Validity of ISO eye model.

important to make this distinction because over time, there will be more and more patients with age-related cataract. This distinction will prevent any misunderstanding in this area. A study performed in 10 years will probably show disastrous, incorrect, results. We feel this is a serious omission, especially because it is the essence of the article. As an example, an article by Tahzib et al., of which I am a coauthor, reports 2 eyes that had explantation of the Artisan pIOL and subsequently required phacoemulsification and implantationof aposterior chamber IOL due to an age-related cataract that developed 6 years postoperatively. The article was reviewed by Chen et al. (see reference 185), and I am sure there will be several similar cases.
