My experience is with ribociclib (Kisqali). I contracted a bacterial infection in one eye leaving ulcers on my cornea. Almost exactly 6 months later, I had the same infection in the other eye leaving me legally blind with keratoconus. I did not fit any profile that would cause this other than the med so my ophthalmologist researched and came back with the comment that these drugs are "toxic to the eyes", his words. I wish my onco had been aware of the danger and warned me after the first infection but he said the drug manufacturer had no record of this situation.
