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.
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.
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.
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.
描述一种通过白内障手术切口去除小于晶状体核四分之一大小的脱位核碎片的新方法。
连续 6 例患者的 6 只眼的视网膜表面脱位晶状体核碎片通过白内障手术切口进行了处理。将带有 27G 吊灯内照明器（双光灯照明）的前段玻璃体切割器插入眼中，并将其套管与另一个 27G 吊灯内照明器（双光灯照明）纤维的碎核器相连，用于抓取和移动较大的脱位核碎片进入前房，在那里将其分割并取出。
所有脱位的核碎片均通过白内障手术切口取出，且每位患者均植入了后房型人工晶状体，无重大并发症。
该方法可通过白内障手术切口从视网膜表面取出脱位的晶状体核碎片。与该方法相比，不需要进行需要三个端口的二次手术，也不需要玻璃体手术器械。
