Are there any risks of cataract surgery?

There are small risks associated with cataract surgery as with any operation. The risks can be divided broadly into two categories. Firstly, risks of the operation itself which can very rarely result in loss or reduction of vision which may not be correctable with glasses or contact lenses. There is also a risk of over correction in terms of the lens prescription and a very small risk of intolerance of the vision associated with a particular lens necessitating an exchange of that lens.
