A single piece hydrogel IOGEL (poly-HEMA) intraocular lens was implanted in 76 eyes. Patients obtained a visual acuity of 20/40 or better in 86.9% of cases and a best case visual acuity of 20/40 or better in 98.5% of cases. Patients were followed an average of 12 months (four to 19 months). Two lenses were exchanged with poly(methyl methacrylate) lenses because of decentration-induced glare. Cystoid macular edema occurred in two cases, resulting in visual acuity worse than 20/40 in one case. Results of the study at one year mean follow-up indicate the safety and efficacy of the IOGEL lens as an intraocular implant.
将单片水凝胶IOGEL（聚甲基丙烯酸羟乙酯）人工晶状体植入76只眼中。86.9%的患者视力达到20/40或更好，98.5%的患者最佳视力达到20/40或更好。患者平均随访12个月（4至19个月）。因偏中心引起眩光，两枚人工晶状体更换为聚甲基丙烯酸甲酯人工晶状体。两例发生黄斑囊样水肿，其中一例视力低于20/40。一年平均随访的研究结果表明IOGEL人工晶状体作为眼内植入物的安全性和有效性。
