What are the risks of having a cataract operation?
There is a small risk in having any operation. This is also true for a cataract operation. In the hands of an experienced surgeon the risk of ending up with worse vision as a result of the surgery is small; perhaps of the order of 1% or less. The risk of losing all vision or of requiring removal of the eye after the operation (e.g. because of an infection) is extremely remote; but it is not zero. The types of risk involved in having a cataract operation include: Infection within the eye. Bleeding within the eye.
