To evaluate the visual results and postoperative complications of capsular bag and ciliary sulcus fixation of posterior chamber intraocular lenses (IOLs) for traumatic cataracts in children.
Department of Ophthalmology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
Twenty children (20 eyes) with traumatic cataracts had extracapsular cataract extraction (ECCE) and posterior chamber IOL implantation. They were randomly divided into 2 groups. Capsular bag fixation was performed in 10 children (Group A) and ciliary sulcus fixation in the other 10 (Group B). Traumatic cataracts associated with large corneal lacerations (10.0 mm or more), hyphema, angle recession, or posterior segment involvement were excluded. The best corrected visual acuity (BCVA) as well as early and delayed postoperative complications were prospectively evaluated in both groups.
The BCVA was 6/12 or better in 9 eyes (90%) in Group A and 8 eyes (80%) in Group B at the end of the mean follow-up (24.6 months +/- 10.6 [SD]). Amblyopia (1 eye in Group A) and corneal scar and commotio retinae (1 eye each in Group B) accounted for a visual acuity of worse than 6/12. The residual refractive error did not exceed 3.50 diopters in either group. The incidences of fibrinous anterior uveitis and pupillary capture were significantly higher in Group B (P < .05, Fisher exact test).
Capsular bag fixation of posterior chamber IOLs provided visual results similar to those with ciliary sulcus fixation but was associated with fewer postoperative complications, particularly uveitis and pupillary capture. This represents another important reason to attempt in-the-bag fixation in cases of traumatic cataract.
评估儿童外伤性白内障后房型人工晶状体(IOL)囊袋内固定和睫状沟固定的视觉效果及术后并发症。
印度昌迪加尔医学教育与研究研究生院眼科。
20例(20眼)外伤性白内障患儿接受了白内障囊外摘除术(ECCE)及后房型IOL植入术。他们被随机分为2组。10例患儿(A组)行囊袋内固定,另外10例(B组)行睫状沟固定。排除伴有大角膜裂伤(10.0mm或以上)、前房积血、房角后退或后段受累的外伤性白内障。对两组患儿的最佳矫正视力(BCVA)以及术后早期和晚期并发症进行前瞻性评估。
平均随访结束时(24.6个月±10.6[标准差]),A组9眼(90%)、B组8眼(80%)的BCVA达到6/12或更好。弱视(A组1眼)以及角膜瘢痕和视网膜震荡(B组各1眼)导致视力低于6/12。两组的残余屈光不正均未超过3.50屈光度。B组的纤维蛋白性前葡萄膜炎和瞳孔捕获发生率显著更高(P<0.05,Fisher精确检验)。
后房型IOL囊袋内固定提供的视觉效果与睫状沟固定相似,但术后并发症较少,尤其是葡萄膜炎和瞳孔捕获。这是外伤性白内障病例尝试囊袋内固定的另一个重要原因。
