Finasteride-associated cataract and intraoperative floppy-iris syndrome.

UNLABELLED

A 47-year-old man who had been using finasteride for male pattern alopecia for 4 years complained of progressive bilateral blurring of vision. His general health had been good, and he was not on any other long-term medication. Examination showed bilateral anterior subcapsular cataracts. Phacoemulsification and insertion of intraocular lenses were performed, and both eyes showed features of intraoperative floppy-iris syndrome (IFIS), including undulation and billowing of the iris, iris prolapse, and pupil constriction. We believe the use of finasteride can be associated with cataract formation and IFIS. Ophthalmologists and physicians prescribing finasteride should be aware of this possible association.
