Cataracts develop as a normal part of the ageing process. By age 60, approximately half of all adults will have some cataract formation, although it may be minor and unnoticeable. By the age of 70, nearly everyone has some degree of cataract formation. However, not everyone with a cataract will end up needing cataract surgery.
Cataracts may also develop as a result of diabetes, various chronic eye diseases, eye injury or excessive UV light.
Cataracts are diagnosed by a professional examination that includes:
- An examination of the external and internal structures of your eyes.
- An assessment of your vision.
- Determining whether the cataract can be removed safely and successfully.
- Determining whether any other eye diseases are present and need treatment.
In some cases, pre-existing medical conditions may interfere with the successful outcome of cataract surgery. These include corneal scarring, glaucoma or macular degeneration. These will be detected and discussed at the time of your examination.
Every surgical procedure is associated with some risks and cataract surgery is no exception. While every attempt is made to minimise risks, complications can occur that may have permanent effects. We will discuss these with you during your eye examination and give you a brochure to read.
