Phaco-Ersatz represents a new approach to cataract surgery and the correction of aphakia. The procedure involves the removal of the cataractous cortex and nucleus while preserving the lens capsule and its zonular attachments. The empty lens capsule is then refilled with biocompatible and optically suitable clear gel. A physiologic lens is recreated in situ. Experimental work with human cadaver eyes and rabbit and cat eyes in vivo demonstrates this surgical feasibility. A review of the literature reveals contradicting theories regarding the physical laws and lens properties governing accommodation. The accommodative potential of the ersatz lens has not been tested, but it may be speculated that this recreated lens may, in fact, possess some accommodative properties. Experimental investigations in this area represent the logical extension of intraocular lens implant development.
超声乳化替代术是一种治疗白内障手术及无晶状体矫正的新方法。该手术包括切除白内障皮质和核，同时保留晶状体囊及其小带附着。然后将空的晶状体囊用生物相容性好且光学性能合适的透明凝胶重新填充。在原位重建一个生理性晶状体。对人体尸体眼以及兔眼和猫眼进行的体内实验工作证明了这种手术的可行性。文献综述揭示了关于调节所涉及的物理定律和晶状体特性存在相互矛盾的理论。替代晶状体的调节潜力尚未经过测试，但可以推测这种重建的晶状体实际上可能具有一些调节特性。该领域的实验研究是人工晶状体植入发展的合理延伸。
