目的探讨瞳孔区机化膜原位切除联合后房型人工晶状体植入术治疗复杂型后发性白内障的方法和疗效。方法对33例37只眼复杂型后发性白内障患者行后发障原位切除联合后房型人工晶状体植入术,术后观察患者的视力、人工晶状体位置、后囊膜切除孔径面积变化情况及手术并发症。术后随访6~18个月。结果术后裸眼视力均优于术前矫正视力,其中≥0.3者28眼(75.7%),人工晶状体正位者33眼(89.2%),人工晶状体轻度倾斜4眼(10.8%)。术后6个月,后囊膜切除孔径增加3眼(8.1%),维持不变21眼(56.8%),减少13眼(35.1%)。无视网膜脱离。结论后发障原位切除联合后房型人工晶状体植入术是治疗复杂型后发性白内障的一种安全有效方法。
Objective To investigate the method and efficacy of mydriatic orthotopic removal combined with posterior chamber intraocular lens implantation for complicated posterior capsular cataract. Methods 33 cases of 37 cases of complicated cataract complicated posterior cataract were treated by posterior resection combined with posterior chamber intraocular lens implantation. The changes of visual acuity, intraocular lens (IOL) position and area of posterior capsular opening were observed after operation. Surgical complications. Follow-up 6 to 18 months after operation. Results The postoperative visual acuity of uncorrected visual acuity was better than that of preoperative visual acuity. Among them, 28 eyes (75.7%) were ≥0.3, 33 eyes (89.2%) were intraocular lens, and 4 eyes (10.8%) were intraocular lens. At 6 months after operation, posterior capsulotomy diameter increased by 3 eyes (8.1%), remained unchanged in 21 eyes (56.8%) and decreased in 13 eyes (35.1%). No retinal detachment. Conclusion Posterior chamber atherectomy combined with posterior chamber intraocular lens implantation is a safe and effective method for the treatment of complicated posterior chamber cataract.
