Background. To evaluate the clinical efficacy of suture fixation of foldable intraocular lens (IOL) in ciliary sulcus guided by ultrasound biomicroscopy (UBM). Methods. Thirty-five eyes of 32 cases needing suture fixation of foldable IOL in ciliary sulcus in our hospital were collected and divided into two groups: group A and group B. In group A, UBM was performed on 19 eyes of 17 cases before surgery to locate the projection position of ciliary sulcus in iris surface. In group B, the traditional sulcus fixation of IOL was performed on 16 eyes of 15 cases. The inserting position of needles, the haptics position of IOL and the IOL tilt, and decentration were observed by UBM examination 3 months after the surgery. Meanwhile, the vision and contrast sensitivity were analysed. Results. The differences in inserting position of the needle, the IOL tilt and decentration, the ratio of IOL haptics in sulcus, and uncorrected visual acuity were statistically significant (P < 0.05). The differences in best corrected visual acuity (BCVA) and contrast sensitivity were not statistically significant (P > 0.05). Conclusions. Sulcus fixation of foldable IOL aided by UBM can increase the accuracy of IOL haptics implanted into ciliary sulcus and reduce the IOL tilt and decentration.
背景。评估超声生物显微镜（UBM）引导下可折叠人工晶状体（IOL）睫状沟缝线固定术的临床疗效。方法。收集我院32例需要行可折叠IOL睫状沟缝线固定术的患者的35只眼，分为A、B两组。A组17例19只眼，术前进行UBM检查以确定睫状沟在虹膜表面的投影位置。B组15例16只眼，采用传统的IOL睫状沟固定术。术后3个月通过UBM检查观察进针位置、IOL襻的位置、IOL的倾斜和偏心情况。同时分析视力和对比敏感度。结果。进针位置、IOL倾斜和偏心、IOL襻在睫状沟内的比例以及裸眼视力的差异有统计学意义（P < 0.05）。最佳矫正视力（BCVA）和对比敏感度的差异无统计学意义（P > 0.05）。结论。UBM辅助下可折叠IOL睫状沟固定术可提高IOL襻植入睫状沟的准确性，减少IOL的倾斜和偏心。
