A histomorphological study on the effect of iridocapsular intraocular lens on the iris. A case report.

A Binkhorst iridocapsular intraocular lens was implanted into an eye of a patient after an extracapsular cataract extraction. The patient died 4 months after surgery of gastric cancer. The eye was obtained for histopathologic examination at the autopsy. The superior loop was inside the residual capsular bag causing no damage to the iris and ciliary body. The inferior loop, however, was found outside the capsular sac and caused depression of the iris tissue but neither inflammation nor scarring of the iris had developed. These findings emphasize the importance of the location of iridocapsular intraocular lenses which can cause mechanical damage to the supporting tissues if the loops are not placed inside the capsular bag.
