Recently, scleral fixation has been used in posterior chamber intraocular lens implantation in the absence of the posterior capsule. Fixation is achieved with a suture through the ciliary sulcus and sclera at a horizontal or vertical position. To achieve good functional results, the optical portion of the lens must lie on the optical axis. Unilateral lens implantation in the absence of the posterior capsule was performed with scleral fixation in 48 patients. Follow-up ranged from 14 months to 2.6 years. The position of the posterior chamber lens was defined in relation to the limbus and the pupillary margin. There was no evidence of lens decentration in miosis. Under conditions of extreme mydriasis, decentration of less than 1.0 mm was found in four patients; four others had approximately 1.5 mm of decentration. Magnetic resonance imaging was used to determine lens position in some cases. Scleral fixation is a viable alternative for implantation of posterior chamber lenses in the absence of the posterior capsule.
最近，在没有后囊的情况下，巩膜固定术已被用于后房型人工晶状体植入。通过缝线在水平或垂直位置穿过睫状沟和巩膜来实现固定。为了获得良好的功能效果，晶状体的光学部分必须位于光轴上。对48例无后囊的患者进行了巩膜固定的单侧晶状体植入。随访时间为14个月至2.6年。根据角膜缘和瞳孔边缘确定后房型晶状体的位置。在瞳孔缩小情况下没有晶状体偏心的证据。在极端散瞳情况下，4例患者发现偏心小于1.0毫米；另外4例患者有大约1.5毫米的偏心。在某些情况下，使用磁共振成像来确定晶状体位置。巩膜固定术是在没有后囊时植入后房型晶状体的一种可行替代方法。
