目的观察囊袋夹持固定法植入人工晶状体治疗白内障手术中晶状体后囊破裂的效果。方法通过完全居中的、大小适宜的前囊连续环行撕囊,利用囊袋夹持固定法(人工晶状体光学部完全植入囊袋内而2个袢位于前囊前表面)使人工晶状体迭到稳定的囊袋固定,以处理白内障手术中发生的后囊破裂。分别对接受囊袋夹持法的13眼老年性白内障患者、4眼外伤性白内障患者、3眼先天性白内障患者进行随访观察。结果术后随访平均视力大于等于0.5的患者17眼(85%),夹持于囊袋的人工晶状体能够保持良好、稳定的居中位置,后囊破裂的大小稳定,所有术眼均未出现人工晶状体相关的葡萄膜反应。结论在后囊破裂较大,无法将人工晶状体植入囊袋内时,可以利用前囊撕囊孔进行囊袋内夹持固定法固定人工晶状体。良好的前囊连续环行撕囊不仅可以保证手术的安全性,而且是囊袋夹持法固定人工晶状体的必要条件。
Objective To observe the effect of intraocular lens implantation with capsular fixation in the treatment of posterior capsular rupture during cataract surgery. Methods Continuous central capsulorhexis was performed with a completely centered, appropriately sized anterior capsule. The intraocular lens was brought to a stable state by means of capsular retention and fixation (the intraocular lens optics was completely implanted in the capsular bag and the two ridges were located in the anterior surface of the anterior capsule) The capsular bag was fixed to handle posterior capsular rupture that occurred during cataract surgery. 13 cases of senile cataract patients, 4 eyes of traumatic cataract patients and 3 eyes of congenital cataract patients who underwent capsular clamping were followed up. Results 17 eyes (85%) with average visual acuity of 0.5 or more were followed up. The intraocular lens held in the capsular bag was able to maintain a good and stable position, the size of the posterior capsule rupture was stable, and no intraocular lens was seen in all eyes Related uveal responses. Conclusion When the rupture of the posterior capsule is large and the intraocular lens can not be implanted into the capsular bag, the capsulorhexis can be used to fix the intraocular lens in the capsular bag. A good anterior continuous capsulorhexis anterior capsulorhexis not only ensure the safety of surgery, but also the capsule holding the necessary conditions for intraocular lens fixation.
