Abstract Details


To examine ocular injuries to eyes after keratoplasty and identify factors that affect visual outcome.


Department Of Ophthalmology, Dokkyo Medical University


We retrospectively analyzed the ocular injuries to 13 eyes of 13 patients, who had undergone keratoplasty as an inpatient procedure at Dokkyo Medical University between 2007 and 2013. Penetrating keratoplasty (PKP) using a trephine blade was performed in 12 eyes and deep anterior lamellar keratoplasty (DALK) in 1 eye.


Corneal graft dehiscence was found in all 12 PKP-treated eyes, regardless of history of ocular surgery, and was more common in the inferior region. Sclerocorneal wound dehiscence was found in the DALK-treated eye, which had a history of cataract surgery. Analysis of factors associated with visual outcome revealed that age at injury and presence/absence of a suture did not significantly affect visual outcome. However, post-injury visual acuity and area of corneal graft dehiscence were strongly correlated with postoperative visual acuity. Expulsion of the lens or an intraocular lens significantly affected visual outcome.


These findings suggest that a corneal perforating wound is considerably more fragile than a sclerocorneal perforating wound in the long term after keratoplasty. Evaluation of status and visual function immediately after ocular injury may help to predict the visual prognosis of ocular injury after keratoplasty.
