目的探讨小切口非超声乳化囊袋内植入人工晶状体治疗晶状体半脱位的可行性、技术特点和注意事项。方法对56例(58只眼)白内障合并晶状体半脱位(悬韧带断裂≤120°)患者,实行小切口非超声乳化白内障囊外摘除,术中环形撕囊,植入人工晶状体入囊袋内。结果58只眼有56只眼人工晶状体植入囊袋内,人工晶状体稳定、居中;2只眼因晶状体脱位处囊膜缺失,行人工晶状体单袢缝合术。术后视力均有较大提高,无严重并发症。结论对于晶状体脱位≤120°的白内障患者,小切口非超声乳化囊袋内植入人工晶状体是可行的、安全的。
Objective To investigate the feasibility, technical characteristics and precautions of intraocular lens implantation for intraocular lens implantation in small incision non-phacoemulsification capsular bags. Methods 56 patients (58 eyes) with cataract combined subluxation of the lens (suspensory ligament rupture ≤120 °) were treated with small incision non - phacoemulsification extracapsular cataract extraction, intraoperative capsulorhexis and intraocular lens implantation in the capsular bag. Results Fifty-eight eyes (56 eyes) were implanted in the capsular bag. The intraocular lens was stable and centered. The capsular membrane was missing in the two eyes due to dislocation of the lens. Postoperative visual acuity have been greatly improved, no serious complications. Conclusion For cataract patients with lens dislocation ≤120 °, implantation of intraocular lens in non-phacoemulsification capsular bag is feasible and safe.
