The realization that posterior chamber intraocular lenses have many advantages over anterior chamber ones has induced many practitioners to try methods of fixating the lenses in the ciliary sulcus when there is inadequate capsular support. Most of these methods require the use of sutures to anchor the lens to the sclera or the iris. We describe a modification of these techniques which allows the surgeon to place a stiff all-polymethylmethacrylate (PMMA) lens in the sulcus in a way that makes it unnecessary to anchor the lens, although a safety suture may be placed through the scleral lip. We believe this modification makes sulcus fixation simpler to perform and possibly safer for the patient. We have used this technique in six patients with good results.
后房型人工晶状体比前房型人工晶状体具有许多优势,这一认识促使许多从业者在囊膜支持不足时尝试将晶状体固定在睫状沟的方法。这些方法大多需要使用缝线将晶状体固定到巩膜或虹膜上。我们描述了这些技术的一种改良方法,该方法允许外科医生以一种无需固定晶状体的方式将硬质全聚甲基丙烯酸甲酯(PMMA)晶状体置于睫状沟中,尽管可以通过巩膜唇放置一条安全缝线。我们认为这种改良使睫状沟固定操作更简便,对患者可能更安全。我们已将该技术应用于6例患者,效果良好。
