CATARACT SURGERY
WHAT IS A CATARACT?
A cataract is the opacification, or clouding, of the natural lens in the eye. It is the leading cause of blindness in the world. The eye's natural lens is a clear, flexible structure which focuses light onto the retina. This enables us to see objects clearly and at varying distances. The lens is located in the eye, behind the iris (the coloured part of the eye).
Cataract formation is usually due to aging and can cause vision loss. With age, fluid-filled bubbles and clefts form between the lens fibers, degenerating fibers accumulate in the clefts, and the lens fibers darken. Over time, the clumps get bigger and thicker and clouding of the lens occurs. The lens also becomes less flexible, making it difficult for the eye to focus light properly. This leads to vision problems.
Although most cataracts are related to aging, cataracts can also be congenital, secondary to other health conditions (such as diabetes) or caused by trauma to the eye/s.
Cataracts can be removed surgically with excellent results.
FREQUENTLY ASKED QUESTIONS:
What Symptoms Are Associated With Cataracts?
The most common cataract symptom is cloudy or blurred vision - as if you’re looking through a dirty windshield or a frosted window.
Other vision changes may include:
Double-vision or ghosting of images.
Difficulty reading small print and driving at night.
Reduced night vison and difficulty seeing when in poorly lit areas.
Experiencing glare and seeing ‘halos’ around lights.
Seeing bright colours as faded, dim or yellow.
More frequent changes to your glasses or contact lens prescription.
How Do We Treat a Cataract?
Cataract treatment typically involves surgically removing the cloudy lens and replacing it with an artificial lens called an intraocular lens (IOL). The surgery is usually performed on an outpatient basis and typically takes less than an hour. The surgery is typically done under local anesthesia, usually with some form of conscious sedation, so you are partially awake but don't feel any pain. After the surgery, you will need to wear an eye patch or shield and use eye drops for several weeks. Most people can return to their normal activities within a few days after the surgery.
When Is It Necessary to Operate a Cataract?
Many years ago, when cataract surgery was a fairly new procedure, the preferred treatment protocol was to operate cataracts only once they had matured, or 'ripened'. This was because the procedure was often associated with various complications.
Modern cataract surgery is associated with much lower complication rates and outcomes are far more predictable. As such, is it preferred to operate cataracts when they become symptomatic, especially when they begin to negatively affect a patient's quality of life.
If you have a cataract and are struggling with your vision, you may be a good candidate for cataract surgery.
Is Cataract Surgery Safe?
Yes, cataract surgery is a safe and effective procedure. It is one of the most commonly performed surgeries in the world and has a high success rate. The procedure is usually performed on an outpatient basis, and most patients experience improved vision after the surgery.
Is Cataract Surgery Painful?
Cataract surgery is usually not painful. Most patients report feeling no pain during the procedure. Some patients may experience a slight pressure sensation during the procedure, but this is usually not uncomfortable.
Don't let cataracts hold you back from enjoying life to the fullest!
