Although the design of PMMA intraocular lenses has reached a stage of sophistication at which further modifications are unlikely to result in any major improvements in implant surgery, new materials with possibly improved mechanical and biologic properties should be evaluated carefully. The hydrogel lens (containing 38% poly-HEMA) is a soft, flexible, hydrophilic "single-piece" posterior chamber lens which could help to minimize intraoperative and postoperative IOL trauma. Fifty hydrogel intraocular lenses were implanted during a ten-month period using a standard extracapsular cataract extraction technique. Implantation was considered easy in most cases. As regards biocompatibility, stability of lens position, and visual acuity, the postoperative results are promising. In the follow-up period reported on, no central opacification of the posterior lens capsule was observed.
尽管聚甲基丙烯酸甲酯人工晶状体的设计已达到成熟阶段，在此阶段进一步改进不太可能在植入手术中带来任何重大改善，但仍应仔细评估具有可能改善的机械和生物学特性的新材料。水凝胶晶状体（含38%聚甲基丙烯酸羟乙酯）是一种柔软、可弯曲、亲水性的“一体式”后房型晶状体，有助于将术中及术后人工晶状体创伤降至最低。在十个月的时间里，采用标准的囊外白内障摘除技术植入了50枚水凝胶人工晶状体。在大多数情况下，植入被认为很容易。就生物相容性、晶状体位置稳定性和视力而言，术后结果很有前景。在所报告的随访期内，未观察到晶状体后囊中央浑浊。
