Size of PK as one of the parameters with an increase in diameter from (a) to (c), location of the PK as a varying parameter where the location is (d) towards one of the horizontal periphery, (e) towards one of the vertical periphery, and (f) towards one of the diagonal periphery, suture tension as on of the varying parameter where black lines across donor-host junction represent uniform tension sutures, blues represents loose sutures, and red represents tight sutures where the scenarios (g) PK with few loose sutures, (h) PK with few tight sutures, and (i) PK with combinations of loose, tight, and uniform sutures.
