We compared the surgical results and complications between two groups of children operated for cataract with or without lens implantation.
One hundred seventy-five eyes in 126 children, aged 15 days to 16 years were operated for cataract with a surgical procedure of limbus phacoaspiration. Eighty-seven received a primary intercapsular one-piece PMMA Intra Ocular Lens (IOL). Conditions for lens implantation were restrictive: strictly intercapsular, no other ocular pathology, at any age in unilateral and usually after 3 years of age in bilateral cataracts. Follow up ranged from 6 months to 10 years.
Primary fibrinous anterior chamber reaction was seen in all patients in the IOL group. It always regressed under medical treatment. Glaucoma, retinal detachment and reoperations rates were similar in the two groups. There is a high correlation (p < 0.001) between initial anterior vitrectomy and keeping a clear visual axis, even in the eldest group, but no difference with or without IOL. Local tolerance of IOL was evaluated. No effect on visual results was evidenced. Evolution of refraction in pseudophakic eyes doesn't show evident myopic shift. Secondary myopias found in older groups might be associated to "genetic" myopia more than a consequence of implantation.
Intercapsular lens implantation in children does not statistically increase the rate of complication of cataract surgery. It can be chosen if a real functional benefit is expected. The choice of IOL's power depends on biometric results which are a function of age. Under correction is usually recommended but immediate emetropia must be the aim in unilateral cases to ease amblyopia's treatment.
我们比较了两组接受白内障手术的儿童的手术结果和并发症,一组植入晶状体,另一组未植入。
对126名年龄在15天至16岁之间的儿童的175只眼睛进行了角膜缘超声乳化白内障手术。87只眼睛接受了一期囊内一体式聚甲基丙烯酸甲酯人工晶状体(IOL)植入。晶状体植入的条件较为严格:严格囊内植入,无其他眼部病变,单侧白内障患者任何年龄均可,双侧白内障患者通常在3岁以后。随访时间为6个月至10年。
IOL组所有患者均出现原发性纤维素性前房反应。在药物治疗下,该反应总是会消退。两组的青光眼、视网膜脱离和再次手术率相似。即使在年龄最大的组中,初始玻璃体前切除术与保持清晰视轴之间也存在高度相关性(p < 0.001),但植入IOL与否并无差异。评估了IOL的局部耐受性。未发现对视觉结果有影响。人工晶状体眼的屈光变化未显示明显的近视偏移。在年龄较大的组中发现的继发性近视可能更多地与“遗传性”近视有关,而非植入的结果。
儿童囊内晶状体植入在统计学上不会增加白内障手术的并发症发生率。如果预期有实际功能益处,可以选择植入。IOL的屈光度选择取决于生物测量结果,而生物测量结果是年龄的函数。通常建议欠矫,但在单侧病例中,应旨在实现即时正视化以简化弱视治疗。
