Twenty-two dislocated lenses were removed using cryoextraction. They occurred in a consecutive series of 1,800 planned intracapsulars. Included in the complete series were 16 dislocated lenses in 3 groups: Marfan's syndrome, homocystinuria and congenital types of dislocations. None of these were removed since the patient's vision was adequate in each case. These patients are still under observation. In one case, we used the Hagler-Calhoun double pronged needle. We think this procedure is entirely too traumatic. In 21 cases, the dislocated lenses were removed intracapsularly. In one instance, the lens nucleus had been dislocated in an earlier operation, and there was advanced secondary glaucoma. The lens was removed with cryosurgery, resulting in a useful eye with no pain. Cryoextraction of dislocated lenses is the least traumatic surgical approach and is the method of choice.
采用冷冻摘除术取出了22例脱位晶状体。它们出现在连续的1800例计划内囊内摘除术中。完整系列包括3组中的16例脱位晶状体：马方综合征、同型胱氨酸尿症和先天性脱位类型。由于每例患者视力尚可，这些脱位晶状体均未摘除。这些患者仍在观察中。有1例，我们使用了哈格勒-卡尔霍恩双叉针。我们认为该操作创伤太大。21例脱位晶状体通过囊内摘除术取出。有1例，晶状体核在早期手术中已脱位，且存在晚期继发性青光眼。采用冷冻手术摘除晶状体，术后患眼有用且无疼痛。冷冻摘除脱位晶状体是创伤最小的手术方法，也是首选方法。
