Intraocular lenses are a wise choice in a limited number of traumatic cataracts. It is necessary, however, to evaluate the patient very closely preoperatively to be assured that preoperative problems associated with increased postoperative complication are not present. In the proper patient, these authors feel that implant surgery is indicated. It offers a satisfactory alternative to the occasional patient that would have a functionless or amblyopic eye with a contact lens. Although the patient with a contact lens may see well with the contact in place, many are not able to wear the contact lens long enough during the day to consider it a functional success. These authors stress the use of a lightweight two-loop iridocapsular lens with one stage surgery and a short interval between the development of the cataract and the operation. Contact lenses or aphakic glasses are safe and will suffice with bilateral congenital cataracts. At the present time, further experimentation is necessary to determine if intraocular lens placement in the two-month-old infant with a unilateral congenital cataract will be safe and wil restore vision.
人工晶状体对于少数外伤性白内障来说是明智之选。然而，术前必须对患者进行非常仔细的评估，以确保不存在与术后并发症增加相关的术前问题。对于合适的患者，这些作者认为植入手术是可行的。对于那些因佩戴隐形眼镜而导致眼睛无功能或弱视的患者，它提供了一个令人满意的选择。虽然佩戴隐形眼镜的患者在佩戴时视力可能良好，但许多人无法在一天中长时间佩戴隐形眼镜，因此不能认为这是功能性的成功。这些作者强调使用轻巧的双袢虹膜囊袋内晶状体，采用一期手术，且白内障形成与手术之间的间隔时间要短。隐形眼镜或无晶状体眼镜是安全的，对于双侧先天性白内障来说就足够了。目前，有必要进一步试验以确定在两个月大的单侧先天性白内障婴儿中植入人工晶状体是否安全以及能否恢复视力。
