A 44-year-old man with anterior megalophthalmos arrived at the clinic presenting a cataract in the right eye. The corneal diameter was 13 mm. Iridodonesis and phacodonesis were evident during slit lamp examination. Anterior chamber depth was 5.89 mm, and the diameter of the capsular bag was approximately 14.45 mm. Due to the large capsular bag, a standard posterior chamber intraocular lens was considered inadequate because of potential instability. Phacoemulsification and an implantation of an iris-claw lens (Artisan for aphakia(®), Ophtec) in the posterior chamber were performed with good results. In the fourth postoperative month, uncorrected distance visual acuity was 20/30, and 20/20 was achieved with +0.75 -1.25 × 10°. We consider retropupillary aphakic iris-claw intraocular lenses to be a worthwhile option in these cases of megalophthalmos and cataract, since instability is avoided and the procedure is less challenging than suturing the lens.
一名44岁患有先天性大眼球的男性患者前来诊所就诊，右眼患有白内障。角膜直径为13毫米。裂隙灯检查时可见虹膜震颤和晶状体震颤。前房深度为5.89毫米，囊袋直径约为14.45毫米。由于囊袋较大，标准的后房型人工晶状体被认为不合适，因为可能存在不稳定情况。于是进行了超声乳化白内障吸除术，并在后房植入了虹膜爪式人工晶状体（Ophtec公司的Artisan无晶状体眼人工晶状体®），效果良好。术后第四个月，未矫正的远视力为20/30，通过+0.75 -1.25×10°的镜片可矫正至20/20。我们认为，对于这些先天性大眼球合并白内障的病例，瞳孔后无晶状体眼虹膜爪式人工晶状体是一个值得选择的方案，因为它避免了人工晶状体的不稳定，而且该手术比缝合人工晶状体的手术难度小。
