Cataract is the clouding of the natural clear lens in the eye (the crystalline lens).
Cataract is a natural part of aging, but in some individuals it may occur at a younger age due to trauma (example, being hit on the eye) or a side effect from certain medications.
Mild cataract may not affect the clarity of vision, but as it matures, it can cause:
- blur vision
- sensitive to light
- double vision in one eye
- yellowing or fading of colours
- reading difficulty
- poor night vision
- glare and haloes
Cataract is treated via a modern surgical procedure known as phacoemulsification (phaco).
In phaco, an artificial lens (also called an Intra Ocular Lens (IOL)) is used to replace the cloudy natural lens in the eye. The Intra Ocular Lens can be custom made to suit the individual’s eye power.
