A cataract is the clouding, or loss of transparency, of the natural lens of the eyes. If you have this condition, your vision becomes blurred or dim, because light cannot pass through the clouded lens to the back of the eyes.
- Long term use of steroid medication
- Eye injury/trauma
- Congenital condition (present at birth)
- Vision is cloudy and cannot be improved with prescribed spectacles or contact lenses
- Difficulty reading small prints
- Seeing multiple images
- Sensitive to bright light
- Poor night vision
- Reduction in colour intensity in vision
The consultant ophthalmologist will carry out a vision assessment and the following tests:
- Slit Lamp Examination (general diagnosis and referral to further diagnostic tests)
- Pupil Dilation (allows the consultant to assess the types and maturity of cataracts)
- It takes approximately 20 minutes for the pupil to be fully dilated
- After dilation, the patient’s vision will remain blur for 2-4 hours
- A scan / IOL Master of the eyes
- This will help the consultant select the type of artificial lens suitable for the patient
- Health Screening before surgery
- This may include blood tests for general health assessment and an electrocardiogram and chest X-ray for heart assessment.
Surgery is the only treatment for this condition. With the advancement of technology, there are various types of surgery, such as ultrasonic or laser, which breaks down the cataract and allows the surgeon to extract the clouded lens and replace it with an artificial lens, which are inserted into the eyes during surgery.
