What are the risks of lens exchange surgery?

These are similar to cataract surgery. As with any surgery, there are small risks of the surgical procedure itself which include a number of factors that can result in reduction of visual function including quality of vision and loss of best corrected vision. The risks of this are low but if they do occur, then this may not be correctable with glasses or contact lenses. There is change of undercorrection or overcorrection of the focal length prescription possibly requiring an enhancement procedure in the months after the operation. A very small number of individuals find it difficult to tolerate the lens implant and require this to be removed or changed. Some individuals require a procedure called YAG laser capsulotomy in the months after the operation to clear the natural membrane behind the lens implant which often becomes cloudy naturally after an operation.
