Spontaneous Long-Term Changes of Corneal Power and Astigmatism After Suture Removal After Penetrating Keratoplasty Using a Regression Model

In the follow-up after post-keratoplasty suture removal, patients with FD/KC tend to develop a spontaneous myopic shift (steepening of the cornea)/hyperopic shift (flattening of the cornea). In contrast with those with FD, patients with KC should be counseled on the fact that astigmatism may increase again over time after suture removal.
