Dear LHig,
You bring up some good questions regarding your corneal surface. You now have three diseases, conjunctivochalasis, keratoconus and Cogan’s corneal dystrophy. I would recommend that you seek the care of an additional corneal specialist or speak to the one you saw, to determine whether other options may help. As I am not familiar with your entire course, it is difficult to assess whether medications may be causative. Of course, discontinuation of the medications should help the surface, if they are the cause.
