The NASA-McGannon cataract fragmentor, a newly designed mechanical phacofragmentor powered by compressed air, was tested on 100 eyes of old rabbits and on 50 dark brown nuclei of human cataracts that were implanted in the anterior chambers of rabbit eyes after the lenses had been removed. It was possible to eliminate the eddy current in the anterior chamber, reduce the requirement for infusion, and reduce the time of fragmentation both for rabbit lenses and for implanted hard nuclei of human cataracts. Iatrogenic damage to the iris and posterior capsule of the lens was noted in the early cases but not in the later ones, as the operators became more skillful in manipulating the instrument.
美国国家航空航天局-麦甘农白内障粉碎器是一种新设计的由压缩空气驱动的机械性晶状体粉碎器，已在100只老年兔眼以及50个人类白内障的深棕色晶状体核上进行了测试，这些晶状体核是在摘除兔眼晶状体后植入前房的。该粉碎器能够消除前房中的涡流，减少灌注需求，并缩短兔眼晶状体以及植入的人类白内障硬核的粉碎时间。在早期病例中发现了对虹膜和晶状体后囊的医源性损伤，但在后期病例中未发现，因为操作人员在操作该器械时变得更加熟练。
