Purpose:
To describe a novel technique to use the NGage® Nitinol Stone Extractor for large IOFB extraction.
Methods:
We conducted a retrospective case series study by reviewing the data of 4 eyes with retained large IOFB extracted with the use of the NGage® Nitinol Stone Extractor. The study was conducted in a single tertiary referral center on four eyes of four patients with large retained IOFB. Studied eyes were treated by pars plana vitrectomy (PPV) and IOFB extraction by using the NGage® Nitinol Stone Extractor through a limbal incision.
Results:
Four eyes of four male patients with large Retained IOFB were included in the study. The nature of the IOFB was metallic in 2 eyes, glass in 1 eye or ceramic 1 eye. All the IOFB were removed from a limbal wound. Silicone oil tamponade was required in 3 eyes. Two eyes required reoperation. At 6 months postoperative, the final visual acuity using Snellen chart ranged between PL and 0.1.
Conclusion:
The NGage® Nitinol Stone Extractor can be a useful tool for the extraction of the large retained IOFB.
