Abstract
To describe a novel technique for implantation of intraocular lens in the absence of capsular support using a ciliary sulcus guide. Based on the anatomic knowledge of the ciliary sulcus and the sclera, a new instrument was developed to pierce the needle safely through the ciliary sulcus and sclera. While the foldable lens is stored inside the cartridge, the leading haptic is sutured with a cow-hitch knot. The needle is then inserted into the ciliary sulcus guide. The tip of the guide is inserted from the corneal incision and proceeded under the iris to touch and fit the ciliary sulcus. The needle is pushed from back side. The needle comes out at precise point at the sclera. Implantation of the lens was performed through a 2.8 mm clear cornea incision using the injector. The trailing haptic is tied after implantation, and then the same procedure is performed at the opposite side. We performed this technique to 15 aphakic eyes without sufficient capsular support. There was no bleeding or other intraoperative complication. All the points coming out the sclera were between 2 and 2.5 mm from the limbus. The ab interno technique for scleral fixation of IOL is quicker, easier and less traumatic then ab externo techniques. A new ciliary sulcus guide which is usable with both straight and curved needles eliminates the blind maneuvers of ab interno technique and makes this technique more safe and precise.
