Progressive astigmatism post-penetrating keratoplasty

A 40-year-old man, with a history of keratoconus and an ocular history of corneal transplants 15 years ago in both eyes, reported a gradual decline in visual acuity in the left eye over the course of the last several years, with increasing magnitude of cylinder in the refractive error. The patient is unable to wear rigid gas-permeable (RGP) contact lenses or scleral lenses, despite multiple trials over the years by numerous physicians. His corrected distance visual acuity (CDVA) was 20/20 and 20/60 in the right eye and left eye, respectively.
