Immediate removal of posteriorly dislocated lens fragments through sclerocorneal incision during cataract surgery

摘要

Aim: To describe a new method of removing dislocated nuclear fragments smaller than one-fourth the size of the lens nucleus through the sclerocorneal incision made for cataract surgery. Methods: Dislocated lens nuclear fragments on the surface of the retina were removed from six eyes of six consecutive patients. An anterior vitreous cutter with a 27-gauge chandelier endoilluminator (Twinlight illumination) tied to its sleeve was inserted into the eye through the incision made for cataract surgery and used for core vitrectomy. A fragmatome with another 27-gauge chandelier endoilluminator (Twinlight illumination) fibre was used to grasp and move the larger dislocated nuclear fragments into the anterior chamber where they were divided and removed. Results: All dislocated nuclear fragments were removed through the incision for cataract surgery, and a posterior chamber lens was implanted in each patient without major complications. Conclusions: The procedure can be used to remove dislocated lens nuclear fragments from the surface of the retina through the incision for cataract surgery. Neither a second surgery, which would require three ports, nor the body of instruments for vitreal surgery are needed with this procedure.
