A 5-year-old boy was referred to our clinic due to an abnormal visual acuity test at school. His corrected visual acuity was counting fingers in the left eye. A nasal side deficiency of the lens substituted by a membrane was found. Lens coloboma was diagnosed. After making a 3 mm limbal incision, the colobomatous lens was removed by anterior continuous curvilinear capsulorhexis and lens aspiration. Posterior capsulorhexis and anterior vitrectomy on the side of the lens was performed to prevent posterior capsular or anterior hyaloid opacity. As the defect in the lens was very large, intracapsular placement of an intraocular lens was not feasible. A three-piece acrylic soft intraocular lens was placed in the ciliary sulcus. Since amblyopia was diagnosed by poor corrected visual acuity as 20/800 1 month after the operation, occlusion therapy with correcting eyeglasses was started at 6 h a day on the contralateral eye. The patient's corrected visual acuity improved to 20/125 7 months after the operation.
一名5岁男孩因在学校视力测试异常被转诊至我们诊所。他的左眼矫正视力为眼前指数。发现晶状体鼻侧有缺损，被一层膜替代。诊断为晶状体缺损。在角膜缘做一个3毫米的切口后，通过前连续环形撕囊和晶状体抽吸术取出缺损的晶状体。进行晶状体侧的后囊膜撕开和前部玻璃体切除术，以防止后囊膜或前部玻璃体混浊。由于晶状体缺损非常大，囊内植入人工晶状体不可行。将一片式丙烯酸软性人工晶状体植入睫状沟。术后1个月因矫正视力差诊断为弱视，对侧眼开始每天6小时佩戴矫正眼镜进行遮盖治疗。术后7个月，患者的矫正视力提高到20/125。
