摘　　要：目的 :评价超声乳化的设备及操作技术在儿童白内障手术中的应用。方法 :对 6 6例 (82眼 ) 3～ 12岁的儿童白内障行白内障摘除及人工晶体植入术 ,术中应用了巩膜隧道切口及连续环形撕囊技术 ,并使用了超声乳化仪器的灌注抽吸系统清除软性晶体核及皮质 ,囊袋内植入人工晶体。结果 :术后矫正视力≥ 0 .5的 2 1眼 (2 5 .6 % ) ,视力在 0 .1～ 0 .4的 35眼 (4 2 .7% ) ,视力 <0 .1的14眼 (17% ) ,欠合作的 12眼 (14.6 % ) ,伴有斜视 12眼 ,眼颤的 5眼。术中前房发生不同程度纤维素性渗出有 2眼 (2 .4% )。术后前房有纤维素性渗出有 6眼 (7.3% )。其中 2眼有明显的膜性物形成 ,主要为外伤性白内障患者。术后随访发现瞳孔明显变形的有 4眼 (4 .9% ) ,其中轻度上移的 2眼 (2 .4% )。后囊膜混浊的 18眼 (2 2 .0 % ) ,其中 2眼需行 YAG激光后囊膜切开术 ,1眼伴人工晶体夹持需行晶体复位术。结论 :超声乳化设备及技术的应用 ,使儿童型白内障手术的手术合并症较传统的手术方法明显减少 ,为开展儿童白内障手术带来新的希望。to investigate the clinical application of phaco equipment and technique in children cataract surgery.Methods:The cataract surgery and IOL implantation were done on 66 cases(82 eyes)of children who were from 3 to 12 years old with scleral tunnel incision,continuous circular capsulorhexis,removing the lens with irrigation/aspiration system of phaco equipment and intracapsular IOL implantation.Results:The postoperative corrected visual acuity was more than 0.5 on 21 eyes (25.6%),from 0.1 to 0.4 on 35 eyes(42.7%),less than 0.1 on 14 eyes(17%),incorporation on 12 eyes(14.6%).Strabismus was found on 12 eyes with nystagmus on 5 eyes.Different degree of fibrous exudation in the anterior chamber were found on 2 eyes(2.4%)during the operation and on 6 eyes(7.3%)after the surgery with formation of membrane on 2 eyes,especially on the patients with traumatic cataract.In the follow-up period,there were 4 eyes (4.9%)with discoria and 2 eyes(2.4%)with slight ectopic pupils.The posterior capsular opacity were occurred in 18 eyes(22.0%)with YAG laser capsulectomy on 2 eyes and IOL reduction on 1 eye.Conclusion:The operative complications of children cataract surgery with the application of phaco equipment and technique were less than those with the traditional surgical methods.The new method brings a great hope to the children cataract surgery.
