Cataracts are an extremely common kind of eye disorder characterised by clouding on the eye lens. It can either occur in one or both eyes. In cases where it affects both eyes, the impact is more severe in one eye than the other.
Sometimes people may not even realise that they have cataracts. Many cataracts are not substantial enough to require any treatment. However, the only effective discourse for cataracts is surgery. Surgery may not be needed in patients who suffer only mild symptoms of the disorder.
The optometrist will recommend treatment for your cataracts depending on the extent to which your vision loss is affecting your daily activities. For example, treatment may be recommended if your cataract(s) affect:
The above mentioned approaches are only temporary solutions. In spite of taking measures, the cataracts will continue to develop and gradually impair your eyesight for worse, eventually leading to a need for surgery.
The specialist will recommend surgery if the patient:
The most common cataract operation is called phacoemulsification, which is sometimes referred to as phaco extracapsular extraction. Cataracts can't be treated with laser surgery (when beams of energy are used).
Catarct surgery involves removing the cloudy lens in your eye. It is done through replacing the natural eye lens with an artificial, clear plastic lens. This procedure is known as an intraocular implant or intraocular lens (IOL).
Before the operation, your eye will be measured in order to prepare the artificial lens which will replace your natural eye lens. Your overall health is also assessed.
Just before you are taken for the surgery, eye drops to dilate (widen) your pupil (the black circle in the middle of your eye) will be put into your eye. The surgeons will also give you a local anaesthesia to prevent you from feeling any pain during the procedure.
The ophthalmologist will make a small incision in the cornea of your eye, inserting a tiny probe through this cut. The probe breaks up the cloudy lens into tiny pieces using ultrasound (high-frequency sound waves). The tiny pieces will then be sucked out of your eye.
After that, the doctor will insert an artificial lens through the incision. The operation usually takes 15-30 minutes.
Your ophthalmologist will probably advise you to take it easy, for example, by:
When the cataracts are age-related, two other operations may be performed to remove them. They are- manual extracapsular extraction, and intracapsular extraction. In case you are experiencing a cloudy vision lately, consult your eye doctor immediately for diagnosis. Your vision may be at risk.
