Abstract：
OBJECTIVE: To show an alternative surgical technique for the introduction of the intravitreal fluocinolone acetonide (FAc) implant (Iluvien®) into the vitreous cavity using a 23-gauge (G) trocar if it is retained during its implantation in the subconjunctival space.
METHODS: We describe the surgical procedure performed to solve the complication: The FAc implant was extracted from the subconjunctival space using flat retinal forceps. A 23-G trocar was inserted 3,5 mm to the limbus. The same flat retinal forceps were used to take the FAc implant and introduce it into the vitreous cavity using a 23-G trocar.
RESULTS: The patient\'s best corrected visual acuity (BCVA) (Snellen) improved from 20/200 to 20/63 and the central macular thickness (CMT) was reduced from 610 microns (µm) to 215 µm after one week of the FAc implantation. He remained stable after 3 months of follow-up, with a BCVA of 20/63 and a CMT of 191 µm. His intraocular pressure (IOP) remained stable and the integrity of the implant was checked by indirect ophthalmoscopy.
CONCLUSIONS: The introduction of the intravitreal FAc implant using a 23-gauge trocar constitutes a valid alternative if it is retained during its implantation in the subconjunctival space.The functionality of the implant remained intact in our patient.

摘要：
目的：显示一种替代的手术技术，用于使用23号（G）套管针将玻璃体内的氟轻松（FAc）植入物（Iluvien®）引入玻璃体腔，如果其在结膜下空间的植入过程中保留。
方法：我们描述了为解决并发症而进行的外科手术：使用扁平视网膜镊子从结膜下间隙中提取FAc植入物。将23-G套管针插入到角膜缘3.5mm处。使用相同的扁平视网膜镊子取出FAc植入物并使用23-G套管针将其引入玻璃体腔。
结果：患者的最佳矫正视力（BCVA）（Snellen）从20/200提高到20/63，黄斑中心厚度（CMT）从610微米（µm）降低到215µm。他在3个月的随访后保持稳定，BCVA为20/63，CMT为191µm。他的眼内压（IOP）保持稳定，并通过间接检眼镜检查植入物的完整性。
结论：如果在结膜下空间的植入过程中保留了使用23号套管针的玻璃体内FAc植入物，则是一种有效的替代方法。植入物的功能在我们的患者中保持完整。
