Patients requiring cataract surgery are managed with close attention to ensure that specific visual needs are met by surgical outcomes. Patient care is personalised and our eye specialists have access to the latest biometric and surgical technologies.
Cataract is a change in clarity of the natural lens inside the eye and occurs with normal aging. It is not an eye disease and usually does not require urgent attention in adults. Cataracts can be induced by trauma to the eye or by certain medications. Cataract formation usually occurs more rapidly in people with diabetes or those who smoke. Some babies are born with cataracts and these do require urgent attention by your eye specialist so that normal vision can develop in the child.
Cataract leads to hazy vision because light entering the eye is scattered before being focussed on the back of the eye (retina). Some people notice glare outdoors or difficulty driving at night. Some types of cataract can lead to a loss of detailed vision or a subtle change in colour vision. Most cataracts develop and progress slowly, allowing us to adapt to changes in vision. Glasses will not improve poor vision due to cataract since the loss of clarity is occurring inside the eye.
If cataracts are affecting your vision to an extent that you cannot see as clearly as you would like to, your eye specialist will offer cataract surgery. Your eye specialist might also recommend this surgery if your vision does not meet the driving standard or if there are other concerns with the health of the eyes that will be improved by cataract surgery. This surgery involves your eye specialist making a very small incision in the front of the eye so that your lens (cataract) can be removed and a new clear lens is then inserted in its place. Cataract surgery is performed on one eye at a time and eye drops are used for a couple of weeks after the surgery.
Your eye specialist will only recommend cataract surgery once they have confirmed that it will be of benefit to you. Part of this involves a thorough examination of all parts of the eye, taking into consideration other aspects of your eye health that might affect the outcomes from cataract surgery. In preparing for your surgery, your eye specialist takes into consideration your specific visual needs and surgical outcomes. Many people no longer require glasses to see clearly in the distance once they have had cataract surgery.
The developments in expertise and technology for cataract surgery mean that cataract surgery is now a short, low risk, minimally invasive surgery. Most cataract surgery involves a day procedure completed within less than 20 minutes. There are very low risks of infection and your eye specialist will discuss any specific risks with you before your surgery.
