【摘要】：目的观察超声乳化晶体摘除联合张力环并Ⅰ期人工晶体植入术治疗晶状体半脱位的效果。方法①晶体半脱位1个象限的患者30例(43眼),直接行超声乳化晶体核,吸净皮质,用旋转法植入(CTR),囊袋内植入人工晶体。②晶体半脱位于1~2个象限的患者111例(152眼),先用旋转法植入CTR,再超声乳化晶体核,吸净皮质,囊袋内植入人工晶体。③晶状体半脱位2个象限的患者21例(31眼),应用囊袋固定型张力环,采用聚丙烯缝线将张力环缝合固定于巩膜,拉紧张力环缝线至晶状体囊袋居正中,抽吸晶状体皮质,植入折叠式人工晶状体。结果 162例226眼患者,术后随访1~12个月,人工晶状体基本保持正位,裸眼视力≥0.5者199眼(88!)。结论超声乳化晶体摘除联合张力环并人工晶体植入,是晶体半脱位的首选治疗方法。脱位范围2个象限的患者可直接植入张力环,若脱位范围2个象限,则应缝线固定张力环。该手术方式可有效防止术后人工晶状体偏位的发生,大大提高患者的术后视力。
[Abstract]:Objective to observe the effect of phacoemulsification combined with tension ring and intraocular lens implantation in the treatment of subluxation of lens. Methods (1) 30 patients (43 eyes) with subluxation of lens in one quadrant were treated with phacoemulsification of lens nucleus and cortical aspiration. 111 patients (152 eyes) with intraocular lens subluxation in 1 ~ 2 quadrants were implanted in (CTR), capsule bag by rotation method. CTR, was implanted with phacoemulsification to remove the cortex. Twenty-one patients (31 eyes) with subluxation of intraocular lens (IOL. 3) were implanted in the capsule bag. The tension loop was sutured to the sclera by polypropylene suture, and the tension loop was tightened to the middle of the capsule bag. Pump the lens cortex and implant the foldable intraocular lens. Results 162 cases (226 eyes) were followed up for 1 ~ 12 months. Intraocular lens remained in positive position basically. The naked visual acuity was better than 0.5 in 199 eyes (88!). Conclusion phacoemulsification combined with tension ring and intraocular lens implantation is the first choice for the treatment of lens subluxation. Patients with dislocation range 2 quadrants can directly implant tension rings, and if dislocation ranges 2 quadrants, suture tension rings should be fixed. This method can effectively prevent the postoperative IOL deviation and greatly improve the postoperative visual acuity.
