PK remained the primary surgical approach for repeat corneal transplants, while the proportion of EK showed an increasing trend (r = 0.520, P = 0.123; Fig. 1 ), and DALK showed a decreasing trend (r = −0.415, P = 0.233).

The number of regrafts had a hazard ratio of 1.559 in the univariate analysis, but this did not reach statistical significance ( P = 0.161).
