthalmologist to examine the front structures of the eye, including the cornea, iris, and lens, to detect any clouding or abnormalities.
- Dilated Eye Exam: The doctor may dilate your pupils using eye drops to help assess the extent of the cataract, and check for other eye conditions, such as retinal issues.
- Tonometry: Your doctor will usually measure the pressure inside your eye to assess for glaucoma, which can coexist with cataracts.
- Glare and Contrast Sensitivity Tests: These tests measure how your vision is affected by bright lights or glare and how well you can see objects in low contrast situations, which are common issues for people with cataracts.
Early diagnosis of cataracts is important to monitor the progression and determine the right time for surgery if needed.

Why is Cataract Surgery needed?
Here are some reasons why people need to undergo cataract surgery:
» You have reduced quality of vision or blurred vision affecting daily activities or driving.
» You have difficulty seeing well at night.
» You cannot see clearly even with glasses.
» Colors appearing faded.
» Sensitivity to glare and bright lights.
Types of Cataract Surgery
There are two main types of modern surgery procedures:
1. Phacoemulsification
The most common kind is called phacoemulsification, which involves carefully directing ultrasonic waves to break up the cloudy lens (cataract) into smaller pieces.
The ultrasound is delivered to the eye through a special hand-piece which fits into a self-sealing wound less than 2.5 millimetres wide. The ophthalmologist carefully removes the lens pieces with gentle vacuum.
Following lens removal, the ophthalmologist will insert a specially designed implant, known as an artificial intraocular lens (IOL). The IOL lens will be placed into the support structure where the natural lens used to be suspended at the front of the eye.
2. Femtosecond laser-assisted cataract surgery (FLACS)
In FLACS, a laser machine is used to perform some of the steps of cataract surgery including initial incisions, opening the lens capsule and dividing the lens.
Laser-assisted cataract surgery has not been shown to result in lower complication rates or better visual quality than in traditional phacoemulsification cataract surgery. The effectiveness of the FLACS technique is still being studied and researched, and its full potential has yet to be explored. However, there have been studies that have shown fairly equivalent outcomes.
FLACS may beneficial for advanced, mature cataracts, resulting in lower phacoemulsification energy.
Intraocular lens options
There are a variety of IOL lens options for focusing clearly after the cataract is removed. There are advantages and disadvantages of each type of lens.
Monofocal Lens
The most common type of lens inserted following cataract removal is a monofocal lens. This has a single focus. Monofocal lenses are usually selected for good distance focus, and the patient will then need to wear glasses for reading and near focus.
Toric Lens
Toric lenses provide correction for astigmatism, making vision clearer for those patients who have pre-existing astigmatism.
Extended depth-of-focus lens
Extended depth-of-focus (EDoF) lenses are specially designed to provide good distance and intermediate focus. This is helpful for using the computer, watching TV and seeing the car dashboard, for example.
Multifocal Lenses
These lenses split light to allow focusing at distance, intermediate and near focus. There is a compromise in the quality of vision and contrast that the lens provides. The optics of the lens design, which allows it to provide multiple focuses.
How to prepare for cataract surgery
» Explain the process of surgery, and the lens options.
» Take detailed measurements of your eyes to calculate the lens power.
» Order the appropriate lens for your eye(s).
Patients usually have to fast for a few hours before surgery, as light sedation is usually given. They may also need to stop taking certain medications, such as blood thinners.
It is a very safe and straightforward procedure in most cases, and patients usually go home shortly after. It is important to have someone bring you to the surgery centre or hospital, and take you home.
Here are a few things to know about surgery:
Anaesthesia:
For surgery on your eyes, the anaesthetist will numb the eye with drops, or an injection around the eye. You will also be given medication to help you relax. You’ll stay awake during the procedure, but the eye will be asleep. You may be able to see movement and some light. You will also hear the eye surgeon and the phacoemulsification machine. The procedure will not hurt, but you may feel some pressure while the surgeon is operating.
Positioning:
You will be lying down flat, or at a slight angle, for the cataract surgery.
Removal:
The ophthalmologist uses an operating microscope to perform the surgery. Tiny incisions are made to reach the lens, which is then broken up by ultrasound waves and surgically removed. Finally, the new artificial lens is placed and antibiotic injected to reduce the risk of post-operative infection.
The process of cataract surgery usually takes 10-15 minutes. In some cases, it can take longer. The admission process, anaesthesia and discharge means that you can be in the surgery centre or hospital for 2 or more hours.
The first night:
A pad and shield may be placed over the eye for the first night following surgery.
Eye drops
For about four weeks after the surgery, you will need to use prescription eye drops twice a day. These are anti-inflammatory drops to help the eye heal.
Most people need a few days for vision to improve after surgery. It is common for the eye to be red, gritty and irritated, and watery.
Most people will notice their vision improving after one week. The eye healing process takes about four weeks in most patients.
The days following surgery are crucial for a speedy recovery. Make sure that you follow all instructions given by your ophthalmologist, including:
» Using eye drops when you are instructed to.
» Wearing the plastic shield as instructed.
» Attending follow up appointments
These are things to avoid in the immediate days after cataract surgery:
» Do NOT rub your eye.
» Try not to get tap water or soap in the eye.
» Do not do strenuous activities.
» Avoid using eye makeup for one week.
» Do not drive or fly until your surgeon gives you the all-clear.
» Do not swim for four weeks after surgery.
Cataract surgery is very safe, however there are some risks with any medical procedure.
Blurred vision after cataract surgery
When you have cataract surgery, your eye may be blurry for a few days to a few weeks. It may take longer in some cases.
Most patients will update their glasses about 6 weeks after the cataract surgery is performed.
Cloudiness in the eye after cataract surgery “after-cataract”
Patients may feel a reduction in quality of vision months to years after routine cataract surgery. Some feel that their cataract has come back. Although a cataract cannot recur, a layer of scar tissue can form behind the artificial lens implant This is known as posterior capsule opacification (PCO), or “after-cataract”. PCO is a condition that can be treated very successfully by an office-based procedure known as a YAG laser posterior capsulotomy.
Floaters after cataract surgery
When you see floating shapes or specks of dust that follow your line of vision, it could be floaters in the vitreous. In most cases, floaters don’t require treatments, however they can be a sign of a retinal issue especially if associated with flashes of light.
Eye pain after cataract surgery
If you are experiencing severe eye pain, it may be because you have an infection or complications from the surgery such as high pressure. You should contact your surgeon as soon as possible.
Infection
An infection inside the eye (endophthalmitis) can be a devastating complication after routine cataract surgery. The risk is about 1 in 2000. Endophthalmitis requires urgent treatment with antibiotics and possibly even surgery. Some patients who are unlucky enough to develop endophthalmitis may lose vision completely.
Anaesthesia allergy
Although rare, it is possible to have an allergic reaction to anaesthesia. These reactions are often mild and should resolve quickly.
Do’s and don’ts after cataract surgery – general aftercare measures
» On the day of surgery, it is important not to drive.
» Resting at home for the first couple of nights is best.
» To avoid putting pressure on your eye, we recommend wearing a plastic eye shield throughout the night for one week following the surgery.
» There should be no contact to the eye with any water or other dirt for the first two to three weeks following surgery. During this time, the body can be washed from below the chin down.
» After cataract surgery, you need to instil the prescription eye drops in your eyes as advised.
» Avoid heavy weight lifting or excessive bending after the injury.
» Do not rub or touch the surface of your eye.
