Posterior iris chafing by the loop or the optic portion of sulcusfixated posterior chamber lens implants may cause a spectrum of disorders that include iris-pigment epithelial "window defects," pigment dispersion with or without elevation of intraocular pressure, intermittent microhyphemas with transient visual obscurations, and the UGH syndrome. It appears that secondary pigmentary glaucoma is more likely with planar loop design than with angulated loops. Optic and loop materials may play a role in the development of the disorder. Implantation of both supporting loops of the implant within the capsular bag is suggested to prevent posterior iris chafing.
襻或沟固定后房型人工晶状体的光学部分对虹膜后表面的摩擦可能会引发一系列病症，包括虹膜色素上皮“窗孔缺损”、伴有或不伴有眼压升高的色素播散、间歇性小前房积血伴短暂视力模糊以及UGH综合征。似乎平面襻设计比有角度的襻更易引发继发性色素性青光眼。人工晶状体的光学部分和襻的材料可能在该病症的发生中起作用。建议将人工晶状体的两个支撑襻植入囊袋内以防止虹膜后表面受到摩擦。
