Surgery is the only way to treat cataracts. There are no special eye drops or diets that can prevent or slow down cataracts once they start to form.
When should I have cataract surgery?
Cataract surgery is not urgent. If your sight is failing even though you wear glasses it means it is time to operate.
A patient should not wait until the cataract has become so thick that they cannot see. Surgery on a very advanced cataract is much harder and entails risks. How is cataract surgery performed?
Cataract surgery is a kind of micro-surgery carried out with the aid of a microscope. The eye is numbed with special drops before anesthesia or injections are given. During the operation a method known as "facoemulsification" or "faco" for short is used that melts away and extracts the part of the eye that has lost its transparency. It is replaced with an artificial lens (an intraocular lens). Since these operations are carried out through a hole measuring just 2.2 mm there is no need to apply stitches afterwards. The patient does not need to stay in hospital after the operation.
What should I do after the operation?
You can go back to your normal way of life after the operation. You must use the eye drops that are given in the prescribed manner. Water must not get into the eye for the first five days and we must protect our eye. You are free to watch TV, read a book or drive a vehicle.
