What is Cataract?
Cataract is the clouding of the normally clear lens of your eye. For people who have cataract, seeing through the cloudy lens is like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it difficult to read or drive (especially at night).
Cataract Signs and Symptoms:
- Clouded, blurred or dim vision
- Increasing difficulty with vision at night
- Sensitivity to light and glare
- Need brighter light for reading and other activities
- Seeing “halos” around lights
- Frequent changes in eyeglass or contact lens prescription
- Fading or yellowing of colours
- Double vision in a single eye
At first, the cloudiness in your vision caused by a cataract may affect only a small part of the eye’s lens and you may be unaware of any vision loss. As the cataract grows larger, it clouds more of your lens and distorts the light passing through the lens. This may lead to more noticeable symptoms.
- Cataract is treated only through surgery. There is no medication or eye drop which can treat cataract.
- Modern cataract surgery is a day surgical procedure which is done under local anaesthesia. The recovery of vision can be very quick.
- Phacoemulsification is current the gold standard for cataract surgery.
- This involves the use of high frequency ultrasound to break the cataract into little pieces which can then be removed through a very small wound (usually less than 3mm). No stitches are required.
- A clear artificial lens, also known as Intra Ocular Lens (IOL) is then placed into the eye.
