The mortality from phakic intraocular lens placement is essentially zero. However there is the chance for morbidity, as with any surgery. The morbidity rate with IOLs, the rate at which at negative outcomes occur, is as high as 10 to 12 percent....

This rate varies based on the type of IOL lens used and the type of procedure performed. Since as many as one out of ten people will develop an unwanted side effect from phakic intraocular lens placement, it is important to discuss the risks of your specific procedure with your eye surgeon. Fortunately, unlike LASIK and related procedures, phakic IOL lens placement is reversible—if side effects occur the lens can simply be removed. Therefore most morbidity, if it occurs, can be treated.
