<unk>  <unk>  is a complication that may occur during cataract extraction in certain patients. This<unk>  is characterized by a flaccid<unk>  which billows in response to ordinary intraocular fluid currents, a propensity for this<unk> <unk>  to prolapse towards the area of cataract extraction during surgery, and progressive<unk>  pupil constriction despite standard procedures to prevent this.<unk>  has been associated with tamsulosin (e.g., Flomax), a medication widely prescribed for urinary symptoms associated with benign prostatic hyperplasia (BPH). Tamsulosin is a selective alpha blocker that works by relaxing the bladder and prostatic smooth muscle. As such, it also relaxes the<unk>  dilator muscle by binding to its postsynaptic nerve endings. Various alpha-blockers are associated with<unk> , but tamsulosin has a stronger association than the others. A joint statement of two ophthalmologic societies states that "the other major class of drugs to treat BPH — 5-alpha reductase inhibitors — do not appear to cause<unk>  to any significant degree." 5-ARIs include finasteride, a medication typically used as first line therapy for BPH and androgenic alopecia. The medication is also associated with cataract formation.<unk>  may also be associated with other causes of small pupil like synechiae, pseudoexfoliation and other medications (used for conditions such as glaucoma, diabetes and high blood pressure).<unk>  does not usually cause significant changes in postoperative outcomes. Patients may experience more pain, a longer recovery period, and less improvement in visual acuity than a patient with an uncomplicated cataract removal. The severity of the condition is not linked to the duration of tamsulosin intake.
