Eighteen eyes with wound dehiscence after penetrating keratoplasty were studied. Keratoplasty was performed for corneal scarring (n = 8), dystrophies (n = 6), graft failure (n = 2), and corneal edema (n = 2). The mean duration between keratoplasty and wound dehiscence was 6.54 months. All eyes underwent wound repair with or without iris excision, lensectomy, and vitrectomy. Grafts remained clear in eight eyes. Five eyes developed phthisis bulbi. Visual acuity was better than 20/200 in seven eyes. There was no site (quadrant) specificity for dehiscence. Trivial trauma resulted in dehiscence in 10 of the 18 eyes. The major determinants of visual outcome were the force of trauma and status of the posterior segment. Dehiscence of the graft-host junction in all cases reflects its persistent weakness after surgery.

UI	MeSH Term	Description	Entries
D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.
D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens

D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
