Contact information Denny: kjdenny1@aol.com analysis in the population selected; however, by excluding patients without perfect vision, the authors may have excluded the patients most likely to bring out the trends for which they were evaluating. In summary, these findings add that glistenings and surface light scatter develop in some hydropho- bic acrylic lenses and progress over time as far out as 9 years. Smaller glistenings may lead to greater sur- face scatter but the possible optical benefit of increased glistening size with greater IOL age may be over- shadowed by other factors such as increased density. Taken together, the current literature along with the addition of these articles gives some reassurance to clinicians that patients with otherwise excellent visual function who undergo im- plantation of hydrophobic PCIOLs are unlikely to develop marked dis- turbances of visual function due to the development of these lenticular optical imperfections during the first postoperative decade. The impact of glistenings and surface light scatter on patients with suboptimal vision and ocular comorbidities remains open for exploration. Larger and more inclusive studies are needed to rule out more subtle clinical effects and provide the final word on any visual significance of these lenticu- lar imperfections. Standardization of measurement parameters for glistenings and surface light scatter would also aid in the interpretation of future studies in order to assess whether the severity of these phe- nomena as assessed in a particular study corresponds to that observed in other studies and in clinical prac- tice.
