摘　　要：目的探讨改良角膜异物取出术治疗非穿透性角膜异物的效果。方法回顾性病例系列研究。纳入丽水市人民医院2021年1月至2023年1月收治的非穿透性角膜异物患者108例。根据治疗方式不同分为两组,每组各54例。对照组采用常规角膜异物取出手术,改良组应用改良弯针取出角膜异物。比较两组角膜异物一次性剔除率、异物残留率、角膜损伤范围<0.1 mm比例、随访7 d内继发性角膜感染发生率、角膜异物剔除时长、角膜上皮愈合时间,分析视力的影响因素。结果治疗后改良组角膜损伤范围<0.1 mm者14例(25.93%,14/54),异物残留者1例(1.85%,1/54)且随访期无继发性角膜感染发生;对照组角膜损伤范围<0.1 mm者29例(53.70%,29/54)、异物残留角膜12例(22.22%,12/54)、继发性角膜感染者4例(7.41%,4/54),两组相比差异均有统计学意义(χ^(2)=8.69、10.58、4.15,P=0.003、0.001,0.042)。角膜异物一次性剔除率(98.15%,53/54)明显高于对照组(75.93%,41/54)(χ^(2)=11.82,P=0.001);改良组角膜异物剔除时长[(1.41±0.32)min]及角膜上皮愈合时间[(1.32±0.21)min]均显著短于对照组[(2.23±0.46)、(2.11±0.35)min](t=10.75、14.22,均P<0.001);且经单因素分析年龄、职业、受伤环境、入院视力、并发症等因素与治疗后患者视力有关(χ^(2)=6.09、11.89、7.36、5.57、9.27,P=0.048、0.003、0.025、0.018、0.002)。结论非穿透性角膜异物患者采用改良角膜异物取出术,可有效缩短异物剔除时间,降低角膜感染发生率。ObjectiveTo evaluate the efficacy of modified corneal foreign body extraction in the treatment of non-penetrating corneal foreign bodies.MethodsThis was a retrospective case series study.A total of 108 patients with non-penetrating corneal foreign bodies in Lishui People’s Hospital from Jan.2021 to Jan.2023 were included.They were divided into two groups based on different treatment methods,with 54 cases in each group.The control group was treated with conventional corneal foreign body extraction,and the modified group was treated with modified corneal foreign body extraction.The one-time removal rate of corneal foreign body,the residual rate of foreign body,the probability of corneal injury range<0.1 mm,the incidence of secondary corneal infection,the duration of corneal foreign body removal and the healing time of corneal epithelium within 7 days of follow-up were compared between the two groups,and the influencing factors of visual acuity were analyzed.ResultsAfter treatment,there were 14 cases with corneal injury range<0.1 mm(25.93%,14/54),1 case with foreign body residue rate(1.85%,1/54)and no cases with secondary corneal infection in the modified group,which were significantly lower than the(53.70%,29/54),(22.22%,12/54)and(7.41%,4/54)in the control group,respectively(χ^(2)=8.69,10.58,4.15;P=0.003,0.001,0.042).After treatment,the rate of one-time foreign body removal(98.15%,53/54)was significantly higher than that of the control group[(75.93%,41/54)](χ^(2)=11.82,P=0.001);the foreign body removal time[(1.41±0.32)min]and corneal epithelial healing time[(1.32±0.21)min]in the modified group were significantly shorter than those in the control group[(2.23±0.46)min and(2.11±0.35)min(t=10.75,14.22;P<0.001,P<0.001)].By univariate analysis,age,occupation,injury environment,admission vision,complications and other factors were related to the visual outcome of patients(χ^(2)=6.09,11.89,7.36,5.57,9.27;P=0.048、0.003,0.025,0.018,0.002).ConclusionModified corneal foreign body removal in patients with non-penetra
