In eyes with either zonular dehiscence or weakness, application of CTR in high myopia cataract surgery associated with low diopter IOL implantation operation can prevent zonular dehiscence and IOL decentration and tilt, and may lead to prevent posterior capsular opacity and retinal detachment.

晶状体囊袋张力环在高度近视白内障联合低度数人工晶状体手术中的应用能防止晶状体悬韧带离断，使人工晶状体居中性更佳，并进而能有效防止后发性白内障和视网膜脱离的发生。

In posterior subcapsular cataract, there is disciform opaque beneath the posterior at early stage, composed of many dense punctates, with vacuoles and crystalloid granules among them, similar to the surface of slag brick called disciform cataract too.

初期晶体核呈黄色混浊，但很难与核硬化相鉴别。散瞳检查，在周边部环状红色反光中，中央有一暗影，眼底检查可由周边部看清。由于屈光力增加，可发生近视。可发生单眼复视或多视。

Methods The refractive state, corneal refractive power, anterior ocular segment length, vitreous length and ocular axial length were measured for 1 336 eyes, including 523 hyperopic eyes, 199 emmetropic eyes and 614 myopic eyes. The relationships of these elements were studied. Results CP had no effect on the refractive state.

检测1 336只眼的屈光状态、角膜屈光力（corneal refractive power， CP）、眼前节长度（anterior ocular segment length， ASL）、玻璃体腔径(vitreous cavity length， VL)及视轴长度(ocular axial length， AL)，其中远视523只眼，正视199只眼，近视614只眼。
