The high prevalence of mature, hypermature, and traumatic cataracts in developing countries, combined with the limited availability of surgical resources and skill by anterior segment surgeons to manage the resultant aphakia, leaves the patient needlessly blind. Relying on posterior segment surgeons, expensive surgical setup, and appropriate lenses for aphakia management limits the number of patients receiving a secondary intraocular lens (IOL). Utilizing the well-acknowledged flanging technique and the readily available polymethyl methacrylate (PMMA) lenses with dialing holes in their optic, a hammock can be created through the dialing holes using a 7-0 polypropylene suture on a straight needle. This 4-flanged scleral fixation through the dialing hole of an IOL makes scleral fixation of PMMA lens possible by even anterior segment surgeons without requiring any specialized equipment or scleral fixated lens with eyelet. This technique was successfully performed in a series of 103 cases with no incidence of IOL decentration.
发展中国家成熟性、过熟性和外伤性白内障的高发率,加上前段外科医生处理由此导致的无晶状体眼的手术资源和技能有限,使得患者无辜失明。依靠后段外科医生、昂贵的手术设备和用于无晶状体眼管理的适当镜片,限制了接受二次人工晶状体(IOL)的患者数量。利用公认的翻边技术和带有拨号孔的现成聚甲基丙烯酸甲酯(PMMA)镜片,通过在直针上使用 7-0 聚丙烯缝线,可在拨号孔中创建吊床。通过 IOL 的拨号孔进行 4 个翻边巩膜固定,即使是前段外科医生也可以对 PMMA 镜片进行巩膜固定,而无需任何特殊设备或带环的巩膜固定镜片。该技术已成功应用于 103 例患者,无一例发生 IOL 偏心。
