眼外伤后行二期悬吊人工晶状体植入46例临床分析

Outcomes of secondary implantation of suspension intraocular lens after ocular trauma

目的探讨46例（46只眼）眼外伤后行二期悬吊人工晶状体植入术的手术技巧和临床疗效。方法选取我科2010年9月至2011年12月46例（46只眼）因眼外伤后未能一期植人人工晶状体行二期悬吊人工晶状体植入术患者的临床资料进行回顾性分析。根据病情选择悬吊式人工晶状体或虹膜型人工晶状体植入并观察术后人工晶状体位置、最佳矫正视力、眼压、角膜、眼底及并发症情况。结果随访3～6个月，平均5．4个月，最佳矫正视力≥0．5者8只眼（17．39％），0．3-0．5者26只眼（56．52％），0．1-0．3者10只眼（21．74％），0．05-0．1者2只眼（4．35％）。手术前后最佳矫正视力比较具有统计学意义（t=27．71，P〈0．00）。结论对于眼外伤后未能一期行人工晶状体植入的患者，通过术前视力矫正能提高的患者行二期悬吊人工晶状体植入术是提高患者视力的理想方法。

Objective To investigate the surgical skills and efficacy of secondary implantation of suspension intraocular lens in 46 patients （46 eyes ） with ocular trauma. Methods Subjects of this study were 46 patients who were unable to receive primary intraocular lens （IOL） implantation after trauma. Patients received secondary intraocular lens implantation with either suspension lens or iris supported lens. Position of the IOL, the best corrected visual acuity, intraocular pressure （IOP） 0 cornea, fundus and complications were reviewed and compared between the groups. Results With a median follow-up of 5.4 months （ range 3 - 6 months ）, best corrected visual acuity was better than 0. 5 in 8 eyes （ 17. 39% ）, 0. 3 - 0.5 in 26 eyes （ 56.52% ）, 0. 1 - 0.3 in 10 eyes （ 21.74% ）, and worse than 0.1 in 2 eye （ 4.35% ）. Generally the best corrected visual acuity significantly improved after the treatment （ t = 27.71, P 〈0.01 ）. Conclusion For patients with ocular trauma who are not good candidates for primary intraecular lens implantation, secondary IOL implantation with suspension lens could be an desired option because it provides satisfactory vision recovery.
