The accuracy of preoperative biometry was tested in patients with transscleral suture fixation of the posterior chamber lens. Postoperative refraction and anterior chamber depth of 34 eyes that had been subjected to complicated cataract extraction with vitreous loss were compared with those in 17 fellow-eyes in which uncomplicated cataract extraction had been performed. The anterior chamber depth was significantly deeper after transscleral suture fixation of the posterior chamber lens (mean 0.59 mm, P < 0.05). The refraction differed by +0.68 D between transscleral suture fixation and the control group. We recommend that +0.5 D should be added to the calculated intraocular lens power if transscleral suture fixation becomes necessary during cataract extraction.
对行后房型人工晶状体经巩膜缝线固定术的患者进行术前生物测量准确性测试。将34只因复杂白内障摘除伴玻璃体丢失的患眼的术后屈光和前房深度，与17只进行了单纯白内障摘除的对侧眼的术后屈光和前房深度进行比较。后房型人工晶状体经巩膜缝线固定术后前房深度明显更深（平均0.59mm，P<0.05）。经巩膜缝线固定组与对照组的屈光相差+0.68D。我们建议，如果白内障摘除术中需要进行经巩膜缝线固定术，则应在计算的人工晶状体度数上加+0.5D。
