[Analysis of penetrating corneal regrafting in 29 cases].

Repeated penetrating keratoplasty was retrospectively analyzed in 29 cases followed up 1-4 years postoperatively. The regraft remained clear in 10 eyes (34.5%). The major causes of regrafting failure were similar to those of the initial keratoplasty, i.e. immunologic rejection, postoperative angle-closure glaucoma, and donor graft failure.
