本组１７例（１８眼），其中磁性异物１４眼，非磁性异物４眼．经伤口修补、球内异物摘除、晶体囊外摘除及后房型人工晶体植入，裸眼视力＞０．５者为６６．７％，文中指出，皮质去除以冲洗为主，灌吸为辅，植入人工晶体时应使下襻与晶体下缘避开后囊破口，以防止后囊伤口扩大．本文并对人工晶体植入手法进行了讨论．术后５－氟脲嘧啶及激素球结膜下注射可抑制纤维母细胞增殖，预防人工晶体前膜形成，从而减少了术后并发症． The group of 17 cases (18 eyes), of which 14 were magnetic foreign bodies, 4 non-magnetic foreign body. After wound repair, intracranial foreign body removal, extracapsular lens extraction and posterior chamber intraocular lens implantation, uncorrected visual acuity> 0.5 was 66.7%, the paper pointed out that the cortex removal mainly flushing, irrigation supplemented, planting Into intraocular lens should be made under the 襻 and the lower edge of the crystal to avoid posterior capsule break, to prevent the expansion of the posterior capsule wound. This article also discusses the intraocular lens implantation practices. Postoperative 5-fluorouracil and hormone subconjunctival injection can inhibit the proliferation of fibroblasts, the prevention of intraocular lens anterior membrane formation, thereby reducing postoperative complications.
