After carefully reading the article by Dr Hara and colleagues,1 I would offer the following comments and observations and encourage the authors to provide more information. It is still controversial whether the intraocular lens material affects the incidence of posterior capsular opacification.2-4 Nevertheless, information regarding the material of the intraocular lens implanted in the treated group was not provided. In addition, it is only stated, but not proved, that the posterior capsule does not touch the lens.
