PURPOSE
To use very high frequency ultrasound scanning for in situ analysis of a new phakic posterior chamber intraocular lens (No-Touch; International Visions Inc, Cincinnati, Ohio).
METHODS
In this pilot study, very high frequency ultrasound (50 MHz) wide-angle (15 mm) full anterior segment scans were obtained in two patients who had undergone phakic posterior chamber intraocular lens implantation into legally blind eyes with normal anterior segment anatomy.
RESULTS
Very high frequency ultrasound B-scan images delineated the phakic posterior chamber intraocular lens within the posterior chamber. The relations to the sulci were clearly imaged. Anatomic relations of the phakic posterior chamber intraocular lens optic and haptics were visualized in both static (light/dark) and kinetic (distance/accommodative) states.
CONCLUSION
Very high frequency ultrasound wide-angle scanning provides a unique tool to noninvasively evaluate the eye preoperatively and the static and kinetic relations of this new refractive device within the posterior chamber.
目的
使用甚高频超声扫描对一种新型有晶状体后房型人工晶状体（无接触型；国际视觉公司，俄亥俄州辛辛那提）进行原位分析。
方法
在这项初步研究中，对两名前房解剖结构正常但已失明的眼睛植入有晶状体后房型人工晶状体的患者进行了甚高频超声（50兆赫）广角（15毫米）全眼前节扫描。
结果
甚高频超声B扫描图像勾勒出后房内的有晶状体后房型人工晶状体。与睫状沟的关系清晰成像。在静态（亮/暗）和动态（距离/调节）状态下均能观察到有晶状体后房型人工晶状体光学部和襻的解剖关系。
结论
甚高频超声广角扫描提供了一种独特的工具，可在术前对眼睛进行无创评估，并评估这种新型屈光装置在后房内的静态和动态关系。
