双撕囊人工晶状体植入术治疗先天性白内障临床观察

Double capsulorrhexis and intraocular lens implantation in congenital cataract

目的探讨先天性白内障术中行双撕囊人工晶状体植入的临床效果。方法观察组（A组）46例（48只眼）儿童先天性白内障行前后囊双撕囊联合人工晶状体植入术，对照组（B组）40例（42只眼）儿童先天性白内障行前囊撕囊、后囊抛光联合人工晶状体植入术，随访6～24个月比较两组的手术效果。结果术后矫正视力≥0．5者，A组33只眼（68．75％），B组10只眼（23．81％）；0．2～0．4者，A组13只眼（27．08％），B组22只眼培52．38％）；≤0．1者，A组2只眼（4．16％），B组10只眼（23．80％）。两组比较差异有显著性（x^2=5．46，P〈0．05）。后囊或中央视轴混浊≥3级者，A组10只眼（20．83％），B组18只眼（42．85％），两组比较差异有显著性（x^2=7．56，P〈0．05）。结论双撕囊人工晶状体植入术安全易掌握，组织损伤小，视力恢复好，可有效预防后发性白内障。

Objective To study the clinical effect of double capsulorrhexis and IOL implantation in congen - ital cataract surgery. Methods 48 eyes of 46 children patients in the treated group（ group A） underwent anterior and posterior capsulorrhexis combined with IOL implant-ation during the cataract surgeries while 42 eyes of 40 ch-ildren in the control group （group B） underwent only the anterior capsulorrhexis and the posterior capsule polishing . The clinical effects are compared during 6 to 24 monthsfollowing up. Results 33 eyes in group A（68.75 % ） and 10 eyes in group B （23.81%） get BCVA better than 0.5 post-operatively. 13 eyes in group A （27.08%） and 22 eyes in group B （52.38%） get BCVA between 0.2 and 0.4. 2 eyes in group A （4.16%） and 10 eyes in group B （23.80%） get BCVA lower than 0.1. There is statistical significance （ x^2 =5.46 , P 〈 0.05）. In 10 eyes in group A （20.83%） and 18 eyes in group B （42.85%）, opacities of the posterior caps-ules or the visual axis were observed. There is statistical significance（x^2 =7.56, P 〈 0. 05 ）. Condusion Double caps-ulorrhexis and IOL implantation is safe and easy to learn. It will lead less tissue damages and get a easy to learn. It will lead less tissue damages and get a better vision recovery. It can also prevent secondary cataract effectively.
