Cataracts usually develop gradually as part of the ageing process, although they may also occur after eye injuries, certain medical conditions, or prolonged use of some medications. Early cataracts may not require surgery immediately, but regular eye examinations help monitor progression.
Age-related Cataracts
The most common type of cataract develops gradually over time as proteins within the natural lens begin to break down, leading to cloudy vision.
Congenital Cataracts
Some babies are born with cataracts or develop them during childhood. Early diagnosis is important to support normal visual development.
Traumatic Cataracts
Eye injuries can damage the natural lens and lead to cataract formation, sometimes immediately and sometimes years after the injury.
Secondary Cataracts
Certain medical conditions, previous eye surgery, radiation therapy, or long-term steroid use may increase the risk of developing cataracts.
Cataract Surgery
Modern cataract surgery is typically performed as a day procedure. The cloudy natural lens is removed and replaced with an artificial intraocular lens (IOL). Most people experience significant improvement in vision following recovery, although outcomes vary depending on individual eye health.
What's the Difference Between a Cataract Surgeon and an Ophthalmologist?
A cataract surgeon is an ophthalmologist who has expertise in performing cataract surgery.
An ophthalmologist is a medical doctor who diagnoses and treats a wide range of eye conditions, including cataracts, glaucoma, retinal diseases, diabetic eye disease, and macular degeneration. Many ophthalmologists perform cataract surgery, while others may focus on different subspecialties.
If you have cloudy vision or have been diagnosed with cataracts, an ophthalmologist with expertise in cataract surgery can assess whether surgery is appropriate and discuss the most suitable treatment options.
When Should You See a Cataract Surgeon?
You should consider consulting a cataract surgeon if you experience:
- Blurred or cloudy vision
- Increased glare from lights
- Difficulty driving at night
- Colours appearing faded
- Frequent changes in spectacle prescription
- Cataracts affecting daily activities such as reading or driving
An eye examination can determine whether cataracts are the cause of your symptoms and whether surgery is recommended.
