Lisinopril leaves the body completely unchanged in the urine. [1] [16] The half-life of lisinopril is 12 hours, and is increased in people with kidney problems. [1] [16] While the plasma half-life of lisinopril has been estimated between 12 and 13 hours, the elimination half-life is much longer, at around 30 hours. [18]
One theory suggests that cyanopsia may develop due to the sudden unmasking of blue light sensitivity after cataract surgery, as the brain adjusts to the removal of the natural lens.

In many cases, only one eye is affected and the person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye.
