To compare the functional outcome of epilenticular intraocular lens (IOL) implantation vs the technique of anterior continuous curvilinear capsulorhexis (ACCC), posterior continuous curvilinear capsulorhexis (PCCC) with vitrectomy and in-the-bag IOL implantation in paediatric cataract surgery.
Forty eyes of 33 children with developmental or traumatic cataract, whose mean age was 2-12 years, were randomly divided into two groups A and B. Group A patients underwent epilenticular IOL implantation while in group B patients, ACCC, PCCC with anterior vitrectomy with in-the-bag IOL implantation was performed. Equal number of eyes (10 each) with developmental cataracts (subgroups A1 and B1) and traumatic cataracts (subgroups A2 and B2) were allotted to both the groups. Postoperative visual acuity, opacification of the visual axis, and possible complications were observed and analysed.
Four eyes in subgroup B2 had fibrous or ruptured capsules, and were managed by epilenticular IOL implantation technique. One eye in subgroup B2 developed central posterior capsular opacification and hence required a secondary capsulotomy. All cases in group A maintained a clear visual axis at the last follow-up. Minimal postoperative inflammation was noticed in all groups, which subsided with anti-inflammatory medication. At the last follow-up, all eyes in group A gained visual acuity >/=6/18. Whereas in group B, visual acuity >/=6/18 was obtained in 85.7% cases with the epilenticular IOL implantation technique and in 83.3% cases with ACCC and PCCC with anterior vitrectomy technique.
Epilenticular IOL implantation offers a safe and effective alternative for management of paediatric cataract. In selected cases of traumatic cataract, it is the preferred treatment modality.
比较小儿白内障手术中晶状体前房型人工晶状体(IOL)植入术与前连续环形撕囊(ACCC)、后连续环形撕囊(PCCC)联合玻璃体切除术及囊袋内IOL植入术的功能结局。
将33例平均年龄2至12岁的发育性或外伤性白内障患儿的40只眼随机分为A、B两组。A组患者接受晶状体前房型IOL植入术,而B组患者则进行ACCC、PCCC联合前部玻璃体切除术及囊袋内IOL植入术。两组均分配了相等数量的发育性白内障眼(各10只,A1和B1亚组)和外伤性白内障眼(各10只,A2和B2亚组)。观察并分析术后视力、视轴混浊情况及可能出现的并发症。
B2亚组中有4只眼出现纤维性或破裂的囊膜,采用晶状体前房型IOL植入技术进行处理。B2亚组中有1只眼发生中央后囊膜混浊,因此需要进行二次撕囊术。A组所有病例在最后一次随访时视轴保持清晰。所有组术后炎症均轻微,使用抗炎药物后消退。在最后一次随访时,A组所有眼的视力均≥6/18。而在B组中,采用晶状体前房型IOL植入技术的病例中85.7%的眼视力≥6/18,采用ACCC和PCCC联合前部玻璃体切除术技术的病例中83.3%的眼视力≥6/18。
晶状体前房型IOL植入术为小儿白内障的治疗提供了一种安全有效的替代方法。在某些外伤性白内障病例中,它是首选的治疗方式。
