Contact information Pyatetsky: d-pyatetsky@northwestern.edu design, a significant concern is the small number of patients who actu- ally had a complication at all. The study is not powered to detect small changes between the 2 groups when the absolute number of complica- tions (from the small sample size) is this low, and therefore type II error to accept the null hypothesis is un- acceptably high. This may have only been recognizable in the post hoc analysis by the authors, who may have suspected a higher number of complications, but should be ac- knowledged as the major limitation of the study and need for further investigating. In summary, this is a valuable study bringing attention to a novel surgical technique for managing aphakia. Given the challenges of tra- ditional sutured SFIOL insertion, it is encouraging to see that less skill-in- tensive techniques are becoming available to surgeons. A properly constructed randomized control comparison with sufficient power and long-term follow-up is needed to determine if sutured and suture- less SFIOL insertion are equivalent in terms of efficacy and safety. How- ever, these trials cost money and time, and in the absence of them, studies such as these are invaluable as they provide guidance for surgi- cal decision-making in challenging situations.
