Cataract surgery is one of the most commonly performed surgeries in Australia.
A cataract is a clouding of the natural crystalline lens in the eye. It causes symptoms such as blurred vision, increased glare sensitivity, reduced brightness and colour perception, and difficulties driving at night.
Cataracts most commonly occur in the over-50s due to natural age-related changes in the eye. Age-related cataracts usually develop slowly.
Sometimes, cataracts can form at birth (congenital cataract) or develop after trauma or medication use (steroids).
Currently, cataract surgery is the only proven way to treat a cataract.
When your ability to perform daily activities like reading and driving becomes significantly impacted by cataracts, your ophthalmologist may recommend cataract surgery to improve your vision.
What is involved in Cataract Surgery?
During cataract surgery, patients are placed under sedation and the eye is numbed with local anaesthesia. A small, micro-incision is made on the surface of the eye and the cloudy crystalline lens is broken up using a small ultrasound device. This process is known as phacoemulsification. The fragmented crystalline lens is then removed under microscopic guidance and a new artificial intraocular lens, known as an IOL, is inserted into the eye. IOLs are biocompatible (meaning your body should not reject the IOL) and do not usually need to be replaced or changed in your lifetime.
Cataract surgery usually takes less than 30 minutes and most patients can go home the same day with a clear eye shield over the eye. Postoperative eye drops (antibiotics, anti-inflammatory drops and lubricating drops) are used for a few weeks after surgery. Most people are aware that their vision is brighter and “more white” immediately after surgery. Over the next few days, vision should continue to improve. The eye itself is usually comfortable, and most patients report only mild discomfort or grittiness.
You cannot drive for 24 hours (to allow the sedation to clear your system), however most other normal activities can be resumed immediately after surgery. Your specialist will probably recommend avoiding strenuous activities (such as heavy lifting), gardening and swimming for two weeks.
