• Positive vitreous pressure during penetrating keratoplasty can be difficult to manage. Despite preventive measures, positive vitreous pressure may occur and appropriate intervention is necessary to prevent serious complications. We describe a technique that may be used intraoperatively to restore a formed anterior segment and to prevent vitreous loss when persistent positive vitreous pressure occurs, while attempting to implant a pseudophakos. A 27-gauge needle, passed across the anterior chamber from limbus to limbus, just anterior to the iris, will stabilize the pseudophakos, restore the anterior chamber depth, and allow donor-tissue suturing.
