The IOGEL 1003 hydrogel lens, designed for better capsular bag fit, was implanted in 100 consecutive eyes. We evaluated the visual and morphological results obtained with a mean follow-up of six months. Visual acuity was within Food and Drug Administration standards; however, morphological results were less satisfactory. Decentration of 1 mm or more occurred in 24% of the cases. Higher diopter lenses required a minimum incision size of 4 mm and tended to tear when folded. Once in the eye, they regularly came in contact with the iris. A gap between the posterior optic surface and capsule occurred in 61% of eyes. Within the short follow-up period, 9% of eyes required YAG discission because of Elschnig pearl formation. In conclusion, the newer IOGEL 1003 lens performed no better than earlier IOGEL lens models when placed in the bag, and the possible benefit of decreasing posterior lens subluxation after early YAG capsulotomy is offset by the disadvantages.
专为更好地适配囊袋而设计的IOGEL 1003水凝胶晶状体被植入100只连续的眼中。我们评估了平均随访六个月所获得的视觉和形态学结果。视力符合美国食品药品监督管理局的标准；然而，形态学结果却不尽人意。24%的病例出现了1毫米或更大程度的偏心。更高屈光度的晶状体需要至少4毫米的切口大小，并且折叠时容易撕裂。一旦植入眼内，它们经常与虹膜接触。61%的眼睛后光学表面与晶状体囊之间出现间隙。在短随访期内，9%的眼睛因Elschnig珠形成而需要进行YAG切开术。总之，新型的IOGEL 1003晶状体在植入囊袋时并不比早期的IOGEL晶状体型号表现更好，早期YAG晶状体囊切开术后减少晶状体后脱位的可能益处被其缺点所抵消。
