“…ese techniques either require special instrumentation with limited access to most ophthalmologists or very traumatic with a high risk of intraoperative and postoperative complications. ere is a simple but elegant design of IOFB lasso [15] or snare [16], with the limitation of monoplane holding force, which is insufficient in spherical or olive-shaped IOFB.…”

Purpose. To report a novel technique of cross-knotted suture basket and to test its effectiveness in large nonmagnetic intraocular foreign body (IOFB) removal. Methods. A 7/0 Vicryl suture was cut in half and cross-knotted, and four ends were introduced into a 23G needle to form a basket. Pig eyes were used to set up the IOFB model, and the effectiveness of the suture basket in the removal of large nonmagnetic intraocular foreign bodies was tested. Results. Several modifications can be made to adapt to different situations. For the materials (stone, metal, glass, and wood) and shapes (irregular, spherical, and rectangle) of large IOFB tested, the cross-knotted suture basket successfully removed all kinds of IOFBs. Conclusion. The suture basket technique provides an accessible, safe, and effective alternative in large nonmagnetic IOFB removal. It can be adapted and interchangedand also worth’s further clinical investigations.

“…2 The instrument was modified by Chronopoulos et al 4 who used a flute needle and syringe to manipulate and tighten the snare and by Acar et al 5 who also suggested a bimanual technique to introduce the foreign material into the snare. Similarly, a commercially available memory snare IOFB extractor was developed by Eckardt et al 6 with the advantage of an angled loop which can grasp the material without the need to pass beneath the foreign body.…”

To report and demonstrate removal of an intraocular metallic spherical pellet and to describe the construction of a basket instrument.Methods: A 9-year-old boy sustained a pellet gun injury and underwent pars plana vitrectomy to remove an intraocular spherical metallic pellet. A suture loop basket constructed with 3-O nylon and 16-gauge intravenous cannula was used to grasp and remove the foreign body.Results: The pellet was mobilized from a subretinal position and effectively captured in the basket using the light pipe as a second instrument. The captured pellet was successfully removed without slippage via a scleral tunnel incision. Despite reattachment of the retina under silicone oil, the vision deteriorated to no light perception.Conclusion: A simple, readily available basket can be constructed for the effective removal of spherical foreign bodies which are difficult to grasp.

“…This would reduce the risk of iatrogenic trauma that may result from droppage during extraction through a sclerotomy 15 . Several tools have been developed, including simple forceps, diamond tipped forceps, 15 lassos, 16 snares, 17 , 18 and aspiration/suction cannulas 19 …”

Purpose Glass intraocular foreign bodies (IOFBs) complicate up to 14% of all IOFB cases and require specialized instruments for removal. We present a case of ocular trauma with two large glass IOFBs removed using a nitinol stone basket (NSB) designed for kidney stone extraction in the ureter and calyces. Observations An adult male suffered a restrained motor vehicle accident. Radiographic computed tomography identified a 9-mm polygonal IOFB within the posterior segment of the right eye. A staged procedure was performed with repair of the ruptured globe followed by 23-gauge pars plana vitrectomy, pars plana lensectomy, and removal of the IOFBs using a NSB. Conclusion At post-operative month one, visual acuity was correctable to 20/60. The retina remained attached and the patient was recovering without complication. Importance Large glass IOFBs are poorly gripped by standard ophthalmic forceps due to their smooth surface, large size, and irregular shape. The NSB is an effective instrument for controlled removal of glass IOFBs. Further customized design may adapt this device for additional intraocular procedures.
