Fig. 27. All sutures are gently pulled to remove excessive slack, and gentle traction on the distal sutures helps to guide the lens as insertion forceps are used to carefully place the leading haptic in the sulcus. The trailing or proximal haptic then is tucked under the iris with the assistance of tying forceps and a hook. The sutures then are secured. For the leading haptic, this is accomplished by cutting off the needles and tying the suture ends together, cutting the suture close to the knot, and burying the knot by rotating it into the sclera. The proximal suture, which is still attached to its needle, is pulled up, and a partial-thickness scleral bite is taken in the posterior bed of the incision. The suture is tied to itself and then trimmed. This knot is covered by sclera and thus effectively buried when the wound is closed in a watertight fashion with 10-0 nylon. |
