   Cataract surgery and IOL implantation have the safest and highest success rates of any eye care-related procedures. As with any type of surgery, however, some level of risk remains. [7] Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness. [92]
