Cataract
Cloudy vision and assessment of the progressive loss of transparency of the natural lens.
A cataract is a clouding of the crystalline lens, the natural lens inside the eye. It may make vision progressively blurred, cloudy or less bright.
A cataract is not a film on the surface of the eye. It is a loss of transparency of the natural lens.
How vision may change
Symptoms usually develop gradually and may include:
- blurred or less distinct vision;
- greater sensitivity to light and glare;
- haloes around lights;
- difficulty seeing at night;
- less vivid colours;
- frequent changes in spectacle prescription.
Diagnosis
The presence and impact of a cataract are assessed during an eye examination. It is important to establish whether reduced vision may also be related to another eye condition.
When surgery is considered
The decision depends not only on the presence of a cataract, but on how much it affects daily activities, independence and quality of vision.
When indicated, surgery removes the cloudy natural lens and replaces it with an intraocular lens. The choice of lens, visual target, alternatives and risks must be discussed individually after the necessary examinations.
Sudden loss of vision is not the usual progression of a cataract
Sudden loss of vision, flashes, new floaters, a dark curtain, severe pain, or a red eye with nausea require urgent medical attention.
Frequently asked questions
Does a cataract need surgery as soon as it is diagnosed?
Not always. The indication depends on visual symptoms, the person’s needs and the condition of the eye.
Is cloudy vision always caused by a cataract?
No. There are many other causes, some of which require prompt assessment.
Does surgery guarantee that I will no longer need glasses?
No. The need for glasses depends on the lens selected, the characteristics of the eye and the individual refractive outcome.
