<p>• Removing Cataracts</p> <p>Cataracts can be removed at any time. Due to modern equipment, there is no reason to wait for the cataract to become ‘ripe’ before removal. Most people choose to remove their cataracts when it starts to affect their vision and cause difficulties in everyday life. This varies from person to person and should be discussed with your eye specialist who will provide further advice.</p> <p>• What to expect before Surgery?</p> <p>Before removing the cataract, you will be required to have a pre-operative eye examination to decide the details of surgery. Your vision will be checked and the eye measured to decide the strength of the lens that is to be implanted when the surgery is performed. If you have had previous eye surgery / laser procedures, you must inform your Ophthalmologist.</p> <p>• The Surgery</p> <p>Cataract surgery usually lasts about 10-12 minutes. It is usually done with a local anaesthetic, which means you will be awake throughout the procedure but will feel no pain. However, it can be done under general anaesthetic, meaning you will be completely uncoinscious during the surgery. You will be given dilating drops to the eye to be operated on. Your face will be covered by a sheet in order to keep the area around your eye clean during the surgery. The most common way to remove cataracts is phacoemulsification. This involves using high frequency sound energy to breakup the natural lens with the cataract. Only small incisions are used, eliminating the need for stitches. The eye surgeon generally uses a microscope to get the best view of your eye. During the operation, the surgeon cuts through the lens capsule and removes the clouded lens using suction. The lens capsule is left in place and an artificial lens is implanted in place. If you are awake for the surgery, it is important that you keep as still as you can.</p> <p>• What to expect after the Surgery?</p> <p>After surgery, your eye will be covered with an eye shield and dressing. As the anaesthetic begins to wear off, it is normal for the eye to feel a bit sore. This pain is usually not too bad and painkillers such as paracetamol can be used to help. If your cataract was relatively mild, you may not detect a big change in vision but if your cataract was quite bad you may notice quite an enhancement in your vision. Nonetheless, your sight may not be as good as you expect for the first week after surgery as the eye may still be recovering. You will be given eye drops to reduce inflammation and it is important that you use it as advised. Most people have no problems and are up and about as normal the next day. You may however find certain lighting too bright for a couple weeks and wearing sunglasses can assist with this. If any problems arise, please inform your doctor.</p>
