本文通过对１９８６—１９９６年收治的眼内异物病例的临床分析，探讨手术术式的选择、手术时机及影响视力预后的因素。方法：对２４６例（２５８眼）眼内异物做回顾性的分析，并对两种术式（传统法及玻切法）的视力预后进行比较。结果：眼内异物取出率１００％，一次取出成功率传统法为７８．７％（５９／７５），玻切法为９９．５％（１８２／１８３），而玻切法术后视力增加和脱盲率均优于传统法。结论：玻璃体手术的应用有利于提高眼内异物摘出率，并可同时治疗伴有的严重并发症（牵引性网脱、ＰＶＲ等）或为视力改善创造条件
In this paper, clinical analysis of the cases of intraocular foreign bodies admitted in 1986-1996, to explore the choice of surgical procedures, timing of surgery and factors that affect the prognosis of vision. Methods: 246 cases (258 eyes) of intraocular foreign bodies were retrospectively analyzed, and the visual acuity prognosis of the two kinds of operation (traditional and vitrectomy) were compared. Results: The extraction rate of intraocular foreign body was 100%. The successful rate of one-time extraction was 78.7% (59/75) in traditional method and 99.5% (182/183) in vitrectomy. The visual acuity after vitrectomy and Blindness are better than the traditional method. Conclusion: The application of vitreous surgery is beneficial to improve the rate of extraction of intraocular foreign body and the simultaneous treatment of severe complications associated with it (tractive reticular detachment, PVR, etc.) or create conditions for improvement of visual acuity
