Fig. 5. Effects of suture placement for corneal lacerations. A. For sharp perpendicular wounds, deep suture placement equidistant from the wound margins gives excellent wound approximation. B. Shallow sutures create internal wound gape. C. Full-thickness sutures may create a conduit for microbial invasion. D. Sutures of unequal depth create wound override. E. Sutures of unequal length create wound override. F. For shelved lacerations, sutures should be placed equidistant with respect to the internal aspect of the wound to achieve good wound apposition.
