Cataracts are the commonest cause of reversible vision loss
9 in 10 Australians develop cataracts by the age of 65.
What is a Cataract?
A cataract is a clouding of the normally clear lens inside the eye. Most cataracts occur slowly over many years as part of the natural ageing process.
As a cataract advances and matures, it may result in blurry vision, glare, dulling of colours, frequent change of the prescription of your glasses, and difficulty driving at night.
In the early stages, stronger lighting and glasses may improve the symptoms from cataracts. However, the only definitive treatment for cataracts is through cataract surgery to remove the cloudy lens and replace it with a new artificial lens. This operation is usually a safe, effective and painless day procedure performed by an ophthalmologist.
How are cataracts removed?
The most common surgical technique to remove cataract is phacolemulsifcation.
The operation is performed under local anaesthetic.
By viewing the patient’s eye through a high-powered microscope, Dr Fan Gaskin makes a very small incision (approximately 2.5 mm) on the edge of the cornea. A small ultrasonic probe is inserted to divide the cloudy lens into tiny pieces. The pieces are then gently suctioned away out of the eye through the same probe.
An artificial intraocular lens is then implanted into the same position as the patient’s own lens as a replacement. Rarely the intraocular lens may need to be placed in an alternative position.
As the incision is so small, stitches are rarely required. After surgery, the eye is covered for protection for a few hours. The operation usually takes approximately 20 minutes.
How successful is cataract surgery?
In a healthy eye, the success of cataract surgery is 98%. The risk of serious complications is extremely low.
How quickly will I recover after cataract surgery?
Recovery is usually quick. Most patients notice a dramatic improvement the following morning after surgery once the shield is removed. In the first few days the patient experience more light sensitivity and Dr Fan Gaskin may ask you to refrain from certain activities such as swimming and heavy lifting for 1-2 weeks. Eye drops are usually required for 3-4 weeks following surgery to prevent infection and inflammation. You will also be reviewed by Dr Fan Gaskin during the recovery period.
Will I need glasses after surgery?
Most patients achieve good vision after cataract surgery. Glasses may be require to refine the patient’s vision for certain distances. As each patient will have their own individual visual requirements, Dr Fan Gaskin will discuss with each patient the choices available to allow them to achieve their desired visual outcome.
