The pre- and postoperative results of ultrasonographic measurements on the axial ocular components in 10 phakic eyes with retinal detachment treated with encircling silicone rubber band are presented. A significant increase (P less than 0.001) in axial eye length from 0.62 to 1.24 mm (average: 0.98 mm) was found. The elongation of the eye was caused by a corresponding increase in the length of the vitreous cavity. No significant changes were found in the anterior segment of the eyes. These data demonstrate that the postoperative refractive change in a myopic direction, which an encircling procedure with moderate indentation often produces, is caused by an axial elongation of the eye.
本文呈现了10只使用硅胶环扎术治疗视网膜脱离的有晶状体眼，术前及术后超声测量眼轴各部分的结果。发现眼轴长度从0.62毫米显著增加至1.24毫米（平均增加0.98毫米）（P<0.001）。眼轴的延长是由玻璃体腔长度相应增加所致。眼前节未发现显著变化。这些数据表明，中等压陷的环扎术通常导致的近视方向术后屈光改变是由眼轴延长引起的。
