Corneal laceration may result from trauma which ranges from nonperforating trauma to full thickness lacerations (rupture globe) that may involve intraocular structures.
Management
In a nonperforating laceration, descemet's membrane perforation has to be ruled out. It is especially important to observe the integrity of the anterior chamber.
Bandage soft contact lens may be sufficient for a small self-sealing, beveled or edematous coneal laceration to protect the wound as it heals.
Cyanoacrylate tissue adhesive may be indicated for treatment of small perforating wounds with poor central apposition or stellate lacerations that do not self-seal along with bandage contact lens.
Full thickness lacerations (rupture globe) greater than 2-3 mm require suturing to structurally restore the globe's integrity.
General anesthesia is indicated particularly if the lacerations are large with possible expulsion of intraocular contents
Extensive lacerations with avulsion and large amount of tissue loss may eventually require lamellar or penetrating keratoplasty.
Peripheral iridotomy should be done in lacerations extending to the limbus to prevent the formation of anterior synechiae.
In corneal lacerations complicated with iris prolapsed, the iris viability should be evaluated for possible repositioning.
